This study was performed to review applying the case management to the occupational health nursing as a cost-effective way for injured workers. The case management for injured workers is a comprehensive management system, which is composed of planning and implementing in cooperation with employee, employee' family, medical service provider team, employer and case manager, to provide high quality health services to employee and their family. The case management process for injured workers is similar to the nursing process. It thus appears that the occupational health nurse is best personnel to perform the role of case manager for injured workers in workplace. As a case manager in workplace. the occupational health nurse would be expected to get both knowledge and experiences, to get trusted from the employee and employer, and to expand professional domain in changing health care environment.

The purpose of this study was to assess the quality of the case reports in the Journal of Acupuncture Research (JAR). All case reports were retrieved from November 2017 to June 2020. There were 19 case reports included in this assessment based on the case report (CARE) guidelines and case report and standards for reporting interventions in clinical trials of acupuncture (STRICTA) guidelines. The overall quality of reporting was relatively high (83.08% on Case Report guidelines and 77.78% on Standards for Reporting Interventions in Clinical Trials of Acupuncture guidelines), but several crucial items remained substantially underreported, such as identifying as a case report (keywords), patient information and perspective, clinical findings, diagnostic assessment, and intervention information. In 18 out of 19 included case reports of acupuncture-related interventions, several items remained considerably underreported such as acupuncture regimen variation, depth of needle insertion, response sought, and experience of acupuncturists. In the classification by disease, condition, or syndrome, 13 out of 19 included case reports were for musculoskeletal disorders (68.4%), which is the main clinical medical field of Korean medicine services. The results of this study may help develop more appropriate reporting guidelines for case reports published in JAR.

The aim of this research is the development of a CAPP system which can use the old experience of process planning to generate a process plan for a new part and learn from its own experience using the concept of stratified case-based reasoning(CBR). A process plan is determined through the hierarchical process planning procedure that is based on the hierarchical feature structure of a part. Each part and case have their own multiple abstractions that are determined by the feature structure of the part. Retrieving the case in stratified case-based process planning is accomplished by retrieving the abstraction that is most similar to the input part abstraction in each abstraction level of the case-base. A new process plan is made by the adaptation that translates the old case's process plan into the process plan of a new part. Operations, machines and tools, setups and operation sequence in each setup are determined in the adaptation of abstraction using some algorithms and the reasoning based on knowledge-base. By saving a new part and its process plan as a case, the system can use this new case in the future to generate a process plan of a similar part. That is, the system can learn its own experience of process planning. A new case is stored by adding the new abstractions that are required to save as the new abstraction to the existing abstractions in the case-base.

An ICSID award on Lone Star case has been rendered finally on August 31st, 2022 after almost ten years since the Lone Star Funds submitted the request for arbitration against the Republic of Korea in 2012. The Lone Star case is the first investor-state dispute settlement(ISDS) case brought against Korea, and this case, also known as "eat and run" case, has given rise to heated debates for years. Moreover, as the ICSID tribunal has ordered Korea to pay the Lone Star Funds the sum of USD 216.5 million plus interest in the award, this case has become once again the subject of controversy. Any arguments and evidence submitted by the parties in dispute have not been disclosed until recently, however, as the memorials and the award are now open to the public, it has become possible to realize the assertions of each party and the decisions of the tribunal in detail. Therefore, this paper aims at analyzing the main issues of the Lone Star case with a focus on the ICSID award. By examining the substantive and procedural issues of the case one after the other, it might be able to understand the whole picture of the case and prepare for the remaining procedures of this case and other upcoming cases as well.

본 연구는 도심의 열환경 개선 및 건물에너지저감 효과가 입증된 벽면녹화 중 기존 건물에 적용 가능한 패널형 벽면녹화 식재기반 유형에 따른 건물에너지 저감 성능을 분석하고자 하였다. 식재기반 유형은 총 4가지 유형으로 하였으며, Case A는 벽면녹화가 미적용된 유형으로 콘크리트 + 단열재로 구성하였다. Case B는 식재층 + 무기다공성블록 + 콘크리트 + 단열재로 구성하였으며, Case C는 식재층 + 코코피트블록 + 콘크리트 + 단열재로 구성하였다. Case D는 식재층 + 마사토블록 + 콘크리트 + 단열재로 구성하였다. 분석항목으로는 열전도율, 열관류율, 건물에너지시뮬레이션을 실시하였다. 식재기반 유형별 열전도율은 Case C(0.053W/mK) > Case B(0.1W/mK) > Case D(0.17W/mK)의 순이었다. 에너지시뮬레이션 결과 중 단위면적당 냉방피크부하저감은 미적용인 Case A 대비 Case C(1.19%) > Case B(1.14%) > Case D(1.01%)이며, 난방피크부하저감은 Case A 대비 Case C(2.38%) > Case B(1.82%) > case D(1.50%)로 산정되었다. 연간 냉 난방부하저감은 미적용 Case A대비 벽면녹화 유형에서 0.92~1.28% 저감률을 나타내었다. 연간 냉난방에너지사용량은 3.04~3.22%의 저감률을 보였으며, 1차에너지사용량은 Case A대비 나머지 유형에서 평균 5,844 kWh/yr의 저감량을 보였다. 연간 이산화탄소발생량은 벽면녹화 미적용 Case A대비 평균 996kg 저감량을 보였다. 식재위치별 에너지성능평가 결과 동향 > 서향 > 남향 > 북향 순이었다. 벽면녹화비율에 따른 에너지성능평가 결과 녹화 비율이 높아짐에 따라 양호한 결과를 나타내었으며, 20~80%의 비율보다 100% 녹화시 약 2배의 저감률을 보였다.

Energy loss at manholes, often exceeding friction loss of pipes under surcharged flow, is considered as one of the major causes of inundation in urban areas. Therefore, it is necessary to analyze head loss at manholes, especially in case of surcharged flow. Hydraulic experiments were conducted with three cases. Case A is to test whether the shapes of the manholes influence head loss coefficients. Case B and C were proposed to further reduce head losses by improving the manhole hydraulic efficiency. In case B, the joining part of the pipe at both shapes of manholes is shifted from central part to side part. The test in case C is to check the average head loss coefficient by installing the side benching in square manhole, based on shifted joining part model. The average head loss coefficient for circular and square manhole on case A was 1.6. This did not show much difference of the head loss coefficients in spite of the discharge variation in this case. However, case B and C show large difference between head loss coefficients due to the strong oscillation of water surface and the horizontal swirl motion. The circular and square manholes in case B reduced the head loss by 30% and 6% than ones in case A, respectively. The average head loss coefficient for circular manhole in case B was 1.1. Case C reduced average loss coefficients of the square manhole in case A from 1.6 to 1.1. Accordingly, the circular manhole in case B and the square manhole in case C showed the effective way to reduce the head loss. These head loss coefficients could be available to apply to the urban sewer system with surcharged flow.

노면에 차량 검지센서를 설치하여 개별차량의 속도자료를 수집하는 경우, 일반적으로 일정거리가 이격되게 설치한 두 개 이상의 차량 검지센서간의 반응시간을 활용하여 차량의 속도를 산출하게 된다. 본 논문에서는 차로당 센서 1개만을 설치하여 개별차량의 속도 산출을 함에 있어, 기존 방법인 파형의 기울기를 이용하여 속도 추정하는 방법(Case 1)과 평균차량길이를 적용한 속도산출(Case2), 새로 고안한 방법인 단일 테이프스위치(Tape Switch) 센서를 수평형으로 설치하고 평균축거를 적용하여 속도 추정하는 방법(Case 3), 그리고 테이프스위치 센서를 사선형으로 설치하고 차량의 평균윤거(Mean of tread)를 적용하여 속도 추정하는 방법(Case 4)에 대한 속도 추정정확도를 평가하였다. 4가지 방식 각각에 대해 현장에서 센서를 설치하고 기준값과 속도추정 값을 비교 분석을 했으며, 평가지표로는 등가계수(Equality Coefficient), 절대오차백분율(MAPE)을 통하여 평가하였다. 평가결과는 Case1 > Case 4 > Case 2, 3 순으로 양호한 결과를 보이는 것으로 분석되었다.

This paper presents a case-building algorithm which can control the design variables of which some variables are designated as the input (known) variables and the remainders are defined as the output (unknown) variables. The case-building algorithm can enhance the design ability by categorizing design case automatically. Common CAD programs for analysis and design of machine elements use a case-selection technique where a programmer set initially a few of design cases and users can only choose one of given cases. This paper also demonstrates the case-building algorithm by applying into CAD programs for power-screw design.
