A newly developed heuristic algorithm, Harmony Search, is applied to the parameter calibration problem of the nonlinear Muskingum model. The Harmony Search could, mimicking the improvisation of music players, find better parameter values for in the nonlinear Muskingum model than five other methods including another heuristic method, genetic algorithm, in the aspect of SSQ (the sum of the square of the deviations between the observed and routed outflows) as well as in the aspects of SAD (the sum of the absolute value of the deviations), DPO (deviations of peak of routed and actual flows) and DPOT (deviations of peak time of rented and actual outflow). Harmony Search also has the advantage that it does not require the process of assuming the initial values of design parameters. The sensitivity analysis of Harmony Memory Considering Rate showed that relatively large values of Harmony Memory Considering Rate makes the Harmony Search converse to a better solution.

The Internet was designed for machines, not humans, and hence, nobody owns a digital identity. Instead, a digital identity is rented from a website and an application. This lack of unique and secure digital identities has resulted in confusion in the online/cyber world. Digital identities pose one of the oldest and most difficult problems with regard to the Internet. There is still no way to use digital credentials to prove, own, and control an online identity, namely a self-sovereign identity, in the same manner we do in the offline world, particularly without a trusted third party. This article discusses the current open standards for digital identities, proposes solutions pertaining to digital identities in the future, and introduces the concept of a blockchain-based self-sovereign digital identity without the need of trusted third parties.

In order to maintain the existence of a university in the era of infinite competition, it is actively promoting the establishment of a school dormitory, one of the welfare facilities, as a way to attract students who want to enter the university. In the past, university dormitories were built by the university and managed and operated on themselves, but recently, due to the poor financial situation of the university, university dormitories promoted BTL method that private construction company built dormitories and rented them for a certain period of time to manage and operate. J University has dormitories managed and operated by itself and dormitories managed and operated by entrusting the private sector. User satisfaction surveys are conducted on two dormitory facilities with different management and operation organizations, and the contents of the survey are compared and analyzed. This study is expected to be used as basic data when planning a dormitory remodeling project or a new dormitory establishment project in the future.

임대주택단지는 저소득 계층에게 주거의 안정적 공급을 위해 조성되는 단지로서 주거복지측면에서 우리사회에서 갖는 의미가 크며, 지속적인 논란과 관심의 대상이 되어 왔으며, 저소득계층의 거주환경에 대한 관심 등으로 이슈가 되어 왔다. 또한 임대주택단지는 주거사와 궤를 같이하며 발전해 왔으나 저소득계층의 삶의 질 측면에서는 일반 공급 주거와 상당한 차이를 보이며, 이는 궁극적으로 소득계층에 따른 누려야 하는 삶의 질에 대한 권리문제로 논란이 지속되고 있다. 본 연구를 위해 총 6곳의 임대주택단지 답사를 실시하였으며, 시설이용성과 물리적 환경에 대한 조사를 실시하였다. 시설의 이용은 단지의 물리적 환경에 대한 배치계획에 영향을 받으며, 특히 단지의 주진입과 주변 단지와의 관계 등에 영향을 받고 있다. 또한 커뮤니티 공간의 디자인과 시설계획의 정도에 따라 이용자의 이용성에 영향을 미치는 것으로 파악되었으며, 커뮤니티 시설의 복합적 기능 확보를 통해 이용자 요구를 수용할 필요성을 확인하였다.

The purpose of this study is to identify the current status of the working poor and the factors that are influential to the working poor among echo boomers. This study is a secondary analysis using the data from the 7th analysis of the 2012 Korea Welfare Panel Survey, conducted by Korea Institute for Health and Social Affairs. This analysis considered Korean echo boomers born between 1979 and 1985. In our final analysis, we used 1,226 echo boomers who had the ability to work. For the analysis, the SAS/PC statistical program ver. 9.3 was utilized. The research findings are as follows; Firstly, of the working poor among the echo boomers, only 22% were in the state of poverty. Secondly, more echo boomers living in a metropolitan city, city, gun/urban-rural area and district than those in the Seoul were categorized as among the working poor; the same was true for those who lived in a free house than in a leased room or a room that was rented by the month. Thirdly, more echo boomers whose education level was high school graduate or less rather than college graduate or less or university graduate or more were categorized as among the working poor; this was also true for echo boomers whose employment type was temporary employment, self-employment, or unemployment rather than a full-time job.

The purpose of the study for this thesis is to look into the status and issues of government office buildings since the self-government policy through comparing and analyzing government office buildings, between domestically and to provide improvement plans of the citizen cultural space and with the self-government budget, enhance the utility and efficiency of the government office buildings and to take a role of a reference in the future when citizen cultural space is formed in the government office buildings. As the result of the study, the space planning characteristics of government office building's citizen cultural space in terms of cultural administration is as follows. First, percentage of room to strengthen the sense of community is small. Therefore, the place where residents can argue there is a need. Second, it is necessary to expand the venue and art collection that are missing in public government buildings. Third, since the lecture room for lack of civic education, it should be taken into account when making cultural space for the citizens. Fourth, thread observatory and souvenir shops, providing information is not enough, it is to be further expanded. Fifth, rented facility for public is hall be provided with a diversity.

The purpose of this study is to inverstigate the need of child care services and child care programs for the working class mothers. We surveyed four Industrial complex (in Seoul, Incheon, Pusan, Ulsan) to collect data. The samples were 282 mothers (Seoul: 95, Incheon: 54, Ulsan: 62, Pusan: 71). The mothers had children under six years of age and they worked at factory for 11 hours. They (65%) rented houses with 1-2 rooms. Their income was not enought to support their family. They were never supported by social network, so they had to work at factory and they need child care services. The mothers had many difficulties of child rearing and early childhood education. They wanted perfect day care programs. They expected it as followings: (1) Day care center placed at factory or near home. (2) The administrater is goverment or employer. (3) It is managed a full time system. (4) It is center-based day care or industrical day care. (5) They share day care expense with employer or goverment. (6) Day care expenses is 35,000 won in case of full time system, 25,000 won in case of half-time system. They desited highly qualifed day care programs, but they would not expense highly cost. So we suggest that goverment and factory employers support the working mothers.
