This study begins with two research interests. Firstly, there seems to be a break of research in the field of family policy in Korea which exists especially in regard to family law. Family law was originally the core of state interventions in family life, but has been neglected because of the lack of literature with comparative research methods. This shortcoming needs to be addressed. Secondly, through inquiry into the definition of family or family policy with the lens of the law, the definition of family or family policy can be correctly extended. With these two interests combined, this research tries to derive an analytical tool - maintenance community - of the law and compare some important points of the family law of Korea with those of 16 EU-countries in terms of regime classification. The method used is, firstly, to describe the subjects of family law with a focus on partnering and parenting without subjective interpretation, and secondly, to classify the countries' family-law regimes with the criteria of privacy and autonomy using cluster analysis. The results show that the countries can be classified into three clusters: Nordic (Norway and Sweden), West-Northern (Denmark, France, England, Finland, and Belgium) and Middle South (Italy, Spain, Austria, Portugal, Netherlands, Greece, Ireland, Germany, and Korea). This result can be compared to a precedent research result which showed that 21 OECD countries can be classified in three clusters according to family policy. The number of the clusters is the same as this study, but some countries belong to other clusters; for example Denmark and Finland belong to the Nordic cluster according to family policy, while they belong to the West-Northern according to family law, and Austria, Germany, and Ireland belong to the Middle-South cluster according to family law, while they belong to the Continental according to family policy. From this result we can interpret Korean family law to be in the middle range according to both criteria of privacy and autonomy like other South-European countries including some Continental countries. We can make some theoretical suggestions. The fact that both family law and family policy regimes in countries can be classified into three clusters can be interpreted to mean that there exists parallelism between family law and family policy in a broad sense. But from the fact that some countries belong to different clusters according to family law and family policy, we can say that the family policy in a country is not always consistent with family law.

Measurement of the physical properties of rocks or minerals is an important factor in determining the distribution of the underground medium as well as mineral resource investigations. Resistivity and induced polarization, which are widely used in Korea, are methods for measuring electrical properties, which are representative properties of obtaining subsurface information. In order to precisely analyze the exploration data obtained from various sites, it is important to accurately measure the material properties. Electrical properties of rock is measured using two-electrode or four-electrode method. Compared to the four-electrode method, the two-electrode method is generally used because it is very easy to contact the sample and the electrode, but there is a problem in that the impedance of the electrode and the sample is measured together. In this study, the time-domain the induced polarization effects were measured using the 2-electrode method and the 4-electrode method for artificial samples mixed with graphite and cement having induced polarization characteristics, and the results were compared. Although the 4-electrode method has difficulties in installing potential electrodes, it was confirmed that it is effective in measuring electrical properties because it can reduce the problem caused by the impedance of potential electrodes compared to the 2-electrode method.

Titanium sponge is industrially produced by the Kroll process. In order to understand the importance of the emerging smelting and recycling process, it is necessary to review the conventional production process of titanium. Therefore this paper provides a general overview of the conventional titanium manufacturing system mainly by the Kroll process. The Kroll process can be divided into four sub-processes as follows: (1) Chlorination of raw TiO₂ with coke, by the fluidized bed chlorination or molten salt chlorination (2) Magnesium reduction of TiCl₄ and vacuum distillation of MgCl₂ and Mg by reverse U-type or I-type with reduction-distillation integrated retorts (3) Electrolysis process of MgCl₂ by monopolar cells or multipolar cells to electrolyze into chlorine gas and Mg. (4) Crushing and melting process in which sponge titanium is crushed and then melted in a vacuum arc furnace or an electron beam furnace Although the apparatus and procedures have improved over the past 80 years, the Kroll process is the costly and time-consuming batch operation for the reduction of TiCl₄ and the separation of MgCl₂.

This paper proposes a human action recognition scheme to recognize nonverbal human communications automatically. Based on the principle that a human body action can be defined as a combination of multiple articulation movements, we use the method of inferencing stochastic grammars to understand each human actions. We measure and quantize each human action in 3D world-coordinate, and make two sets of 4-chain-code for xy and zy projection plane. Based on the fact that the neighboring information among articulations is an essential element to distinguish actions, we designed a new stochastic inference procedure to apply the neighboring information of hands. Our proposed scheme shows better recognition rate than that of other general stochastic inference procedures. ures.

In the current legal system, establishing aging friendly house based on health-care for the senior people over 65 seems hard to be achieved. For these reasons, this study is intended to explore the improvements in the legal system using the comparative analysis in the domestic legal systems. The related legal system is divided into two sections - healthcare system house and senior house. It is very limited only th exchange the information with medical teams. Thus, we need to investigate th concept and all the matters of health-care on the basis of cases. From these results, we are aware of the necessity of the improvements of the health-care system, and suggest plans for these problems. That is to organize the legal system, and make a new law through revising the current specific identification.

The purpose of this study is to classify the Korean precipitation regions on the basis of the characteristics of extratropical cyclonic precipitation. From now on, extratropical cyclone is called cyclone in short. By using factor analysis and Ward method in cluster analysis, precipitation regions on the basis of the characteristics of cyclonic precipitation are classified The principal data used in this study are daily precipitation records obtained from 60 weather stations of the Korea Meteorological Service during the ten years($1981{\sim}1990$), and weather charts published by the Japan Meteorological Agency. The results obtained in this study are summarized as follows: (1) In the factor analysis using 43 variables which have relation to the extratropical cyclonic precipitations, They are seven factors whose eigenvalues are above 1.0. This explains 86 percent of total amount. The first factor explains the characteristics of precipitation in the middle-west area and its contribution degree has the highest 10.9 percent. (2) According to the cluster analysis method of Ward, extratropical cyclonic precipitation regions are classified seven macro regions(such as Kyungki and North Youngseo, Youngdong and Ullungdo, Hoseo and South Youngseo, Honam and Northwest Chejudo, Southeast Chejudo, North Youngnam, and South Youngnam), 22 meso regions. (3) The characteristics of precipitation regions have relations to the path of cyclone, the direction of air inflow and the strike of mountain ranges. As the conclusion, the Central China Low brings much precipitation in the southern coast and southern area of Korea as moving to the northeastward. The North China Low moves eastward and brings much precipitation in the western area of the Taeback mountain ranges. The probability of extratropical cyclonic precipitation is the lowest in the inland of Yeongnam and the eastern coastal areas which belong to the rain shadow region. Namely, The seasonal and spatial characteristics of precipitation are closely associated with the path of cyclone and the direction of air inflow according to its passage, and the strike of mountain ranges.

오늘날의 4차산업혁명시대에서는 전통적인 대기업보다는 신속하게 사업을 추진하는 스타트업이 혁신을 주도하고 있다. 스타트업은 문제 해결에 도전하는 활동을 수행하는 프로젝트 조직으로서, 개인사업자 또는 법인 등 법적으로 인정되는 기업을 설립하는 단계인 창업과는 분명히 구분되어야 한다. 다시 말해, 스타트업 활동을 통해 일정 수준 이상의 사업성을 검증하는 준비 단계의 창업 전 스타트업과 그 결과로 창업 과정을 거친 창업 후 스타트업으로 구분해야 한다. 또한, 현재 대부분의 대학교에서는 다양한 창업 교육교과/비교과 프로그램들을 진행하고 있는데, 실제 대학생 졸업 후 취업률 대비 창업률은 비율이 극히 낮은 실정이다. 이를 감안할 때 대학생에게 창업을 목표로 하기 보다는, 도전적인 창업가 정신을 함양하고 스타트업 활동 중심의 교육을 통해 자신의 진로 적성을 찾고, 그 분야의 스타트업에의 취업을 우선 목표로 하는 교육이 스타트업의 인력난 문제를 해결한다는 측면에서 볼 때 스타트업 생태계 발전에 보다 바람직하다. 본 연구에서는 먼저 캠퍼스 스타트업 문화 확산을 위한 교육 방향으로 스타트업 관련한 '경험 확대 - 진로 선택 - 실무 체험 - 진로 실행' 단계별 지원을 제안한다. 다음으로 실제 대학교에서 개설하고 운영한 일련의 교육 프로그램으로서 진로 지도, 스타트업 활동 이해, 스타트업 활동용 디지털 리터러시, 스타트업 협력 프로젝트, 스타트업 인턴 준비 교육 과정 및 결과들을 사례로 소개한다.

This study aimed to present a policy direction that could preemptively respond to urban development by analyzing past trends and predicting future changes in urban logistics in South Korea. In particular, the scope of the study was centered on changes in the national and regional logistics master plans presented in a framework that acted on logistics policy. So, the study examined the policy changes related to urban logistics from the past to the present based on the national logistics master plan and identified a national policy base to respond to the expected changes in the logistics environment in the future. Moreover, by combining this base with the contents of the urban logistics master plan of Seoul, we proposed a logistics policy that should be continued or newly added to the urban logistics master plan. Policy proposals were also presented by dividing the future logistics environment changes into policy, social, and technological changes. In particular, the policies were proposed in urban planning (10 policies), transportation planning and ITS (8 policies), logistics technology and ITS (6 policies), and laws and systems (8 policies). Regarding policy continuity, 15 policies needed to be continued, and 17 policies were to be introduced later.
