Reactive-etching system used etching a superconducting thin film. We obtained etching condition of superconductor (NbN) thin film. Etching speed is depends on etching time. Become known by no means proportion atching time. Next, insulator (MgO) layer etching process used low pressure Ar gas. This is mechanical energy etching. Etching speed is so late and give a photo resist damaged in a surface region on the collision with ionization Ar gas molecular. Bat insulator layer is about 10 [nm] value size that the little damage. Also a study of reactive-etching technology makes it clear that etching mechanism. Reactive-etching is secondary function relation was found between etching quantity and etching time at RF power is constant. Mechanical energy etching quantity is in direct proportion to etching time at RF power is constant.

This paper shows a style file of LATEX2e for Kisarazu National College of Technology bulletin. The TEX is a powerful document processing system. Donald E. Knuth first developed the TEX system when he was a professor at Stanford University. Than Dr. Leslie Lamport stengthened the TEX system by providing useful macros and than constructed the LATEX system. The new LATEX system which is called LATEX2e system has developed since 1993. The authers must write the bulletin in conformity with the writing rules. I think my style file and template file should help edit the bulletin.

In recent years, it is recognized that the plant of the waterside is effective for a function of back protection. And many researchers push forward investigation of back of a river protection by vegetation. However, there is much concrete shore protection and, in a small river, stays because management is easy. In addition, a Small river is in a condition that it was become a waterway. When I plant a stalk plant in a river made a waterway, scouring and a deposition action will start it. As a result, the shallows and a deep water are gradually formed in stream bed and small water-route is made. By doing this method at a suitable interval, it is enabled to be rich in a scene and to also provide an aquatic living thing with rich nature. This research gave vegetation to the riverbank, investigated about change of a flow, and we examined as one of the natura-friendly river improvement of construction.

This paper presents our attempt to educate not only analytical procedures but also design and presentation abilities to the students through a subject named "Environmental Engineering Laboratory". A report on amenity design of neighboring rivers based on the results of water quality investigation was included in the subject. Furthermore, the students were given an opportunity to present the results and their design at the last term of the subject. Those attempts resulted in a superior effect of environmental education on the students.

In higher education system, when students learn physics, to apply merely a formula for a gived problem and to solve a problem are not enough. I advise to students that to learn physics they find a problem by themselves and study it and to conclude their thought about it. We report the study method and situation of the physics that students used and describe our scholastic evaluation about them.

This work reports the performance of ultraviolet light emitting diodes (UV-LEDs) that have been actively developed in recent years. We examined whether the UV-LEDs become a new excitation source instead of the conventional UV-laser in fluorescence measurement of plant leaves. Some UV-LEDs provided sufficient irradiance and two dimensional distributions for the excitation. However, weak visible emission (400nm-600nm) existed besides main peak emission in ultraviolet region. Then, the fluorescence measurements were carried out by sbsorbing the visible emission from UV-LEDs with a UV transmitting filter (UV-D35).In addition, output level and peak spectrum of each UV-LED changed according to operative temperature. It has been understood that the temperature control of UV-LEDs is necessary. From the overall evaluation, it is concluded that the UV-LEDs can be used for an excitation source in the fluorescence measurement of plant leaves.

In the first students at KNCT (Kisarazu National College of Technology, in short) are requested to write essays in the lesson of English B, and their written passeges are analyzed from the points of writing materials, its volume, and its characteristics. In the second study we investigated the benefit of 2 hints in the reading comprehension. We administrated the experiment of the reading comprehension. The participants of the experiment is 28 nursing school students, 167 1st grade students of Kisarazu National College of Technology (KNCT) and 88 5th grade students of KNCT. These participants were divided into 2 groups. Group A and Group B. The participants of Group A were presented 5 pictures relevant to the content of the reading test text. The participants of Group B were presented Japanese translations of 6 English words used in the reading test text. The result wes following. According to the average score of the test, Group A is higher than Group B among the nursing school students. But the 1st grade students and 5th grade students of KNCT, the average score of Group B is higher than that of Group A. However there was no significant difference of t-test among 2 groups of the nursing school students and 1st grade and 5th grade students of KNCT. We concluded that there was no significant difference among 2 groups in the reading comprehension.

This study is aimed at investigating the development of syntax by immersion students at Kato Gakuen immersion school. The spoken data was examined in terms of sentence structures based on five sentence patterns; SV, SVC, SVO, SVOO, SVC. And it was compared with L1 and 12 acquisition findings. As a result, the first graders development in second language was depicted. Also the order of acquisition was not the same as either L1 or L2's. Especially, regarding dative structures the finding showed the similarity with that of lennerbility theory or markedness theory. This may require further investigation.

This article is based on the lecture I gave at the Ideaz-Institute (www.ideaz-institute.com) in Vienna on October 4, 2005. The subject of this meeting in Vienna was "Towards a Poly-Centric World", and I was requested to speak on "Walter Benjamin and Japan" from a cross-cultural point of view. In this lecture, I explained the reception and changes towards Walter Benjamin and his ideas in Japan since the 1970s. I also explained "Original Suprematism" and the principle, as well as the translations of his works, which have been considered to be humanities research in Japan. What must be stressed is the fact that Japanese philosophical reseachers think of philosophy as a universal science, so for them the view of cross-cultural content is not so important when they conduct their research. With this in consideration, one might soon recognize that one reason why W.Benjamin is so popular in Japan is because he himself had a strong tendency towards universality.

The purpose of this study was to measure blood pressure and heart rate (HR) during isometric-incremental handgrip exercise (IHG), and to clarify the difference between the effects of intermittent (Imt) and continuous (Cont) loading in IHG. To accomplish this, eighteen male subjects aged 20 years old attended this study as volunteers, and preformed two kinds of IHG on the same day (or on two different days respectively.). The IHG consisted of five incremental stages, whose intensities were set at 20, 30, 40, 50 and 60 percent (%) of maximal voluntary contraction (MVC) with IHG. The IHG was done at 20%MVC of load at first, the load was increased in 10% increments by 60%MVC. During Cont loading, contraction was maintained for ten-second intervals, continuously increased work load and kept IHG without a rest between exercise stages. During Imt loading, contraction was maintained for ten-second, subjects took sufficient time to recover until the next stage of exercise, and began the next exercise stage. Subjects carried out the IHG in a sitting posture. The target load was checked and adjusted through the display of a personal computer by a subject himself. During the IHG, arterial blood pressure and HR were continuously measured. During both Imt and Cont IHG, blood pressure and HR gradually increased according to increasing intensity of load. However, over 30%MVC, blood pressure and HR increased more significantly during Cont IHG than Imt trial. Pressor response of Cont IHG strongly correlated enhancement of blood pressure and HR with intensities, even though those makers of Imt IHG did not correlate significantly. According to those results, incremental continuous handgrip exercise induces a more obvious change in blood pressure even at 30%MVC for ten seconds than that of intermittent handgrip exercise. Therefore, continuous handgrip exercise would seem to be more effective in evaluating hypertension in the future.

Collaborative learning is one of the effective learning methods because the learner is led to deep understanding and to nature broad views and the creative skill. These effects are due to the interaction of the member of the group like the discussion etc. Therefore, it is important to offer a collaborative environment where such interactions occur easily. We are developing a collaborative learning support system. The system provides the knowledge data base and the function of the web forum. The knowledge data base used CmapTools to show knowledge visually. To put a mathematical symbol and figure easily on CmapTools and web forum, we devised the system by use of mimeTeX.
