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.

This study is aimed to analyze the reduction performance of building energy consumption according to planting base types of panel-type green walls which can be applied to existing buildings. The performance was compared to the general performance of green walls that have demonstrated effects of improving the thermal environment and reducing building energy consumption in urban areas. The number of planting base types was 4 in total, and simulations were conducted to analyze the thermal conductivity, thermal transmittance, and overall building energy consumption rate of each planting base type. The highest thermal conductivity by the planting base type was Case C (0.053W/mK), followed by Case B (0.1W/mK) and Case D (0.17W/mK). According to the results of energy simulation, the most significant reduction of cooling peak load per unit area was Case C (1.19%), followed by Case B (1.14%) and Case D (1.01%) when compared to Case A to which green wall was not applied; and the most significant reduction of heating peak load per unit area was estimated to be Case C (2.38%), followed by Case B (1.82%) and case D (1.50%) when compared to Case A. The amount of yearly cooling and heating energy use per unit area showed 3.04~3.22% of reduction rate. The amount of the 1st energy use showed 5,844 kWh/yr of decrease on average for other types when compared to Case A. The amount of yearly $CO_2$ emission showed 996kg of decrease on average when compared to Case A to which the green wall was not applied. According to the results of energy performance evaluation by planting location, the most efficient energy performance was eastward followed by westward, southward and northward. According to the results of energy performance evaluation by planting location by green wall ratio, it was found that as the ratio of green wall increased, the energy performance displayed better results, showing approx. double reduction rate in energy consumption at 100% of green wall ratio than the reduction rate at 20% to 80% of green wall ratio.

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.

To detect individual vehicular speed, double loop detection technique has been widely used. This paper investigates four methodologies to measure individual speed using only a single loop sensor in a traveling lane. Two methods developed earlier include estimating the speed by means of (Case 1) the slop of inductance wave form generated by the sensor and (Case 2) the average vehicle lengths. Two other methods are newly developed through this study, which are estimations by measuring (Case 3) the mean of wheelbases using the sensor installed traversal to the traveling lane and (Case 4) the mean of wheel tracks by the sensor installed diagonally to the traveling lane. These four methodologies were field-tested and their accuracy of speed output was compared statistically. This study used Equality Coefficient and Mean Absolute Percentage Error for the assessment. It was found that the method (Case 1) was best accurate, followed by method (Case 4), (Case 2), and (Case 3).

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.
