EU는 당면과제인 과잉 어획능력을 해소하기 위해 공동어업정책하 어업구조정책의 하나로 '다년도지도프로그램(Multi Annual Guidance Programmes: MAGPs)'을 시행해 왔다. 지난 1983년부터 2002년까지 시행된 MAGP는 EU의 어업구조정책의 핵심 요소이다. 이러한MAGP는 최초 EU의 공공원조계획을 위한 체제의 하나로 입안되었으며, 그 목적은 어선 톤수와 마력수에 대한 각 회원국 어선의 능력을 동결하고자 하는 것이었다. 회원국들은 $4{\sim}5$년 주기로 각 국의 어선개발에 대한 정밀한 계획을 세워야하며, 어선의 용량(총톤수와 엔진출력)과 어획노력에 관한 목표들을 달성하도록 되어 있다. 이러한 감소 목표들은 독립된 과학적 조사결과에 따라 EU 위원회에 제안되고, 공동체 선박등록부에 의거 각국의 프로그램에 대한 적정 실현여부를 감시받고 있다. 또한 각 회원국들은 매년 4월 1일까지 EU위원회에 당해 MAGP의 실현에 대한 진도보고서를 제출하는 식으로 운영되어 왔다. 현재까지 4개의 MAGP가 시행되었다. 제1세대 MAGP(1983-1986년)는 회원국들에 강제적인 것은 아닌 관계로 별다른 성과가 없었으나, 공동체 어선들간의 어획능력 증가 경쟁에 대한 제어의 표현으로 의미가 있었다. 제2세대 MAGP(1987-1991년)에서는 처음으로 진출입 제어를 위한 매우 제한된 법규정이 만들어졌으며, 제3세대 MAGP(1992-1996년)에서는 공동체 어선 감소의 실제목표를 수여하는 첫 번째 계획이었다. 그리고 이 계획은 약 15%정도의 매 우 실질적인 어획능력 감소를 이루었다. 가장 최근에 끝난 4세대 MAGP(1997-2002)는 공동어업정책의 개혁 시간을 주기 위하여 1년 연장되었으며, 이 시스템은 만약 어선의 어획구성상 감소되는 어족자원의 비율이 낮으면 그 자원을 보호하고자 하는 것이었으나, 그 성과는 매우 낮았다. 이 4세대 계획의 또 다른 중요한 혁신은 회원국이 그들의 어선의 활동규제와 크기를 결합시키거나, 또는 전적으로 표본어선의 수익성 분석을 통해 어획능력을 제거하고자 하는 것이다. 그러나 이 역시 관리와 통제의 곤란으로 별 다른 성과를 거두지 못한 것으로 평가받고 있다. 그러나 많은 어려움과 제도상 불완전함에도 불구하고 MAGP는 일정한 효과를 거둔 것으로 보고되고 있다. 즉 어획능력은 지난 20년동안 전체적으로 25% 가량 감소하였으며, 특히 오래되고 비효율적인 어선에 대한 감척으로 어획능력 감소에 기여한 것으로 평가되고 있다. 이들 프로그램은 특히 보조금을 통해 어선의 제3국 영구이전과 낡고 비효율적인 어선의 신조를 가속화시킨 것으로 보고되고 있다.

The purpose of this study was to examine the relationship between techno-stress perceived by elementary school teachers and related variables in a flipped learning environment. To achieve the purpose, the following research question have been established: First, what is the difference between techno-stress perceived by elementary school teachers? Second, what is the difference between techno-stress related variables perceived by elementary school teachers? Third, how do the TPACK, teacher effectiveness, and school environment support, perceived by elementary school teachers, affect technostress? 207 teachers at elementary school responded on a questionnaire to measure their perceived techno-stress, TPACK, teacher efficacy, and school environment support. Data were analyzed with using independent two-sample t-test, one-way ANOVA, and multiple regression analysis. The results were as follows: First, the elementary school teachers working on a leading school perceived higher techno-overload and techno-complexity more than those in ordinary school. Second, the elementary school teachers showed differences in the perception of TPACK, teacher efficacy, and school environment support according to the teacher's career, and leading school. Third, the elementary schools teachers perceived in TK, TCK, TPACK, educational support, and technology have a positive affect with techno-stress. The results are significant in that they provided data for reducing techno-stress of elementary school teachers in a flipped learning environment.

In this paper, I devise a balance-swap optimization (BSO) algorithm to solve economic load dispatch with a quadratic fuel cost function. This algorithm firstly sets initial values to $P_i{\leftarrow}P_i^{max}$, (${\Sigma}P_i^{max}$ > $P_d$) and subsequently entails two major processes: a balance process whereby a generator's power i of $_{max}\{F(P_i)-F(P_i-{\alpha})\}$, ${\alpha}=_{min}(P_i-P_i^{min})$ is balanced by $P_i{\leftarrow}P_i-{\alpha}$ until ${\Sigma}P_i=P_d$; and a swap process whereby $_{max}\{F(P_i)-F(P_i-{\beta})\}$ > $_{min}\{F(P_i+{{\beta})-F(P_j)\}$, $i{\neq}j$, ${\beta}$ = 1.0, 0.1, 0.1, 0.01, 0.001 is set at $P_i{\leftarrow}P_i-{\beta}$, $P_j{\leftarrow}P_j+{\beta}$. When applied to 15, 20, and 38-generators benchmark data, this simple algorithm has proven to consistently yield the best possible results. Moreover, this algorithm has dramatically reduced the costs for a centralized operation of 73-generators - a sum of the three benchmark cases - which could otherwise have been impossible for independent operations.

Servitization presents an innovative model to create business value in the automotive industries. This study set out to introduce a servitization model based on the rental business of the tire industry and identify determinants to affect the renewal of contracts around the service types of servitization and the characteristics of customers. Independent variables include the service types, demographics and regions, and inflow channels in 163,742 contracts by case companies in the nation in 2016~2019 with the renewal of contracts as a dependent variable. Correlations between variables were analyzed through cross-tabulation and binary logistic regression analysis. The findings show that the contract renewal rate had positive(+) relations with customized service and negative(-) ones with vehicle maintenance service. There were differences in the contract renewal rate according to such customer characteristics as gender and region, but no clear correlations were found in the age group and vehicle type(domestic/foreign). Of the inflow channels, offline channels tended to have a higher renewal rate than online channels. At open malls, contract renewal increased by 8.4 times due to contract switches at offline channels. Based on these findings, the study discussed directions for practical strategies with regard to the development of new service, implementation of customer-centric servitization, and management of sales channels according to the servitization of manufacturers.

This research suggested the traffic signal calculation model of active transit signal priority using a shockwave model. Using this signal priority timing optimization model, the shockwave area is computed under the condition of Early Green and Green Extension among active transit signal priority techniques. This study suggested the speed estimation method of backward shockwave using average travel time and intersection passing time. A shockwave area change is calculated according to signal timing change of transit signal priority. Moreover, this signal timing calculation model could determine the optimal signal priority timings to minimize intersection delay of general vehicles. A micro simulation analysis using VISSIM and its user application model ComInterface was applied. This study checked that this model could calculate the signal timings to minimize intersection delay considering saturation condition of traffic flow. In case studies using an isolated intersection, this study checked that this model could improve general vehicle delay of more over ten percentage as compared with equality reduction strategy of non-priority phases. Recently, transit priority facilities are spreading such as tram, BRT and median bus lane in Korea. This research has an important significance in that the proposed priority model is a new methodology that improve operation efficiency of signal intersection.

Recently the characteristics of those who committed serious terrorist crimes are not directly related to the direct command system of a specific terrorist organization (ex. IS) but are influenced by the political propaganda of terrorist organizations online, Terrorist crime under the loose form of the terrorist organization. Therefore, this study suggests ways to improve countermeasures against terrorism in metropolitan subways. Although it is important for the prevention of terrorism in the subway, it is important for the police officers of the subway police and the special police officers of the railway to have a physical limit to take charge of them, and after confirming that improvement measures are necessary, And pointed out the possibility of establishing independent security departments where judicial and administrative control is not feasible to grant police rights. In addition, I pointed out how to improve the safety of subways in the metropolitan area through the recruitment of core job candidates and the identity survey during the subway operation. Furthermore, it was confirmed that a special council on terrorism, which can take into consideration the characteristics of subway terrorism, such as airports and ports, is required to be established in charge of terrorism prevention under the current Anti-Terrorism Act. Finally, it is once again emphasized that the strengthening of the powers of the counterparts to terrorism must inevitably limit the basic rights of the people, so the principle of proportionality must be observed in their activities.

After 1990's, many multi-level marketing companies lave been introduced in Korea. These MLM companies operate their stores as same way as general retailing stores. The major characteristics of these MLM companys' store is that their main customers are distributors who sell the purchased merchandise to another customers. Many studies about merchandise display in general retailing stores were reported. But, there was less research about merchandise display in these special type stores such as MLM companys' stores. This paper investigates the effects of merchandise display on distributor's merchandise selection in channel flow of multi-level marketing company. For this purpose, we formulated four hypotheses about display variance in quantity, height, location, and related merchandise to analyze the effect of merchandise display methods in MLM companys' stores. The experiment had been proceeded in three stores in a MLM company for 6 weeks and the sales data were collected by POS. The methods to analyze the data were used ANOVA and T-test. Findings of this study are as follows; First, there was no effect to store sale by the interaction effect between merchandise display method and scale of store. Second, scale of store affected considerably the volume of sales of each store according to main effect analysis. Third, display variance in quantity, height, and location did not affect store sale. In the related merchandise display, however, sale in all store was increased. Fourth, in additional analysis considering merchandise display only, display variance in both height and location affected their sale in large scale store. Based on the above results, we may predict merchandise display can affect sale in MLM companys' store as well as general retailing stores. Therefore if MLM company has large scale store, it should consider merchandise display methods in its stores.

The purpose of this study is to empirically verify the effects of positive psychological capital on participation in lifelong learning as well as the mediating effect of self-directedness of adult learners in Korea. The research model was constructed using positive psychological capital as an independent variable, lifelong learning participation performance as a dependent variable, and self-directedness as a mediating variable. The results of the study are as follows: First, positive psychological capital of adult learners has a significant effect on self-directedness and participation in lifelong learning. Second, self-directedness has a significant effect on participation in lifelong learning. Third, self-directedness plays a mediating role between positive psychological capital and participation in lifelong learning. The results of this study indicate that positive learning psychology and self-directedness are important factors for participation in lifelong learning. The results of this study are expected to contribute to the development of lifelong learning systems and the development and operation of programs that can enhance positive psychological capital and self-directedness of adult learners.

This study reviewed the planning characteristics of contemporary Japanese middle school architecture on which related studies are insufficient, aiming to obtain new ideas for planning Korean middle school facilities. Fourteen case schools built after 1990s were selected and analyzed. They were divided into learning-living space and other major spaces. The planning characteristics of the case schools are summarized as follows 1) The case schools were classified into two categories, departmentalized classroom type (D type) and usual with variation type (UV type) by school system. These categories can also be the classification standard for basic architectural characteristics in learning and living space of case schools. 2) D type case schools have departmentalized classrooms, home base, media space and teacher's space for learning-living space. D type case schools are divided into 'attached-to-classroom type' and 'separate type' depending on the adjacency of the home base and departmentalized classroom. 3) UV type case schools have multipurpose space around the classroom for learning-living space and can be divided into two types, i.e., 'directly adjacent' and 'separate', depending on the connectivity to classroom of multipurpose room. 4) Specialized classrooms are designed to have the openness to the public and the own characteristics of school subjects strengthened and show the spatial differentiation with connected ancillary spaces. 5) Libraries are designed as complex zones grouped with computer labs, audio visual rooms and multipurpose halls not as a single room and as open plan not with a closed wall. 6) The gymnasium is the basic sports facility with a martial arts room and outdoor pool, which are for after-school activities as well as physical education class. 7) The terrace, balcony and outdoor stairs are frequently used architectural vocabularies as diverse outdoor spaces with a variety of functions.

Climatological informations have not been fully utilized by agricultural research and extension workers in Korea due mainly to inaccessbilty to the archived climate data. This study was initiated to improve access to historical climate data gathered from 72 weather stations of Korea Meteorological Administration for agricultural applications by using a microcomputer-based methodology. The climatological elements include daily values of average, maximum and minimum temperature, relative humidity, average and maximum wind speed, wind direction, evaporation, precipitation, sunshine duration and cloud amount. The menu-driven, user-friendly data retrieval system(CLIDAS) provides quick summaries of the data values on a daily, weekly and monthly basis and selective retrieval of weather records meeting certain user specified critical conditions. Growing degree days and potential evapotranspiration data are derived from the daily climatic data, too. Data reports can be output to the computer screen, a printer or ASCII data files. CLIDAS can be run on any IBM compatible machines with Video Graphics Array card. To run the system with the whole database, more than 50 Mb hard disk space should be available. The system can be easily upgraded for further expansion of functions due to the module-structured design.
