This paper analyzes a social insurance system that integrates unemployment insurance with a pension program, allowing workers to borrow against their future wage income to finance consumption during an unemployment episode and thus improving their search incentives while reducing risks. This paper identifies the conditions under which the integration improves welfare and the factors which determine the optimal degree of integration. A fully integrated system is one in which no reliance is placed at all on a separate tax-funded unemployment insurance program. We show that when the duration of unemployment is very short compared to the period of employment or retirement, the optimal system involves an exclusive reliance on pension-funded self-insurance. This system imposes a negligible risk burden for workers while avoiding attenuating search incentives. We also argue that a joint integration of several social insurance programs with a pension program through an individual account is desirable unless the risks are perfectly correlated to each other.

This study is designed to develop a certification system for non-formal environmental education educators as part of efforts to nurture non-formal environmental education educators, increase public trust in non-formal environmental education educators and secure structure and sustainability of non-formal environmental education. The job of non-formal environmental education educators-distant from technical expertise functions that are dealt with by existing certification system - belongs to education and service industry, And the certification system I try to develop is different from existing exclusive certification system based on written tests. It is rather an authentication system based on capability development. So its components are somewhat different from those of existing certification system. However, I also tried to ensure that the system should include components which were supposed to be part of basic certification system. The certification system for non-formal environmental education educators in the study is focused on developing a framework for basic certification system. Therefore, I believe that follow up studies may be needed to address execution, i.e., specific evaluation criteria to select organizations in charge of certification system and education course/program respectively, criteria to select instructors who will lead training course/program and decision on whether experiences as eco-guide or nature experience guide should be recognized as experiences for non-formal environmental education educator etc.

Taekwondo, Korean traditional martial art as one of the ten Korean cultural symbols, has acquired a reputation for introducing and globalizing Korean culture together with its standing as official Olympic Game in 2000, Sydney, Australia. Nevertheless the World Taekwondo Headquarters, Kukkiwon, which is an exclusive Taekwondo institution only accommodates for three thousand persons. Considering the worldwide reputation of Taekwondo, the scale of Kukkiwon leaves a big supply problem. This study therefore suggests the plan to design Taekwondo park that playa major role of Taekwondo development in the 21st century and represent the cultural heartland of Taekwondo. The study considers four points. The points are as follows: 1) Necessary programs drawn by analyzing and assessing Muju city as a site for Taekwondo park, then a survey conducted for potential visitors to a Taekwondo park. Under the theme of "A World Cultural Heritage Upon Our Own Lives", the park plan intends to become a shrine of Taekwondo as well as a big tourist attraction. 2) Programs are appropriate for the terms of the investment under the auspices of government, by considering potential visits and the site conditions. 3) The meaning of Taekwondo and its history should be reflected in the space distribution and facilities allotment. Three meaningful zones: symbolic zone, training zone and culture zone are considered in planning program and space distribution. 4) The plan also intends to harmonize with local development by groping Muju city's uplifting, not only designs a Taekwondo park.

This study was a cross-sectional descriptive study that analyzed the effect of quality of life on marriage views in college students. The purpose of this study was to identify the relationship between quality of life and marriage view. The study targets were 195 male and female university students aged between 20 and 25. The data collection was done only by those who voluntarily agreed to the study using online questionnaires, and the data collection period was from October 1 to October 30, 2020. Data analysis was performed using SPSS 18.0 for frequency analysis, χ2 analysis, Pearson correction, t-test, and simple regression analysis. The result of the study that men had higher conservative marriage view (M=3.22, SD=.716) than women (M=2.21, SD=.903, p<0.01), women had higher active marriages (M=3.94, SD=.955) than men (M=3.41, SD=.933, p<0.01), and women had higher exclusive marriage views (M=3.94, SD=.955) than men (M=3.41, SD=.933, p<0.01). And people with high quality of life positively influenced romantic marriage view (R2=.029, p<0.05), but negatively affected passive marriage view (R2=.029, p<0.05) and conservative marriage view (R2=.034, p<0.05). Based on the results of this study, a program is needed to create a positive marriage view for the married age group, create an environment for married people to positively engage in social and economic activities, and propose a program for creating healthy family relationships.

In an attempt to isolate novel molecules that may play a regulatory role in adipocyte differentiation, we devised an experimental strategy to identify adipose tissue-specific genes by modifying cDNA microarray technique. We used genefilter membranes containing approximately 15,000 rat non-redundant EST clones of which 4,000 EST were representative clones of known genes and 11,000 ESTs were uncharacterized clones. A series of hybridization of genefilter membranes with cDNA probes prepared from various rat tissues and nucleic acids sequence analysis allowed us to identify two adipose-tissue specific genes, adipocyte-specific secretory factor (ADSF) and H-rev107. Verification of tissue-specific expression patterns of these two genes by Northern blot analysis showed that ADSF mRNA is exclusive expressed in adipose tissue and the H-rev107 mRNA is predominantly expressed in adipose tissue. Further analysis of gene expression of ADSF and H-rev107 during 3T3-L1 adipocyte differentiation revealed that the ADSF and H-rev107 gene expression patterns are closely associated with the adipocyte differentiation program, indicating their possible role in the regulation of adipose tissue development. Overall, we demonstrated an application of modified cDNA microarray technique in molecular cloning, resulting in identification of two novel adipose tissue-specific genes. This technique will also be used as a useful tool in identifying novel genes expressed in a tissue-specific manner.

This study intends to understand deeply the higher education evaluation accreditation system in Taiwan. Taiwan established newly the Higher Education Evaluation & Accreditation Council in 2005, an independent organization with the exclusive responsibility to execute evaluation. Three kinds of evaluation have been accomplished, including University Program Evaluation which assesses whole university management, Academic Fields Evaluation and Performance Evaluation which compare the superiority and inferiority among universities. The Accreditation system is applied only to Academic Fields Evaluation. For evaluation, each university presents a self-evaluation report, undergoes an visiting evaluation, makes out an evaluation report and lastly is notified of the result. The evaluation is divided into three results : pass, waiting observation and non-pass. According to an announcement in June 2008, the rate of non-pass universities reached the 15.7%. The non-pass universities are supposed to receive the disadvantaged in the admission number limit and take the following evaluation in the following year. Debates still exists concerning the eliminatory nature of the system and the announcement of achievement rankings through evaluation results. Other problems include the improvement of quality of evaluation committee members and the irrational evaluation standards. These problems will be meaningful for the development of the korean higher evaluation system.

The purpose of this study is to solve the problems of radio frequency bandwidth frequency depletion, confusion possibilities, and security that are in current wireless communications systems, and to confirm the possibility of applying those solutions for the next generation network. To solve the problems of the current wireless communications system, a visible light communications system for power line communication (PLC) via 8-bit microcontroller is created and the capacity is analyzed. The exclusive PLC chip APLC-485MA, an 8-bit ATmega16 microcontroller, high brightness 5pi light emitting diodes (LEDs), and the LLS08-A1 visible light-receiving sensor were used for the transmitter and receiver. The performance was analyzed using a designed program and an oscilloscope. The voltage change was measured as a function of distance from 10-50 cm. Blue LEDs showed the best performance among the measured LED types, with 0.47 V of voltage loss, but for a distance over 50 cm, precise data was not easy to obtain due to the weak light. To overcome these types of problems, specific values such as the changing conditions and efficiency value relevant to the light emitting parts and the visible light-receiving sensor should be calculated, and continuous study and improvements should also be realized for better communication conditions.

Generally circuit devices of low voltage are as follows, ICCB, PCB and MCCB. Among them, MCCB is typically used because it has superior characteristics which fuses do not possess, such as safety, controllability and ability to collaborate with other devices. The MCCB plays vital role, it has to trip instantaneously when the fault is occurred as well as it must have high insulation capacity. Therefore in order to enhance the breaking capacity, the study of contact construction, contact tip and link are necessary. This paper shows dynamic modeling of mechanism part of MCCB using an exclusive analysis program, and embodies the research of improvement of mechanism performance.

PID(Proportional, Integral, Derivative) controller is one of the most used process controllers in nuclear power plants. The optimized parameter setting of process controller contributes to the stable operation and efficiency in the operating nuclear power plants. PID parameter setting is tuned when new process control system is established or process control system is changed. It is a burdensome work for I&C(Instrument and Control) engineers to tune the PID controller because it requires a lot of experience and knowledge. When the plant is in operation, inadequate PID parameter setting can be the cause of the unstable process of the plant. Therefore the results of PID parameter setting should be compared, simulated, verified and finally optimized. The practical PID tuning methods used in process controller are tuning operation calculation(Ziegler-Nicholes, Minimum TIAE, Lambda, IMC), exclusive tuning program based on computer and Matlab application. This paper introduces the various tuning methods and suggests an optimized PID tuning process in the operating nuclear power plants.
