The main objective of the research is to analyse the efficiency of bus route operation system which is comprised of Individual Operation System and Joint Operation System. While the reformation of bus route operation system has been usually considered as a service upgrade strategy for inner-city bus operation, it is comparatively difficult to have background information for policy establishment due to shortage of analytical research output. This study adopts Data Envelopment Analysis technique to estimate efficiency of 101 bus routes in Ulsan Metropolitan City which operates two types of operation systems at the same time as of 2009. The analysis results tells that the reason of inefficiency lies on pure technical factor for J.O.G., and scale factor for I.O.G.. It is also confirmed that there is bus route which inefficiently operated in I.O.G and city government needs to prepare the specific plan to upgrade pure technique efficiency before reformation of bus route operation system for successful installation.

Although the evaluation system for excavation reports has been in operation for over 10 years, there has been no research on the evaluation system. First, this study examined the changes of the evaluation system, and secondly, it analyzed the evaluation factors affecting the evaluation results. As a result of institutional analysis, the present evaluation result is being utilized in PQ, and it is suggested that the evaluation subject institution is limited to the excavation institution, which may cause disadvantages to the participating museums. We also pointed out that a small number of jury members are currently evaluating the report and therefore need to reinforce it to ease the burden of assessment. As a result of evaluation factor analysis, it was confirmed that the target score was lower but the actual effect score was higher. In addition, it suggested that the indicators should be improved because the report system, headings, natural archaeological environment, scope and method of survey, and editing and printing indicators are less influential than other indicators. In addition, we conducted a regression analysis of each group by examining the appropriateness of classification amounts according to current excavation costs. As a result of the analysis, the cost of excavation in the second and third groups in 2015 and 2016 was found to affect the score. This emphasized the need for an in-depth approach to estimating the taxonomic value of the group, which is inconsistent with the initial objective of not affecting the assessment results according to excavation costs.

Initially entering into the job market during hard times with unfavorable market institutions has a persistent, negative effect on young workers' subsequent employment. This paper analyzes hysteresis in youth unemployment by using a composite fixed-effect panel data model. Data sets for the age-cohort unemployment rate and for labor market institutions are constructed from OECD statistics from 21 advanced economies, including Korea, from 1985 to 2017, and are then readjusted to match with the peculiarities of the Korean market. In Korea, with a less-aggressive stance on active labor market policy spending, a male worker who experiences a one percentage point higher youth unemployment rate when he was 20- to 29-years-old has a 0.146 percentage point higher unemployment rate at the ages of 30-to 34-years-old and a 0.035 percentage point higher unemployment rate at the age of 35- to 39-years-old. These figures are larger than those in most countries that have more aggressive spending schemes. These findings point out that hysteresis in the Korean labor market can be mitigated by expanding active labor market policy spending more aggressively and more effectively.

Standard Estimating System, which can be used for estimating a construction cost, has been pointed out having some problems such as non-reflecting a variety of construction environments and site conditions, non-adapting new technologies and methods since it was established in 1970. For solving these problems, the Korean Institute of Construction Technology(KICT) has chosen organizations for amending Standard Estimating System. However they have had many mistakes in the process of amending works because of non-establishing amending process and absence of the depreciation measurement method. This research derived the necessity to improve the amending process of the Standard Estimating System, and presented the detailed amending process and the performing method in the each process. Furthermore, this research proposed the depreciation measurement method available for the construction industry by means of analyzing researches that performed in the manufacturing industry and the measurement method for depreciation of general accounts.

Currently, the domestic electricity rates for houses are charged by applying a progressive level according to monthly electricity usage. Electricity rates rise sharply wWhen the amount of electricity used is large, electricity rates rise sharply. The standardized electricity rate progressive system has limitations in that it lacks consideration of the consumers' power usage patterns and limits consumers' their options. Accordingly, the Ministry of Trade, Industry and Energy and the Korea Electric Power Corporation have been demonstrating the basis of a rate system for housing, which is a method of charging electricity according to the amount of electricity used by season and time. In this paper, 10 electricity usage patterns were derived through from AMI data analysis for 5 five years of 362 apartment complexes located in metropolitan cities. The patterns were, and then applied to the existing domestic electricity rate and time-by-time rates applied to demonstrations, and by time-by-time rates in the US and Australia. The effect of the optional rate by pattern was compared and analyzed. As a result, it was confirmed that benefits occurred in five5 patterns compared to existing rate plans, and the electricity rates increased in 5 five patterns, and t. This phenomenon shows the same phenomenon withis the same as the overseas rates, including domestic rates being demonstrated.

This study was performed to investigate health care system satisfaction and reform need using the data from the '2019 Health Care Experience Survey'. For 8,349 data with experience in medical use, health care system satisfaction and reform need level was analyzed by t-testing and ANOVA by characteristics of the study subjects, and multiple regression was conducted. Research has shown that health care users' recognition of the health care system is relatively low compared to reliability and satisfaction. It is necessary to promote policies and health care systems for senior citizens, low education levels. Since the reliability has the biggest impact on the satisfaction of the health care system, government should establish policies that they can trust, and in the process, they should gather opinions from the public and secure credibility through social consensus. Medical users were sympathetic to the need for reforms in the health care system, and felt the need to support vulnerable areas and vulnerable groups the most.

The purpose of this study is to understand the experiences and perspectives of the self-reliance program participants through a longitudinal qualitative study from 2006 to 2012. Based on Grounded theory approach, it examines how participants managed their lives up to now status. Through open-coding process, 181 meanings were identified. Paradigm model shows that the goal of the self-reliance program can be viewed as causal condition. However, contextual factors such as poverty experiences and child-support affected the self-reliance program participants to adapt and stay in the program rather than actively participate in the market. The finding shows that the meaning of self-reliance are differently understood by policy makers and self-reliance program participants.

Supercritical Fluid Chromatography(SFC) has been developed as an analytical technique for the compounds that is difficult to analyze by conventional chromatography. Since supercritical fluid $CO_2$ is difficult to elute solutes with high polarity, modified supercritical $CO_2$, was used as a mobile phase. In conventional method, silica column which is saturated with modifier was used. However, with this method, we can not control the quantity of modifier. In this paper, we developed a new method which can control quantity of modifier mixed in supercritical fluid $CO_2$. The quantity of $H_2O$ mixed was measured with amperometric microsensor which was made by perflurosulfonate ionomer(PFSI) film. we have also obtained a good supercritical fluid chromatogram of PAH mixture by use of a modifier composition programming method.

For the purposes of this research, a corpus of words was created from the English textbooks of the "First Middle School" for the gifted in North Korea, and using the corpus, their linguistic characteristics were analyzed. Although there have been many studies that identified the traits of English textbooks in the North Korea's general middle school, not much focus has been placed on the English textbooks used at North Korea's First Middle School. Initially, the structure of English textbooks of the first, second, fourth, and sixth grades that had been procured from the Information Center on North Korea was reviewed, after which their corpus was created. Then, by using Wordsmith Tools 7.0, linguistic properties and high frequency content words appeared in the English textbook of the first grade were analyzed specifically. Basic statistical data gathered indicated that while the number of vocabulary did not increase as students progress through the grades, the words used tended to diversify incrementally. In the mean time, a distribution of the high frequency content words by grade illustrated that a big difference was found between the content words used in the English texts of each grade, and it was a subject matter of the texts that determined such difference.

The number of foreign qualification holders has been on the rise due to the globalization and the development of transportation. As in other developed nations, Korea faces the growing demand for foreign higher education recognition (FHER) since the number of foreign students and migrant workers has reached about one million recently. Unfortunately, there has been no FHER system in Korea so far. In this context, this study has compared the cases of Australia and New Zealand. The results reveal that these two countries are similar in that both of them have developed their own FHER system in order to attract highly qualified foreign workers and students. However, they are different in terms of the implementation of the FHER system and the development of the FHER database. Besides, the cases of both countries shed light on the key issues related to the FHER. Taken together, they provide significant implications for the Korean government which has to develop its own FHER system in the near future.
