  • The purpose of this research is to provide basic data for future home office design by surveying office workers' opinions about home-based working. The study is based on a survey done with 215 office workers in Seoul. The major findings are as follows. Home-based working is viewed as affirmative among office workers. Office workers thing that 3 days a week is desirable for working at home. The first reason why they want to work at home is 'having more free time for other interests,' the second one is 'being more creative or concentrating on work.'and the third one is 'reducing the stresses from the loaded tasks and relationships between colleagues'. While the first reason why they don't work at home is 'the notion that home is one thing and work is another.' the second one is 'lack of relationships between people.' and the third one is 'unable to concentrate on work because of many house chores.

  • In this paper, generation form of displacement current was compared and measured with air-water interfacing induce monolayers which 8A5H with azobenzene and arac.acid mixed. Light response of two monolayers which chain length are different was compared and measured though they are the same isomer. The experimental results are as following; In the displacement current form of mixed monolayers and 8A5H, mixed monolayers which chain length is longer than that of 8A5H caused the displacement current about 40[fA] mole. This is the reason chain length of hydrophobicity in mixed monolayers is longer than that of 8A5H In the case of light stimulus mixed monolayers reacted less than 8A5H about 9[fA]. This is the reason molecule dynamic behaviour in cia and trans was net activated due to its very long chain length.

  • In this study, I have researched into the causes of defects in apartment house, The results of this study are listed below. (1) Water leakages which result from land sinking and cracks, results of misuse of back filling method, are the main reason of defects in civil engineering work and architectural work. (2) Inexperience and unwillingness are the main reason of defects in plaster work. (3) In windows work and painting work, the main reasons are lacks of precision construction and efflorescence resulting from outdoor air, respectively. (4) Defects in waterproofing work and electric work result from fault construction by low unit Costs. (5) Equipment work requires uses of standardized construction materials and management, and landscape architecture work requires minimizing human mistakes, for instance, degin carelessness. For the reasons stated above, the causes of defects in apartment house are insufficient construction labors, inferior construction materials, urgent construction process time, and conscientiousless industrialists who only seek after a profit margin.

  • This study is concerned with the relation between steelbelt width and belt edge separation of a tire. Belt edge separation causes tire burst and threatens passenger's safety. For the reason, it is important to predict durability caused by belt edge separation in the early stage of the tire structure design. Usually, passenger car tires have two layers of steelbelts having opposite steel cord's angles, which makes a shear behaviour between each belt layer. Shear behaviour is one of reason to cause belt edge separation. In this study, to predict belt edge separation, we suggested the prediction method of belt edge separation and evaluated the effect of steelbelt width on the belt edge separation using FEM. We also studied on main parameters to affect shear behaviour at the belt edge area.

  • Foreign learners are not focusing on "적" grammar. Therefore, the lack of materials on "적" is the reason that foreign learners use "적" in real life. In particular, when teaching the Chinese-dependent noun "적", there are some problems in making the Chinese equivalent of "적". more accurately understood by Koreans. In addition, when using grammar through analyzing the grammatical conjunction centered on "적" and the corresponding expression of Chinese, the main reason for the error is that there is no common concept and form in the mother tongue, so there is no consciousness. Therefore, it is difficult for learners to learn similar expressions that are not in Chinese or Korean. Therefore, this study aims to improve specific educational programs for Korean learners and Korean Chinese learners in terms of the time system and the corresponding performance of Chinese grammar and Chinese characters based on the previous version of "적".

  • Subdural hematoma in infants can be caused by abuse, and is thought to be more likely if subdural hematoma is associated with retinal hemorrhage and cerebral edema. In Japan, few doctors disagree that cases of subdural hematoma with retinal hemorrhage and cerebral edema with multiple findings on the body are more likely to have been caused by abuse rather than by household accident. On the other hand, in cases where there are no other significant physical findings, only subdural hematoma and retinal hemorrhage, there is a difference of opinion as to whether the injury was caused by an accident or abuse. The reason for this is that neurosurgeons in Japan promoted the concept that infants can develop subdural hematomas and retinal hemorrages due to minor trauma at home before the concept of abusive head trauma became known. In addition, the age distribution of subdural hematomas in Japan differs from that in other countries, with peaks at around 8 months, and the reason for this remains unclear. Therefore, the etiology of infant subdural hematoma in Japan needs to be investigated in greater detail.

  • Uihakyimmun (醫學入門) was written around 1580 by Li Ting (李梴) during the Ming Dynasty of China. Later, during the mid-Joseon period, Uihakyimmun (醫學入門) was introduced to Joseon and is believed to have contributed to the development of Joseon medicine. The importance of this Uihakyimmun (醫學入門) was especially evident as it was designated as a textbook for medical examination in the late Joseon Dynasty. This paper examines the process of Uihakyimmun (醫學入門) being introduced into Joseon based on historical records. It also considered the reason why Medical Education was selected as the textbook for the medical examination instead of Donguibogam (東醫寶鑑). As a result, it was widely read by court doctors before being selected as a test textbook, and gradually became a formal textbook after being used in informal tests. In addition, it was revealed through historical records that the reason why Uihakyimmun (醫學入門) was chosen instead of Donguibogam (東醫寶鑑) was because Uihakyimmun (醫學入門) fit better with Confucian values.

  • The purpose of this study was to evaluate the perception and preference of Kimchi among the elementary school children. The survey was conducted via questionnaire to 439 elementary school children(224 males and 215 females) who lived in Seongnam. 77.2% of the surveyed children had an affirmative opinion of Kimchi intake. Children regarded Kimchi as traditional, nutritious, healthy, fermented and delicious food. It also revealed that the higher grade($4{\sim}6$ grade) students were more awareness in Korean traditional fermented healthy food as for Kimchi than the lower grade($1{\sim}3$ grade) students. They should eat Kimchi mainly because Kimchi is good for health(82.9%), nutritious food(62.9%), our traditional food(58.3%), and delicious food(41.5%). 73.9% of the children responded that the parents influenced on their consumption of Kimchi, but 16.5% of the children answered that their parents did not meddle. 67.3% of the children liked Kimchi, whereas 5.3% of them disliked it. The preference of Kimchi was significantly higher for lower grade students than for higher grade students. The main reason liking Kimchi was hot taste(60.8%) of Kimchi, and then texture of chewing(59.0%), taste of freshness (29.2%), cool taste(28.7%), and peculiar taste(26.9%) of Kimchi in order. The majority reasons for dislike the Kimchi were salty taste, hot taste, not eat oftenly, smell, appearance of Kimchi in order. The hot taste of Kimchi was the number one reason of their diskike of Kimchi, especially for lower grade students and female students, and it was the most important reason for those also like Kimchi. The children preferred the a little hot taste of Kimchi, properly fermented Kimchi, medium amount of seasoning in Kimchi, and any parts of Baechu in Kimchi.
