Currently, in the field of community service, it is expected that the demand will further increase in the future by enabling the form of providing various types of services. However, the local community service investment project is an abstract Although the structure for fair competition was created by introducing a market mechanism derived from the action or principle of psychology that affects human behavior in the field, systematic management and monitoring of the quality of social services is insufficient. The purpose of this study is to find out the relationship between service selection factors and service quality in order to improve the quality of social services in the consumer's way to meet these environmental needs, and to utilize the research results for quality improvement. The research model to be used in this paper measures the five element areas of service satisfaction such as reliability, responsiveness, empathy, certainty, and tangibility, which are used to measure the quality of local community service investment projects. In addition, we are various strategic implications that can induce the quality improvement of local community service investment projects are presented by finding the main factors of the four research hypotheses of this study and utilizing the results.

This study attempted to verify and examine the effect of screen golf course service quality on reuse. A total of 300 copies were distributed, and a total of 247 copies were used for analysis, excluding 53 questionnaires with poor responses or many missing questions. Based on these results, the following implications were derived. First, screen golf course users were mainly used by friends, acquaintances, and social groups, and information was obtained through human and Internet, and empathy and reliability among service quality affected the reuse of screen golf courses. When users experience high-quality services, they have high satisfaction and high service quality, and they can increase the probability of forming loyalty and recommending and promoting them to people around them. However, experiencing poor quality services can disappoint customers and leave negative comments on people around them, which reduces the likelihood of reuse. Therefore, in order to increase the reuse of golf courses, quality management, customer opinions and feedback must be accepted, and problems must be dealt with quickly to improve the quality of services and provide services that satisfy customers. Second, although the types, responsiveness, and certainty of sub-factors of screen golf course service quality were not significant in this study, management strategies should be used to increase survival in the highly competitive screen golf industry and reuse them by providing differentiated services.

본 연구는 최근의 사회조사와 선거자료를 이용하여 한국사회의 지역주의의 특징을 살펴보고자 한다. 첫째, 최근의 선거결과에 보이는 지역주의적 투표는 지역간 사회적 거리를 잘 보여주고 있다. 둘째, 이러한 사회적 거리는 '편견과 차별'의 형태로 다양한 일상생활에서 존재하고 있다. 많은 사람들은 이러한 편견을 믿고 있으며, 편견에 의한 지역적 차별을 경험하고 있다. 특히 이러한 경험은 특정지역(호남)과 관련되어 있다. 셋째, 이러한 정치적 측면(지역주의적 투표)과 사회적 측면(지역간 편견)을 선거제도와 연결하여 살펴봄으로써, 앞으로 한국사회의 정치제도의 변화에 대한 전망을 할 수 있다. 연구의 잠재적인 가정은 선거에 있어서 지역적인 투표가 무조건 '나쁜' 것만은 아니라는 것이다. 한국 정치에서 나타나는 지도자나 이데올로기의 편향은 많은 사람들로 하여금 투표나 선거에서 출신지를 중요한 요소로 삼게 하였다. 이러한 요소는 쉽게 사라지지는 않을 것이며, 앞으로 선거제도의 변화에 중요한 역할을 할 것이다. 이러한 예측은 세 가지 중요한 요소에 근거하고 있다. 첫째, 유권자들의 지역주의에 대한 믿음과 예측은 쉽게 사라지지 않을 것이다. 둘째, 정치지도자들은 지역주의를 선거와 관련한 자신의 이익을 위해서 최대한 이용할 것이다. 셋째, 지역주의에 근거한 유권자들의 성향은 최근 선거와 투표에서 더욱 강화되고 있다. 정치엘리트들이 지역적인 기반을 중심으로 결합하려는 경향이 강해지고 있다. 이러한 경향은 이들 정치엘리트 사이의 내각중심제에 대한 선호도와 지역당의 출현 가능성을 증가시킬 것이다.도 설치행위의 처분성과 관련하여 횡단보도의 설치행위와 같은 일반적인 명령을 항고소송의 대상으로 할 필요성이 존재한다면 이른바 독일에서의 일반처분이라는 개념을 무리하게 받아들여 이를 행정행위의 한 유형으로 한다거나 우리 판례와 같이 "직접적이고 구체적인 법적 효과"를 미치는 명령이라는 명확치 않은 기준에 의하여 처분성을 인정하기보다는 일반적인 명령과 개별적인 행정행위를 구분하고 명령에 대하여도 취소소송의 대상으로 삼도록 하는 보다 명확하고 일관성 있는 논의전개를 제안하였다.수 있었다.로 첨가하여 48시간 배양한 후 암항원 유전자 발현성을 측정한 결과 세포주에 따라 다소 차이는 있으나 대개 0.2 uM농도에서도 유전자 발현이 유도되었으며 1, 5 uM농도에서 매우 강하게 유도되었다. ADC 처리가 페암세포주의 MHC와 B7 발현을 증가시키는가를 알아보기 위해 1 uM 농도의 ADC를 72시간 처치한 후 FACS 분석을 실시한 결과 4개의 페암세포주에서 MHC 및 B7분자의 발현은 유도되지 않았다. 또 ADC농도가 세포성장에 미치는 영향을 알아보기 위하여 ADC를 0.2, 1, 5 uM농도로 96시간 처치 후 세포수를 측정하여 상대성장지수를 알아본 결과 ADC 처치 농도가 증가함에 따라 세포의 성장은 매우 감소하였다. 결론: 폐암세포주에서 ADC처치는 MAGE, GAGE 및 NY-ESO-1과 같은 세포독성 T 림프구 반응을 유도할 수 있는 암항원의 발현을 증가시킬 수 있으며, ADC의 세포독성과 항원 발현 유발시간을 분석할 때 1 uM 농도에서 48시간 처치한 후 ADC가 없는 배지에서

In this paper we describe contents and results on running test for ATP on-board equipment, which has propelled as one of the research projects, so called, "Reliability assessment and operation technology development for Korean-type tilting trains" in order to ensure the safety and operation efficiency of tilting trains. We developed tilting trains for the speed-up of conventional lines and for the passenger service improvement where the KTX is not available. And we made progress the operation trial test in the 120,000 km distance with the use of ATS equipment, used in existing lines, for the purpose of the reliability assessment of the developed tilting trains. We decided to accelerate the speed for more than 200km/h with respect to the 6 existing lines including Jungang-line and Chungbuk-line where KTX has not operated. According to this decision, Train control system is to be changed from ATS to ATP. We should have installed an ATP on-board unit in tilting trains and verified the operational suitability, therefore we installed the same ATP on-board unit on tilting trains as that used in the ATP construction project on Gyeongbu-line and Honam-line, and verified that the function and performance of the installed ATP on-board unit conformed to the tilting trains operation.

Improvement of productivity in ethanol fermentation was attempted using a hollow fiber bioreactor (HFR) where Saccharomyces cerevisiac var. ellipsoideus cells were recycled to achieve a high yeast concentration. Industrial wort was used as the fermentation media without supplying any additional nutrients. The performances in hollow fiber recycle reactor (HFR) were compared with those of batch and continuous cultures. In a continuous culture with 11$^{\circ}$P and 15$^{\circ}$P wort media final ethanol concentrations were 4.71% and 5.82% (v/v) and yields 86.2% and 78.6% respectively when the dilution rate (D) was 0.1 h$^{-1}$, in contrast, the ethanol concentration and productivity in HFR were 7.64%(v/v) and 6.1g/l/h at D=0.1h$^{-1}$ with 15$^{\circ}$P media. When the dilution rate was increased to 0.2 h$^{-1}$, the concentration and the Productivity were 7.62% (v/v) and 12.2g/l/h. At D=0.3h$^{-1}$ the sugar was completely consumed and the productivity was 18.1g/l/h. This correponds to 4 times that in continuous system and 16.3 times that in the batch system performed in comparable conditions.

This study attempts to explore the activities and performance of industry-academic cooperation with the perspective of the firm that has not been systematically addressed in the previous research. To do this, a survey of university family companies across the country was conducted to draw factors that influence the competencies of firms and universities on the performance of industry-academic cooperation and to compare differences by region. The main results of the study are as follows. First, it was found that the knowledge and technologies that universities retain and the active participation of companies in the activities of university-academic cooperation were the most important contributors to the corporate achievements in industry-academic cooperation. Second, when divided into the Seoul metropolitan area and non-capital area, it was found that there was a difference in the capabilities and performance of industry-academic cooperation between the two regions. Third, it was found that there were significant differences in the capabilities and performance of industry-academic cooperation in five areas. These findings suggest that industry-academic cooperation projects specialized for each region is necessary to enhance the effectiveness of industry-academic cooperation.

The development of the European Railway Traffic Management System (ERTMS) began in 1989 as part of the European Union policy to establish a unified and interoperable railway route in Europe. It is a trend that ERTMS/ETCS(European Train Control System) is becoming an international standard in the railway signaling system. As the solution to this situation, the domestic railway signaling field is also at a time when it is more necessary to develop the technology of the train control system considering interoperability. The European Railway Agency (ERA) has proposed B3R2 (Baseline 3 Release 2) for new ETCS-equipped trains after 2020.12.31. In Korea, Baseline 2.2.0 to 2.3.0d on Gyeongbu Line, Honam Line, Jeolla Line, and Gyeongchun Line was installed and now is under operating. As the Baseline upgrade continues, technical considerations and economic considerations are an occurring trend. In this paper, we analyzed the main functions and compatibility of the currently distributed European standard ERTMS/ETCS Baseline 3 and presented a plan to apply the domestic KTCS(Korean Train Control System) Baseline in the near future.
