The purpose of this study is to investigate into the various ways that the computer technology is used for language testing. Three uses of computer technology are mentioned: 1) computer-adaptive language testing and computer-based language testing, 2) the scoring of performance-based language assessment, and 3) the development and use of psychometric tools for analyzing the scoring results. Although the various uses of computer technology could provide expanded possibilities for language testing development, the developers should be reminded that they are currently subject to indepth research which could support their validity. In this regard, the advantages and limitations of some uses of computer technology for language testing are discussed.

Objectives : The purpose of this paper is to study the form, contents and special features found in Qianhuang's life, books, his relationship with his disciples and Shanghansuyuanji's edition and its pass-ons. Methods : The best version among Shanghansuyuanji's copies was selected. Based on this, Qianhuang's life, books and his relationship with his disciples were studied, and Shanghansuyuanji's edition and its pass-ons, form and contents were analyzed. Results & Conclusions: Through study, first I see that Qianhuang was born in the early period of Qing Dynasty and died after the publication of Shanghansuyuanji, Suwen's annotation book probably had not been published yet, his mentor were Fangyouzhi and Yujiayan. Second, I see that he organized Shanghanlun sentences from his own perspective of cause of a disease and cure method. Third, I see that he viewed the diseases of six meridians with the perspective of yinyang and explained the concept of three yins and three yangs in relation to yinyang's ups and downs, and his Yuggyeongjasu theory made possible various interpretations of disease mechanism. Fourth, I see that he held critical views towards the Shanghanlun sentences through the Error Discrimination. Fifth, I see that he viewed disease mechaniam in interdependent relationships or from the point of view of the School of Warming and Tonifying through the Meaning of Herbal Formula. Sixth, I see that he sometimes quoted Neijing in proper ways that fit the disease mechanism in Shanghanlun. On the other hand, he quoted Neijing solely for the reason that identical words are used, but some of these were not proper. Additionally, he criticized the aforementioned annotators for improper quoting Neijing. Consequentially, for reasons mentioned above Qianhuang's Shanghansuyuanji has great importance as a Shanghanlun annotation book.

The objective of this paper is to present an analytical solution in deep water waves and verify the validity of the theory (Shin, 2015). Hence this is a follow-up to Shin (2015). Instead of a variational approach, another approach was considered for a more accurate assessment in this study. The products of two coefficients were not neglected in this study. The two wave profiles from the KFSBC and DFSBC were evaluated at N discrete points on the free-surface, and the combination coefficients were determined for when the two curves pass the discrete points. Thus, the solution satisfies the differential equation (DE), bottom boundary condition (BBC), and the kinematic free surface boundary condition (KFSBC) exactly. The error in the dynamic free surface boundary condition (DFSBC) is less than 0.003%. The wave theory was simplified based on the assumption tanh $D{\approx}1$ in this paper. Unlike the perturbation method, the results are possible for steep waves and can be calculated without iteration. The result is very simple compared to the 5th Stokes' theory. Stokes' breaking-wave criterion has been checked in this study.

The energy conservation theory is introduced for investigating processes of runoff and soil erosion on the hillslope system changed vegetation condition by wildfire The rainfall energy, input energy consisted of kinetic and potential energy, is influenced by vegetation coverage and height. Output energy at the outlet of hillslope is decided as the kinetic energy of runoff and erosion soil, and mechanical work according to moving water and soil is influenced dominantly by the work rather than the kinetic energy. Relationship between output and input energy is possible to calculate the energy loss in the runoff and erosion process. The absolute value of the energy loss is controlled by the input energy size of rainfall because energy losses of runoff increase as many rainfall pass through the hillslope system. The energy coefficient which is dimensionless is defined as the ratio of input energy of rainfall to output energy of runoff water and erosion soil such as runoff coefficient. The energy coefficient and runoff coefficient showed the highest correlation coefficient with the vegetation coverage. Maximum energy coefficient is about 0.5 in the hillslope system. The energy theory for output energy of runoff and soil erosion is presented by the energy coefficient theory associated with vegetation factor. Also runoff and erosion soil resulting output energy have the relation of power function and the rates of these increase with rainfall.

Wearing a clothes in human living is very rightful and reasonable things. And it's also the necessaries of living. So now, I want look around about origin of clothes from the prehistorical age, how they start and why they need to wear a clothes. As human culture is unknown origin, human clothes origin is also unknown origin, too. So many different people made unlike story about that, and it is very difficult to say correct birth of clothes. It must be reflection by a time, by a place, by a mankind, until this days, the history of human progress is $2,000,000{\sim}3,000,000$ years. And from after the "Old Adam" man understand what is shame and disgrace, so that made them cover of their private parts, also it is a motive of human clothes. Since after pass a long time, the earth has many changes as it were weather, and for take care of human body from cold, people start make clothes and it's a second object of wearing a clothes. And third object of wearing clothes is after opportunity of development human culture, people desire for an aesthetic sence and for full-fill that feeling they start make a beautiful clothes with accessories and it is motive and a purpose of a human start wear a clothes. So I can say, for origin birth of clothes is 1. Protect of human body. 1) be adapted for different weather and different circumstance. 2) take care self from outside injurg. 2. Decorate for aesthetic sence. 1) Theory of Amulets. 2) Theory of symbolism. 3) Theory of Sex attraction. 4) Aesthetic Theory. 5) Theory of chastity. 6) Multi-theory And material for clothes they made from natural wilds like leaves, fur, skin of wood. skin of fishes and feather etc. But after develop of human knowledge people invent fiber, and use a knitted goods and woven stuff also first of all. They start use those kind that they just cover of their private parts as a belt and astring with leaves and a beast skins. But until this days it's taken big development with human knowledge and most important influence of develop was weather. So modern clothes for present days, must care with. physicology, preservation of health, living activity, dressing, morals, and etiquette etc.

본 연구는 인간을 다른 생명체와 동일한 차원에서 바라보는 인간주의 이후 포스트휴머니즘의 흐름과 더불어, 그 안에 속하지만 정반대로 과학기술을 통한 증강인간을 꿈꾸며 절대화를 꾀하는 트랜스휴머니즘의 문제를 다루고자 한다. 그 이후 본 연구는 기존 정의론이 이 두 가지 양극단의 상황에 대해 어떻게 평가할 수 있는지 살펴보고자 한다. 특별히 정의론과 관련하여 우리가 선택한 길잡이는 마이클 샌델이며, 이러한 논의 안으로 미래의 포스트/트랜스휴머니즘의 문제를 통과시켜봄으로써 과연 전통 정의론의 입장에서 미래 인간론의 흐름을 어떻게 평가할 수 있는지 제안하게 된다. 포스트/트랜스휴머니즘과 그로 인해 나타날 다양한 사건들은 우리가 피할 수 없는 운명으로 다가오고 있다. 그러나 이러한 필연적인 상황과 더불어 이것은 기존의 정의론을 통과하여 타당한 것으로 통용되기 위해서는 아직 많은 논의들이 필요한 실정이다.

This study investigated the cognitive process of 5-year-old children, with a particular focus on gender, monthly age, and their tendencies towards hyperactivity through the performance of the Cognitive Assessment System (CAS; Das & Naglieri, 1997). The children with tendencies towards hyperactivity were identified based on Conners Teachers' Rating Scale (CTRS). The subjects were 75 five-year-old children in Seoul and surrounding metropolitan areas. Data were analyzed by means of descriptive statistics, an independent sample t-test, Pearson's correlation coefficient, one-way ANOVA, and by K-mean cluster analysis. Our results were as follows : (1) The CAS and CTRS' sub-factors were correlated negatively, except the positive correlation between planning factor and hyperactivity factor. (2) Girls exhibited significantly higher CAS scores in planning & sequential processing than boys. (3) The upper monthly age group (68-71 months) showed significantly higher score in terms of planning than the lower monthly age group (60-63 months). (4) The CAS scores of the children with tendencies towards hyperactivity was lower than that of normal children. (5) The CAS profile of 5-year-old children was divided into 4 groups with distinctive characteristics by means of K-mean cluster analysis.

Passive sonar in submarine can detect the target in long range and can attack using it. There are many noises which can be received at passive sonar of submarine. When noise received in the sonar it make diverse interference pattern depend on the ocean ambient and movement scenario. Interference pattern can be explained by theory of waveguide invariant. In this paper, analyze the interference pattern according to the relative motions of surface ship and submarine. And analyze the occurrence reason of 2 kinds of interference patterns those are usually display on the submarine console. The results show that if relative speed of submarine and target increase then gradient of interference pattern will increase. And closest point approach of submarine and target decrease then gradient of interference pattern will increase. Bathtube pattern usually appear when target pass though close to submarine and Pinetree pattern appear target pass though above of submarine.
