While trust and commitment, essential ingredients of the relationship quality variables, are core mediating variables for the purpose of maintaining the long-term relationship, in the context of the internal political economy of company and the relational performance of its members, there have been limited studies which explore as to how each of the dimensions have affect differently. The basic purpose of this study is to examine the relationship between an automobile manufacturer and its agencies. The main purpose of this study is to examine how each different dimension of trust and commitment on the automobile manufacturer have different mediating effects in the context of internal political economy variables and relational performance perceived by its agents. Another purpose is to investigate the mechanism by which the relational performance of the agencies is improved. An empirical study surveying 115 sales office managers at a leading automobile manufacturer in Korea was conducted. An analysis of the collected data indicates that while internal political economy variables have a positive influence on the agencies' relational performance through the mediating role of trust and commitment, agencies' benevolence on its headquarter has a different influence on the dimensions of commitment. Currently, an automobile manufacturer is advised to implement the relational management philosophy in dealing with its agencies with an hope of innovative orientation for customers. In this sense, this study is a big stride in providing ample implications for the automobile manufacturer in establishing trust and commitment, which are the prerequisite conditions in developing and maintaining a successful long-term relationship with its agencies, and in improving the agency's relational performance.

Many organizations divide the network to manage the network in order to prevent the leakage of internal data between separate organizations / departments by sending and receiving unnecessary traffic. The most fundamental network separation method is based on physically separate equipment. However, there is a case where a network is divided and operated logically by utilizing a virtual LAN (VLAN) network access control function that can be constructed at a lower cost. In this study, we first examined the possibility of bypassing the logical network separation through VLAN ID scanning and double encapsulation VLAN hopping attack. Then, we showed and implemented a data leak scenario by utilizing the acquired VLAN ID. Furthermore, we proposed a simple and effective technique to detect and prevent the double encapsulation VLAN hopping attack, which is also implemented for validation. We hope that this study improves security of organizations that use the VLAN-based logical network separation by preventing internal data leakage or external cyber attack exploiting double encapsulation VLAN vulnerability.

Objectives : Computer-based test (CBT) will be introduced in the national examination of Korean medicine doctors from 2023. This study was aimed to provide some information, including prior considerations, to those preparing for CBT, by presenting a summary of the survey results from participants in a CBT simulation test. Methods : In December 2020, applicants from the graduating class of the college of Korean medicine from four universities participated in the simulation test for CBT. An online anonymous survey on the applicants' preference for CBT versus paper-based tests (PBT) was conducted. The questionnaire consisted of multiple-choice questions on a 5-point Likert scale and free-form questions. Results : A total of 176 students responded to the survey. Their response to CBT was generally positive. The item with the highest agreement was that it should provide a sufficient opportunity to experience CBT in the undergraduate exam (4.38±0.839). Concerns about the possibility of cheating or poor concentration were also detected. In addition to guaranteeing the stability of the CBT system, there were many comments expressing the need to supplement functions within the CBT system, including the memo or highlighter function. Conclusions : This study confirmed the feasibility of CBT including multimedia questions in the field of Korean medicine education and identified overall positive responses from those who experienced the CBT simulation test. Although time is short and there is so much to prepare, we hope this will be a leap forward for effective educational innovation in line with the changing environment of the health care education field.

Objective: There are currently no disease-modifying medications or definite long-term sustainable interventions for patients with Parkinson's disease (PD), indicating an unmet treatment need. Our goal was to create a long-term sustainable intervention for PD patients that can be used in Korean medicine clinics. Methods: The Meridian Activation Remedy System (MARS) was created to stimulate a patient's 12 meridians and sinew channels using a combination of acupoint stimulation and exercise. The acupoints and motions used in MARS were selected through literature studies and expert advice. The methodologies were refined using observational and case studies. With slow and fast movements, the MARS intervention was intended to activate both slow- and fast-twitch muscle fibers. Intradermal acupuncture and motion that shift the center of gravity were employed to enhance the patient's balance and proprioception. In addition, the intervention included alternating movement exercises to address the complex cognitive decline commonly occurring in PD patients. Results: The following acupoints were chosen for the MARS intervention: bilateral Hegu (LI4), Houxi (SI3), Waiguan (TE5), Neiguan (PC6), Zhongchong (PC9), Yuji (LU10), Zusanli (ST36), Yanglingquan (GB34), Taichong (LR3), Kunlun (BL60), and Taixi (KI3). We also developed actions that can stimulate the body's 12 meridians. Conclusion: We developed the MARS intervention, which combines acupuncture and exercise, to address the unmet therapeutic needs of PD patients. We hope that with additional research, the MARS intervention can be set as an effective therapeutic program for PD patients.

Digital transformation is taking place rapidly around the world. As the development of digital technology becomes very fast, more information is expected to be digitized. Therefore, the possibility of cyber threats is increasing in transmitting and storing sensitive information such as personal and financial information online. In this paper, we compared and analyzed information security textbooks for elementary and secondary school students in China, where the recent development of artificial intelligence and digital transformation are rapidly occurring. After we collected related textbooks, textbooks suitable for analysis were selected. Then, we analyzed the external and internal systems of the textbooks separately. As a result of the external system analysis, all the textbook covers were properly produced, but the quality difference was significant among textbooks. In the case of textbooks for elementary school students, the excellence of layout and content placement was noticed. On the other hand, due to the internal system analysis, various contents were not included evenly when looking at the learning contents based on the "information society responsibility" learning goals presented in China. Through this paper, we hope to provide implications for information security-related education and textbook development research.

As North Korea passed from the Devotion (Jeongseong) movement to the black market (Jangmadang) system, the medical service system in that country was effectively destroyed. North Korean physicians who have successfully defected to South Korea (North Korean defector physicians, NKDPs) have experienced socio-economic hardships on their way to becoming incorporated into the South Korean medical system due to different medico- social cultures, different (English-based) medical terminology, and the clinical knowledge gap between North and South Korea. Since 2009, we have operated programs at the Seoul Medical Center to help NKDPs prepare for the South Korean medical licensing examination. These programs consist of clinical education at the medical center, personal mentoring, arrangement of educational programs at the medical college, mock tests at the consortium, and administrative aid. Looking forward, we hope to achieve the following: 1) More systematic support plans are needed involving medical education experts, field physicians, and experts on reunification. 2) An evaluation of defector physicians' current medical knowledge may provide information about the areas where supplementary education is most needed and the standards for certificating licenses. 3) In the short term, a customized glossary should be developed to assist defector physicians prepare for the examination. 4) To secure internships and residencies is the most important issue for further sustained training of NKDP physicians to become good clinicians after certification. Hopefully, this short report on the current ongoing educational course will lead to more extensive discussion.

Purpose: The purpose of this study was to develop a MOL instrument for school-age children in grades 4 through 6. Method: The research design was a methodological study. A four-phase design involved. 1) Interview data generated from professors, nurses, and elementary school students (n=8). 2) Content validation by expert panel (n=14) 3) Initial items corrected by elementary school students (n=20) 4) Instrument validation by survey (n=574). Finally, 24 items were chosen as a meaning of life scale for late school-age children. Results: The Cronbach's alpha coefficient of 24 items was .893 indicated a high internal consistency of the instrument, 2) Through factor analysis, 5 factors were extracted. These factors were labeled as 'relational experience', 'positive attitude', 'satisfaction/ hope', 'pursuit of goal', and experience of family love. These factors explained 52.311% of the total variance. Conclusion: The MOL scale for late school-age children can be used in nursing programs to improve the meaning of life. Studies on difference in meaning of life for late school-age children are needed for reverification.

Escherichia coli responds to ever-changing external and internal stresses by rapidly adjusting its physiology for better survival. This adjustment occurs at all levels including metabolites as well as mRNAs and proteins. Although there has been many reports describing E. coli's adaptation to various stresses regarding transcriptomics or proteomics, only a few investigations have been reported regarding this adaptation viewed from metabolites' perspective. We applied four different types of stresses at four different doses as imposed by NaCl, sorbitol, ethanol, and pH to investigate the similarities or differences among the stresses, and which stress causes the largest perturbation of the metabolite composition. We profiled the metabolites under such external stresses by using two-dimensional NMR spectroscopy and identified 39 metabolites including amino acids, sugars, organic acids, and nucleic acids. According to our statistical analysis, the osmotic stress caused by sorbitol differentiated itself from others, while NaCl showed the largest dose dependent metabolic perturbations. We hope this work will form a foundation on which an approach to a successful protein production is systematically provided by a favorable metabolic environment by imposing proper external stresses.

With the rise in national GNP, there has been a surge in people requiring adequate housing. The most who are in need of adequate housing are fresh graduates who have entered the job market, and newly-wed couples. Given the current economic condition it is difficult for young people and newly-wed couples to find reasonably affordable accommodations. In response to this, the government is trying to formulate a new policy, with the aim of helping young married couples find decent accommodation in response to the housing shortage. Research was performed last July with the aim of looking at the differences between the newlyweds' expectation of the idealistic housing and conditions. Questionnaires were distributed to undergraduate and postgraduate research students to find out their requirements. The questionnaire investigated the social background and the condition of the inhabited area; housing type internal facilities; the space required for housing; interior finishing, and storage facilities. The survey results were analyzed using SPSS and found that the design of small residential areas, the space requirements of more diversified individualized areas were the most important concerns for undergraduate and postgraduate research students. From the study we hope this will form a foundation for the design of the future housing social stratum. It is hoped that the current results and conclusions of this survey will be of help for the korean community to provide a direction and a positive input in the future design of newly married housing.
