The main idea of this report, which deals with the process analysis in outfitting fields, is to improve working methods and further to secure higher productivity by removing unreasonable work factors in the workshop with the economical point of view. For this purpose, a series of techniques has been applied to some parts of chronically less productive outfitting works, expecting less man hour consumption and better working conditions to go with it. That is to make full use of process chart flow diagram(man & machine chart gang process chart). The text gives brief introductions of the charts respectively and the appendix shows actual practice directly applicable for the guidance of utilizing these charts. As the result of this, some of unreasonable work factors are removed from the total cycle and finally standard working method & time can be come out by reasonable working time and gradually improved working method.

The intestinal immune system can discriminate between harmful and unharmful antigens and do not provoke productive immunity to unharmful antigen. Thus oral administration of antigen is one of classical methods for inducing antigen-specific immune tolerance in the periphery. Furthermore, oral tolerance has been investigated for the treatment of autoimmune disorders in human clinical trials. However, the detail mechanism of oral tolerance and contributing factors are not defined clearly at this time. Recent studies demonstrate unique types of immune cell that suppressing immune response, such as regulatory T cell and tolerogenic dendritic cell. This article reviews the factors involved in oral tolerance and discusses our current understanding base on the recent literatures and our works.

As buildings becoming higher and more enormous the portion of steel works has been increased, which makes the schedule planning and management more significant. However, in actual construction sites, management is more based on a manager's construction experience than productivity data accumulated in previous projects. Moreover, most of the existing studies also featured a theoretical approach rather than an analysis of data straightforwardly collected in sites. In this study, a steel-erection site was visited to collect productivity data. The study found that there were significant disparities between aboveground work productivity and underground work. However, the productivities of 'first node on ground' and 'second node on ground' were estimated similar. The productivity data collected and factors affecting the productivity will help managers to plan and control their similar steel-erection works. This study will also be beneficial for those performing related studies.

Enterprise Resource Planning(ERP) systems offer pervasive business functionality the applications encompass virtually all aspects of the business. Understanding and managing this pervasiveness will result in a successful and productive business application platform. Because of this pervasiveness, implementations have ranged from great successes to complete failures. This article has two distinctive parts. The first proposes and discusses a systematic process based on consulting experiences of LG CNS (leading information system company in Korea) for ERP selection. Also, the second provides the key factors that are critical to the successful implementation of ERP. The second part reports the results of a study carried out to assess a number of different ERP implementations in different organizations. A case study method of investigation was used, and the experiences of five Korean manufacturing companies were documented. The critical factors in the adoption of ERP are identified as: learning from the experiences of others, appointment of a process innovator, establishment of committees and project teams, training and technical support for the users, and appropriate changes to the organizational structure and managerial responsibilities.

본 연구는 강처분성의 가변수익규모 및 비방사적 자료포락분석기법을 이용해 조직유형이 다른 도시철도 운영기관인 서울시지하철공사(지방공기업)와 철도청의 수도권 전철부문(정부부처형 공기업) 및 부산교통공단(국가공단)의 연도별 생산적, 기술적 및 배분적 효율성 값을 추정한 다음, 이들 값에서 토빗회귀식의 추정결과를 이용해 조직유형과 궤도가동률과 같은 외부 요인들의 영향을 제함으로써 내부 요인인 생산활동만의 영향이 반영된 순생산적, 순기술적 및 순배분적 효율성 값을 구하였다. 또한 토빗회귀식의 추정결과로부터 세 도시철도 운영기관들의 조직효율성과 연도별 총효율성 값을 구하였다. 이 때 토시철도 운영기관은 노동, 전력, 전동차 및 유지보수와 궤도(또는 자본) 요소를 투입하여 전동차-km를 생산하는 기업형태로 상정되었으며, 분석에는 세 운영기관의 연도별 자료로 구축된 불균형통합자료가 사용되었다. 자료포락분석의 결과 생산적 효율성과 배분적 효율성은 평균적으로 서울시지하철공사가 가장 높은 반면, 기술적 효율성은 철도청의 수도권 전철부문이 가장 높은 것으로 나타났다. 그러나 생산활동만을 대상으로 추정된 순생산적 효율성과 순배분적 효율성은 오히려 부산교통공단이 가장 높은 반면, 순기술적 효율성은 철도청의 수도권 전철부문이 가장 높은 것으로 나타났다. 또한 이러한 순효율성들의 경우 외부 요인들의 영향이 배제됨에 따라 세 운영기관들의 차이는 상당히 감소하는 것으로 나타났다. 한편 조직효율성의 경우 비용을 극소화하는 조직유형은 지방공기업인 서울시지하철공사인 것으로 나타났으며, 이러한 조직효율성과 순생산적 효율성을 합한 총 효율성도 평균적으로 서울시지하철공사가 가장 높은 것으로 나타났다. 이러한 결과들은 도시철도 운영기관들의 경영상태에 대한 공정한 평가를 위해 외부 요인의 영향을 배제하는 방안의 시행과 기존 또는 신설될 도시철도 운영기관의 비용효율성을 제고하기 위해 지방공기업 또는 공단으로의 조직유형 개편의 필요성을 시사하고 있다.

Objective: To investigate the effects of dietary supplementation with different levels and molecular weights of fungal ${\beta}$-glucan on productive performances, health, carcass traits and meat quality in broilers. Methods: Two hundred and ten of one-day-old chicks with equal sex were assigned to seven experimental groups in $2{\times}4$ factorial arrangement. These groups were supplemented with (0, 10, 30, and 60 ppm) of molecular weight 1-3, 1-6 ${\beta}$-glucan (low or high). High molecular weight ${\beta}$-glucan (H: 943 kDa) was obtained from Ophiocordyceps dipterigena BCC 2073, whereas H with ${\gamma}$-Irradiation treatment was performed to achieve low molecular weight ${\beta}$-glucan (L: 8 kDa). Results: There was no statistical significance in productive performances, apparent digestibility and interaction between fixed factors along 42 days of experiment (p>0.05). A higher caecal amylase activity was present in the group that received L, while there was a dramatic decrease in H and the control groups, respectively (p<0.05). The increase of supplemental dose increased caecal amylase activity (p<0.05). Immunomodulatory effects from L was revealed by the marked increase of phagocytic activity, relative weight of thymus and bursa of fabricius (p<0.05). Similarly, the additive dose at 30 ppm provided the same results, whereas the only significant difference with supplementation at 60 ppm was an increase in phagocytic activity (p<0.05). Interestingly, villi height of broilers fed L was higher than other groups (p<0.05). The treatments did not influence haematology, blood chemistry, antibody production level against vaccination, carcass traits and meat quality (p>0.05). Conclusion: The supplementation of L at 30 ppm was suggested to achieve benefits of immune modulation without adverse effects on other parameters.

The purpose of this study is to examine the effect factors in suburban rural landscape and significant factors of apartment complex which are effective to the skyline of the sloped mountains. Also it is to propose the basic resources to preserve and improve the suburban rural landscape. The target site is Young-In, which shows the typical of rural development. Sides were take in young-In City along the roads and selected for 20 pieces. This study used questionnaire about the suburban rural landscape surveying of 45 students in Kyunghee Univ.. Also we found 2 dependent variables and 8 independent variables totally. Moreover, we have analyzed the data using descriptive statistics, correlation analysis, and multiple linear regression method between the preference and physical factors, and between the vulnerability and perceptional factors. The results are as follows: 1) With the dependent variable of preference, the areas of "green space" and "agricultural productive lands" were highly influenced in the suburban rural landscape positively, but the areas of "apartment complex" and "other buildings" were negatively effected. 2) With the dependent variable vulnerability, the area "apartment complex" and cutting numbers of the "skyline of mountainous ridge" were proved as significantly positive factors, but the length of the "skyline of mountainous ridge" turned out to be a negative factor. Although this study has the difficulty to be generalized, it can be used for planning and designing of the apartment complex in suburban rural landscapes, and it will provide the basic guideline for preserving and managing of the suburban rural landscapes.uideline for preserving and managing of the suburban rural landscapes.
