최근 산업 발전과 더불어 대공간 건축물의 수요가 급증하고 있다. 이 분야 선진 기술은 지간 300m 이상의 대공간 건축물 실현도 가능하게 하고 있다. 대공간 구조에는 쉘구조, 스페이스 프레임 구조, 막구조, 케이블구조 등이 있다. 대공간 건축물은 기둥 없이 넓은 공간을 확보해야 하는 구조적 특성 때문에 설계초기 단계에서부터 시공문제를 병행하여 검토할 필요가 있다. 대공간 건축물 시공에 있어서 erection 공법은 공사비용, 공사기간 그리고 안전성 등에 큰 영향을 주는 것으로 알려져 있다. 대공간 건축물 erection 공법은 현장 여건 및 제반 조건에 따라서 그 수를 헤아릴 수 없을 정도로 많고 다양하지만, 대표적인 공법으로는 Element 방식, Block 방식, Sliding 방식, Lift-up 방식 그리고 복합방식 등이 있다. 본 연구에서는 기존 대공간 건축물을 대상으로 시공당시 적용한 erection공법을 조사하여 이것을 규모별, span별, 층고별, 구조형식별로 분석 및 검토하여 향후 대공간 건축물의 효율적 erection 공법 개발을 위한 기초 자료를 제공하는데 그 목적이 있다.

Studies and reports on buddhist temples in Goryeo dynasty are rarely in the present situation. At this point of time new excavational reports and historic records offer many materials to understand a architecture in Goryeo period. Especially, temple site have various transitions, it is of great value to study. This article attempted a restorative study of a location, function, spacial arrangement, structure, building age is based on a measure and transition of temple layout that is based on the excavational result and related historic documents about Godal temple site in Yeoju. Godal temple site was a representative Zen buddhist temple in Goryeo Dynasty. It was difficult of access by watercourse because it was located in an inland in the upper Han River. Archaeological research and historical records has reveals that the temple was constructed with a minium of four levels[six terms]. We could recognized the central site of temple and buildings were constantly established, enovated or collapsed. It has went through many transition according as it encountered new sects and doctrines. Also it should perform various functions and overcome given conditions. Ultimately it let see greater diversity in the spacial composition, and layout. That is to say it were planed several separate areas, each was consisted of main buildings, once again was integrated into one temple.

It can be concluded that the method and process described in this paper could be helpful for diagnosing the musculoskeletal disorders and making improvement plans to the autopart company and the same business field with similar working conditions and process.

There is no universally agreed classification of human error, nor is there one in prospect. Thus, a taxonomy is usually made for a specific purpose. To seek the types of human errors in the environment of man-machine interface under the railway industry, we develop a cognitive information processing model incorporating the human's mental states. Using the model, this study investigates the types of human errors about the railway workers. Thus, a survey is conducted for railway safety personnel-locomotive engineers, station employees, and train commanders- in Korean railway company. Through the survey that is designed to investigate four types of human errors from the Questionnaires composed of thirty Questions, we analyze the types of human errors related to railway safety according to affiliated offices, operation shifts, age, and working years. Finally, from the insights of the results some guidelines for the railway safety management are presented.

Ordinary concrete uses aggregate sufficiently soaked with water, and is weighed, mixed with other materials and placed in accord with performances required in the construction field. Recently special concrete with high fluidity and durability is required but it is difficult to use top-quality concrete due to lack of high-quality aggregate, delayed transportation because of traffic jam, etc. In addition, sometimes the use of a remicon is inevitable just for small-sized concrete constructions or it is difficult for a remicon to reach remote construction places such as mountainous areas. To solve these problems, this study attempted to pack concrete materials. In other words, it is to instantize concrete. This study dried aggregate, a material of concrete, and compared the change of absorption phase of the aggregate in water and in paste in order to examine the effect of the dryness of aggregate on its absorption rate and, based on the absorption rate, decided water addition ratio necessary for the reduction of unit quantity caused by the use of dry aggregate in designing concrete mixture, and analyzed the properties of unhardened concrete according to water addition ratio in manufacturing concrete using aggregate in the state of absolute dryness and in the state of surface dryness.

This study was to investigate distribution characteristics for air pollutants and to assess probability of health effect for children in kindergartens from August, 2006 to January, 2007. The mean concentrations for standards of maintenance in kindergartens were 91.5 ㎍/㎥ for PM10, 1,185 ppm for CO2, 69.3㎍/㎥ for formaldehyde, 174 CFU/㎥ for TBC and 0.41 ppm for CO, respectively. For NO2, Rn, TVOC, and O3, the mean concentrations in kindergartens were 29.40 ppb, 1.51 pCi/ℓ, 257.3 ㎍/㎥, and 3.74 ppb, respectively. The I/O ratio of every air pollutants exceeded "1" except for O3. In results of calculated safety factor to assess probability of health effect for children by air pollutants in kindergartens, safety factor for CO2 was 1.2 for fixed point. It means that children have probability of health effect caused by CO2. In cases of Monte-Carlo analysis, safety factor for PM10 was 1.0 and safety factor for CO2 was 1.2.

This research entailed collecting domestic and overseas research papers on technologies for fermentation of Kimchi, which is widely considered the national dish of Korea, creating a technology classification structure and conducting quantitative analysis on each technology component and schematization. Five research papers were published in domestic journals in 1990. Afterwards, the number increased by six to nine papers a year. There was no clear increase after the year 2000, but an average of around 20 papers have been Published every year, indicating that Kimchi research is now becoming widespread. An analysis on researchers entailed determining the percentage of research papers published by the top ten authors. The percentage was 76% in the early-1990s; 63% in the late-1990s; and 52% in the 2000s, indicating that Kimchi has been more and more widely researched and Kimchi research has become professionalized. Universities were found to be leading the research as 52% of researchers belonged to universities. Another 9% were at research institutions. Analysis of technologies showed that domestic research mainly focused on the Kimchi fermentation process and an additive for the development of new Kimchi ingredients and types, preservation and quality improvements. Most of the research papers published overseas dealt with the functions of bacteria strains isolated from Kimchi; and improvements in the Kimchi fermentation and ripening processes. And most of the research papers have been published in a field of microorganism and biotechnology.

There may be several factors influencing the safety performance of railway safety personnel. These include human psychological and physiological states, physical conditions about working environment, and workers' stress and fatigue etc. Some researches indicate that human personality is close connection with human error. This study focuses on the workers' personality which is one of psychological traits of railway safety personnel. Thus, we survey and analyze it for railway safety personnel-locomotive engineers, station employees, and train commanders-in Korean railway company. Through the survey that is designed to investigate eight safety personality factors from the questionnaires composed of seventy eight questions, we study the workers' personality factors related to railway safety according to affiliated offices, operations, age, and working years. Finally, after categorizing survey results into sixty six patterns, we explain an example to show a corresponding worker to the pattern result.

As many other countries, We have ‘presentence investigation system’ in Korean criminal justice system. But, in comparison with other country’s system like America or England, our system is imperfect. That is to say, our presentence investigation system is legally applied only to juvenile criminals. In addition, though Korean probation and parole office have the power of presentence investigation, this power is not effectively used. So, legally, adult criminals have been sentenced in a court without presentence investigation process. And consequently, their mental disorder, home background, social environment, the cause of crime and so on are not precisely considered in a court. So, such sentencing have some problems that is unscientific, regimental, and none effective to criminal’s treatment and rehabilitation. Fortunately, Presidential Committee on Judicial Reform has made a law about presentence investigation, but this law also have many problems. That is to say, this law rules the subject of presentence investigation dualistically - court official and probation officer. Such system is not discovered in any other country, and this may cause chaos of presentence investigation process and may result in the squandering of national budget. So, this article indicate the importance of complete presentence investigation system and that we should made a law of presentence investigation system more systematically and unitarily.

The purpose of this study is to establish English as elective subjects for 11~12 grades in Korean high schools. This study was conducted in the form of survey including a total of 1,923 participants, consists of 728 high school English teachers, 984 high school students, and 939 parents. The questionnaire consisted of nine questions, and which were designed to elicitate the participants perception and needs on English as the elective subjects in high schools. The results of the study indicate that 1) we need the subjects that include 4 skills(listening, speaking, reading, and writing), 2) binding listening and speaking skills together will meet the need of students and parents who want to choose conversation-only subjects, 3) on the other hand, binding reading and writing skills together will meet the needs of the students who want to prepare for establishing the academic basis in the future. 4) Various proficiency in English between students requires various level of the elective subjects in high school English. On the basis of these results, this study suggests we need 1) the subjects which deals with 4 skills on the basis of traditional concept, and 2) ‘listening and speaking’ subjects and ‘reading and writing’ subjects. And the subjects should have various levels between the highest level to the lowest level.
