효율적인 글로벌 SCM에 적합한 국가 간 정보 연계를 위한 인터페이스 모델 연구
박수민,안경림,박수민 (사)디지털산업정보학회 2012 디지털산업정보학회논문지 Vol.8 No.4
To look at Korea trade environment, as increasing the quantity of goods transported in North-East Asia and deepening national competitive, information-oriented logistics environment is needed. That means it is automated work process and can provide value-added service. To do this, logistics business can be efficiently handled through “Electronic Means for the Clearance of Ships” and electronically data processing. Also, by increasing the risk of international terrorism, regulation regarding to logistics security has strengthened around the advanced country, such as USA and EU, etc. or international organization, such as IMO, ISO, etc.. Furthermore, because trade and logistics environment is changing and security becomes more important in logistics area, movement or status information of goods within the port or in entry in/out becomes more and more be needed in real time. In case cross-border logistics activities, international cooperation or agreement between countries is very important. However, different opinions much happened on defining the interface. If to follow one format or type using at a specific country or organization, it was occurred to difficulty in respect of interoperability as well as additional costs or time. Therefore, this paper proposes common interface model to exchange information for the efficient global SCM for using by the output of Korea R&D project, “National Logistics Standardization System Development”.

이 논문에서는 고속철도교량 설계를 위한 활하중 모델을 통계 및 확률적 방법으로 검토하고, 하중조합의 하중계수가 주는 안전율을 분석하였다. 이 연구는 철도교량 설계기준에 대한 한계상태설계법 개발의 일환이며, 이를 위하여 경부고속철도를 운행하는 열차를 대상으로 약 한달 동안 실측하여 데이터를 수집하고 분석하였다. 이 데이터를 대상으로 교량의 설계수명에 맞도록 4가지 통계 방법들을 적용하여 설계하중을 추정하여 비교 검토하였다. 또한, 철도교량의 설계하중조합이 주는 안전율을 검토하기 위하여 신뢰도지수를 구하고 이를 분석하였다. 실측 데이터로부터 추정한 활하중효과에 대하여, 현행 고속철도 설계활하중인 표준열차하중의 0.75배를 적용한 설계활하중 효과의 크기가 최소 30~22% 더 크게 나왔다. 신뢰도분석을 통하여, 극한한계상태만을 기준으로 본다면, 추가적인 하중계수 감소의 가능성이 있음을 알 수 있다. In this paper, the live load model for the design of high-speed railway bridge is analyzed by statistic and probabilistic methods and the safety level that is given by the load factors of the load combination is analyzed. This study is a part of the development of the limit state design method for the railway bridge, and the train data collected from the Gyeongbu high-speed railway for about one month are utilized. The four different statistical methods are applied to estimate the design load to match the bridge design life and the results are compared. In order to examine the safety level that the design load combination of the railway bridge gives, the reliability indexes are determined and the results are analyzed. The load effect from the current design live load for the high-speed rail bridge which is 0.75 times of the standard train load is came out greater than at least 30-22% that from the estimated load from the measured data. If it is judged based on the ultimate limit state, there is a possibility of additional reduction of the safety factors through the reliability analysis.
A Corpus-Based Study on Metaphors of FEAR
박수민 언어과학회 2019 언어과학연구 Vol.0 No.91
This study was conducted to discover the general metaphors of FEAR in English from the synchronic point of view. To find out metaphors of FEAR, the data was retrieved from COCA, extracting the token with key word FEAR. The retrieved data was analyzed in the light of Conceptual Metaphor Theory (CMT) and classified into the types of metaphors with the statistics such as the relative frequency (FPR) and he standard error (SE). With the comparison between FPR and SE in each metaphor, the general metaphors of FEAR can be found. As a result, the general metaphors of FEAR are as follows: FEAR IS A LOCATION, FEAR IS AN OBJECT, FEAR IS A CAUSE OF MOTION, FEAR IS OVERFLOW, FEAR IS A FLUID IN THE CONTAINER, FEAR IS PHYSICAL FORCE, FEAR IS COLDNESS, FEAR IS A LIVING ORGANISM, and FEAR IS OPPONENT.
국가수준 학업성취도 평가 결과와 연계한 서답형 답안 반응 유형 분석
박수민,이광상 한국교육과정평가원 2017 교육과정평가연구 Vol.20 No.2
본 연구에서는 2015년 고등학교 국가수준 학업성취도 평가의 수학과 서답형 문항에 대한 학생 답안 반응을 유형별, 성취수준별로 분석하여 고등학교 수학과 교수·학습의 시사점을 도출하고자 하였다. 분석 대상이 되는 문항은 서답형 1번과 서답형 2번 문항으로 각각 집합과 명제, 수열 단원에서 출제 되었다. 학업성취도에 응시한 452,516명의 전체 집단의 평가 결과를 제시하고, 층화군집 방식으로 표본 추출된 7,486개의 서답형 문항 학생 답안 반응을 분석하였다. 더욱 상세한 분석을 위해 210개의 문제해결 과정 사례 조사를 시행하여 분석함으로써 답안을 유형화 하였다. 유형화 된 답안별로 학생들이 나타내고 있는 오개념을 알아보고, 학업성취도 평가 결과와 연계하여 분석함으로써 유형별 및 성취수준별 교수·학습 시사점을 도출하였다. The purpose of this study is to indicate the implications for teaching and learning high school mathematics by analyzing the students' responses on constructed response items from 2015 National Assessment of Educational Achievement(NAEA) by category and achievement level. The test items, the constructed response item 1 and 2, were set from the range of “set and proposition” and “sequence”. The results of 452,516 students who applied for the academic achievement were presented and the responses of the 7,486 constructed response items were sampled by the stratified cluster method were analyzed. For more detailed analysis, 210 cases of problem solving procedure were conducted and categorized into meaningful responses. From the results of categorizing constructed response items, the misconceptions which students had were examined and these were interpreted for teaching and learning high school mathematics.

박수민,박경원,이은비,손용우,정효훈,강태영,서종필 한국임상수의학회 2021 한국임상수의학회지 Vol.38 No.5
A 10-year-old Thoroughbred mare was referred to the Jeju National University Equine Hospital with roaring, dyspnea, and weight loss. On endoscopic examination, the horse was diagnosed with right arytenoid chondritis. Surgical treatment was selected due to the failure of a previous medical treatment. Permanent tracheostomy was performed in a standing position. The horse was restrained and tied in a proper position in the stock. The cranial parts of the 2nd to 5th tracheal cartilages were resected, as were the associated skin, mucosa, muscle, and cartilages. After the stoma was formed, external mucosa and skin were sutured using a simple interrupted method. The horse was hospitalized for 22 days receiving postoperative care including antibiotics, non-steroidal anti-inflammatory drugs, dressing as required, and was pregnant six months after the surgery. A permanent tracheostomy is thought to be effective in horses with diseases causing upper respiratory tract obstruction.
