The purpose of this study solves both duality of construction and the economic problem of the daily laborer with activation of a construction skill human resource institute training. For the fixation of actuality institute training, the support and intervention of the public are necessary. Especially, to win young people over to construction job-site, we should analyze what they want and arrange and do information work institutionalized conditions that can satisfy their demand. Also institute training program must be reorganized to make them be acknowledged as a expert and social conditions is arranged so that they work self-conceit.

1980년대 하반기부터 한국(韓國)의 석탄산업(石炭産業)은 70년대말에서 80년대초까지와는 상이한 여건에 직면함으로써 구조적(構造的) 변화(變化)를 필요로 하고 있다. 이에 반하여 정부(政府)는 석탄정책(石炭政策)에 깊이 개입하면서도 경제여건변화(經濟與件變化)에 적절한 정책대응(政策對應)을 펴지 못하고 오히려 기업퇴출(企業退出)(exit)을 막고 산업합리화(産業合理化)를 저해함으로써 장기적으로 경제(經濟)의 효율성(效率性)을 떨어뜨리고 자원배분(資源配分)을 왜곡(歪曲)시키는 결과를 초래하였다. 본고(本稿)에서는 미래의 에너지파동(波動) 가능성(可能性)을 고려한 국내석탄정책(國內石炭政策)과 수입탄정책(輸入炭政策)에 대하여 논의하고, 개방경제하(開放經濟下)에서의 사회적(社會的) 마찰(摩擦)을 극소화하기 위한 석탄가격구조(石炭價格構造) 개선방안(改善方案)을 제시하였다. 분석결과(分析結果)에 따르면 현행(現行) 수입탄가격(輸入炭價格)은 오히려 국내탄질(國內炭質)의 저급화(低級化)를 유발시키는 저급화(低級化)를 유발시키는 왜곡현상(歪曲現象)을 초래 하고 있으므로, 앞으로는 국내탄가(國內炭價)를 석공원가기준(石公原價基準)에서 수입탄가(輸入炭價)를 기준으로 하는 결정방식으로 전환하고 수입탄가(輸入炭價)와 국내탄가(國內炭價)의 열량별(熱量別) 가격구조(價格構造)를 개선할 필요가 있다. 그리고 정부주도(政府主導)의 탄광통폐합(炭鑛統廢合)은 또다른 비효율성(非效率性)과 자원배분(資源配分)의 왜곡(歪曲)을 가져올 우려가 있으므로 가격정책(價格政策), 정부보조(政府補助) 등을 통한 간접통제방식(間接統制方式)으로 민간경제의 효율성을 유도하여 주는 것이 바람직하며, 또한 기업퇴출(企業退出)에 따른 탄광지역(炭鑛地域)의 경제활동(經濟活動) 위축(萎縮)과 실업문제(失業問題) 등에 사전적인 정책대응(政策對應) 필요하다.

This study examined the mediation effects of sensation seeking on the relationship between internal and external boredom proneness and game addiction. For this study, 567 middle school students in Kyungki and Chungcheong were included in the analysis. The results showed that both internal boredom proneness and external boredom proneness were positively correlated with game addiction. Internal boredom proneness was negatively correlated with all subscales of sensation seeking, whereas external boredom proneness was positively correlated with boredom susceptibility and disinhibition. Sensation seeking was found only to partially mediate the influence of the adolescents' external boredom proneness (independent variable) on game addiction(dependent variable). Based on these results, suggestions for game addiction intervention and future studies were mentioned.

Interaction Scale between Teachers and Children for childcare teachers (ISTC) was constructed based on the research data completed by the Ministry of Gender Equality and Family with a participation of childcare teachers and early childhood educators. The results of this study were; First, the study found that the 42 items of the ISTC were categorized into eight factors by 205 childcare teachers: a positive language and behaviors of teachers, encouragement of positive interactions among peers, offering a nap time, toilet use, emotional intervention, free play participation, an equal care of children, and meals and snack time. Second, these factors exhibited a high correlation interactively. Third, the ISTC showed a high correlation with teachers' performance scale.

최근 인간의 개입을 최소화하면서 임무를 수행할 수 있는 무인항공기에 대한 활용도가 높아지는 가운데 무인선(Uamanned Maritime Vessel) 운용에 대한 관심도 높아지고 있다. 국내에서 무인선(Uamanned Maritime Vessel) 관련 프로젝트는 오염 방제 지원, 불법조업 감시, 조난자 수색 구조 등의 감시 및 구난 방제 지원 임무와 수로조사, 해양 기상 모니터링, 적조 감시 등 해양 조사 등을 목적으로 무인선(Uamanned Maritime Vessel)을 개발하는 중이다. 무인선은 관제센터(Maritime Control Station) 또는 모선을 통하여 원격 통제로 임무를 수행하게 되며, 이를 위하여 다양한 정보가 무선통신을 통하여 유인선-무인선, 무인선-무인선, 무인선-관제센터 간에 실시간으로 제공될 것으로 예상되어진다. 본 연구에서는 ITU-R Study Group Woking Party 5B를 분석한 후, 국내 개발 예정인 무인선(Uamanned Maritime Vessel) 운용을 위하여 요구되는 통신 서비스를 구분하여 정의 및 분류하고, 이를 바탕으로 데이터 전송속도, 트래픽 이용시간, 교통량을 바탕으로 필요한 주파수 산정을 위한 기초자료를 제공하는데 목적이 있다.

IoT is network evolved one more step than Mobile or Internet based on the existing wire communication and can interconnect all people, things, and virtual space at any time, anywhere. In particular, Internet of Things technology is expected to be converged on medical service such as elderly home care, chronic disease management, and treatment, and then it also contributes to savings and service quality of in the medical field and leads the paradigm or innovation of healthcare industry. In this study, we analyzed the IoT technology and application cases of medical service based on the IoT at home and abroad.

The Internet of Things (IoT) is the interconnection of uniquely identifiable embedded computing devices within the existing Internet infrastructure. IoT is expected to offer advanced connectivity of devices, systems, and services that goes beyond machine-to-machine communications and covers a variety of protocols, domains, and applications. Time information is a critical piece in the IoT to support its requirements. This paper reviews conventional time keeping mechanisms in the Internet and presents issues to be considered for combining time and data in the IoT.

객체를 추적하는 기술은 컴퓨터 비전 분야에서 활발히 연구되고 있는 분야 중 하나이다. 그 중 고정된 단일 카메라를 이용한 객체 추적 기술은 비디오 감시(Surveillance) 등에서 활용되고 있다. 고정된 카메라 환경에서 객체를 추적하는 방법 중 배경 모델링(Background Modeling)을 이용한 방법은 간단하면서도 널리 사용되는 방법 중 하나이다. 객체의 움직임이나 특징을 분석하여 배경 모델을 생성한 후 배경 정보를 이용하여 전경을 분리하면 쉽게 객체를 추출할 수 있다. 그러나 객체의 움직임이 적은 경우 해당 영역에서의 배경 모델은 정확하게 생성될 수 없다. 배경 모델을 학습하는 동안 객체가 충분이 움직이면 이런 문제를 해결할 수 있으나 객체가 움직이기 전까지는 오류가 지속된다. 이런 문제를 해결하기 위해 본 논문에서는 인페인팅(Inpainting)을 이용하여 움직임이 적은 영역을 보정하여 정확한 배경 모델을 생성하는 방법을 제안한다. 배경 모델을 생성한 후 객체로 식별할 수 있는 후보 영역을 식별한다. 선정된 영역들 중 사용자가 객체로 판단되는 영역을 선택하여 해당 영역에 대해 인페인팅으로 화소값 및 가중치들을 보정한다. 보정된 영상으로 배경 모델링을 수행하면 움직임이 적은 영역에 대해서도 효과적으로 배경 모델을 생성 할 수 있다.

The objective of the study is to discriminate EEG(electroencephalogram) due to emotional changes. Emotion was evoked by the series of auditory stimuli which were selected from the natural sounds in the sound effect collection of compact disc. Seventeen university students participated and experienced positive or negative emotions by six auditory stimuli with intermission between stimuli. Temporal EEG ($T_3$, $T_4$, $T_5$, and $T_6$) was recorded at the same time and a subjective test was performed on the eleven point scales after the experiment. The maximum and minimum scores of the EEG among six stimuli EEG were analyzed for discrimination of emotion. The EEG signals were transformed into feature objects based on scalar intervention model coefficients. Auditory stimulus was considered as intervention variable. They were classified by Discriminant Analysis for each channel. The features showed results with the best classification accuracy of 91.2 % in $T_4$ for auditory stimuli. This study could be extended to establish an algorithm which quantifies and classifies emotions evoked by auditory stimulus using time-series models.

The purpose of this study was to investigate the typology of response to unwanted sexual request, and find the characteristics according to the types. For this purpose, 332 college female students were surveyed. As a results, two group were identified through cluster analysis: assertive type and compliant type. Compliant type had more sexual experiences, consensual unwanted sex, reasons for sexual compliance. Furthermore, compliant type had more unstable attachment, rejection sensitivity, and loneliness. Implications related with prevention and education program for the high risk compliant group were discussed and ideas for health, education, psychological experts were suggested.
