As a basic study for Man-Machine interfacing technics, this paper purposed the vertorization of EOG(electrooculogram) that is generated by eye movement. EOG is electric potential difference between the positive potential of cornea and the negative potential of retina. The magnitude and the polarity are depend on the direction of eye movement and degree of gaze angle. In order to vectorize EOG, EOG signal is measured about vertical and horizontal movement of eyes. This vectorization of EOG is expected to help Man-Machine Interfacing technics and development of other useful equipment.

For the efficient co-authoring of multimedia documents in a distributed systems environment, the cooperative-work management systems that can not only allow the sharing of distributed resources but also facilitate the authors' interaction, are needed. In this paper, we present a cooperative-work management system with hybrid architecture, called CW-MAN, in which the information on shared objects and co-authoring management is stored in a dedicated computer system but the shared objects distributed all over the local computer systems. The main management functions provided by the CW-MAN are those for shared objects, session, and telepointing. The shared-object use them exclusively. The session managements allows authors to dynamically create, update, and destroy sessions. Lastly, the telepointing management allows local pointing events to be synchronously presented to remote systems.

The purpose of this study was to quantify the relationship between the sense of touch and mechanical properties of man-made leather. The first was to develop the five conversion equations which convert mechanical properties of man-made leather into five factor scores, which express five factors of the sense of touch(surface property, stretchiness, thickness & weight, thermal property(warmth & coolness), and moisture property(sticky & clingy)). The second was to develop the conversion equation which converts five factor scores into score of the sense of touch. Five factor scores were predicted by the following mechanical properties; surface property factor by log2HB and (log2HB)2, stretchiness factor by logEM, thickness & weight factor by logT, log2HB, logW, thermal property factor by logT, logHB, logSMd, and moisture property factor by logMMD, RC, RC2, (logEM)2, RT2. Subsequently, these five factor scores were converted into score of the sense of touch. The predictive abilities of the developed equations were satisfied.

Nuclear power plant projects are being increased all over the world. The construction of nuclear power plants needs huge money and time, which makes conducting a detailed analysis of productivity through the whole process. Reinforced-concrete works productivity field data was collected for more than one year and analyzed from a nuclear-power-plant project in Korea. The productivities of formwork, rebar-work, and concrete pouring were $0.54m^2/man{\cdot}day$, $0.06ton/man{\cdot}day$, $1.98m^3/man{\cdot}day$, respectively. Moreover, it is revealed that 'Day of the Week' is a driver of the formwork activity and 'Overtime' is for all of the three. The results will be a great interest of industry personnel estimating time and cost of a new nuclear power plant.

This study examined the ideal type of a man that women prefer and the recognition of men for their own appearance management with the rise of the importance for appearance management today. The prerequisite which matters most in time of considering a man as a date of love predominantly was centered on education, and the prerequisite which goes first among the rest in time of judging a man as the mate of marriage was undoubtedly his financial status. It is regarded that as for a date of love the visual image or the specialty other than the conditions in reality mattered most, and concerning a mate in marriage the actual financial conditions had the priority. When a man is evaluated, the percentage of appearance took the highest rate of 60~80%, and in his appearance, the general harmony was considered as the most important factor. As for the recognition of men for their appearance management, women tend to have an affirmative realization for managing their own appearance in general, and the reason was they believe that the way men take care of their own appearance belongs to personal free will. The perception for a man with a decent appearance was very positive, and the ground for this was that once the appearance looks handsome, he seems gorgeous. The recognition for men's cosmetic surgery showed the affirmation over the average, and an opinion that the settlement of personal appearance complex will help them out emerged as the ground for this affirmation, and so it is regarded that the aesthetic surgery of today and the perception for men's appearance management have become universal phenomena unlike former days with the reflection of visualization of the external visual and lookism shown from various media.

The energy band method for NaI spectrum calculates only the exposure rate due to natural radiation because it calculates exposure rate using energy spectrum of $1300{\sim}3000keV$. However, the total energy method includes in its calculation the exposure rate due to man-made radiation because it uses the energy spectrum of $150{\sim}3400keV$. Therefore, the resulting difference of extracting the exposure rate calculated by the energy band method from the exposure rate calculated by the total energy method is apparently the exposure rate due to man-made radiation. In this study, we measured the NaI spectrum during the period of significant changes of the exposure rate in the area without a man-made radiation. As the results, we found the exposure rates calculated by those two methods are equal within the statistical variation of ${\pm}0.3{\mu}R\;h^{-1}$. Consequently, if the difference between the exposure rates calculated by the two methods exists, it may be due to the man-made radiation exposure rate.

This study examines the costume artifacts discovered in the burial site of Choi Kyung Sun(1561~1622), which was moved from Gangwon in Gangrung Province. About 30 artifacts, including costumes, were recovered from Choi Kyung Sun's grave. The collection of men's coats discovered in the grave consisted of a Dallyeong (Official's robe), Jing-nyeong(Man's coat), Jungchi-mak(Man's coat), Cheolrik(Man's coat), Chang-ui(Man's coat), Gwang-su-ju-ui(Man's coat), and Do-po(Man's coat). Han-sam(Undershirts), Jeo-go-ri(Jacket), and trousers were also recovered, along with several items made of textiles, such as the cloth used to shroud and wrap the body. The costume artifacts recovered from Choi Kyung Sun's grave have several characteristics that distinguish them from other early 17th-century costume artifacts. Firstly, the body had a hairband made from horsehair. Secondly, the men's trousers were of the type worn before the Japanese Invasion(1592~1597). Thirdly, the style of the coats' sleeves, when compared with artifacts from other regions, was from an earlier era. Through these costume artifacts, it can be inferred that people who lived in the Gangwon Province, which was far away from Seoul, continuously wore outfits from before the Japanese Invasion, and trends spread slowly.
