This study was descriptive research examining the effects of gender role conflict and major satisfaction on college life adaptation of male nursing students. The subjects of this study were male nursing students enrolled in three universities located in D metropolitan city from March 2 to April 30, 2020. The SPSS 22.0 program was used for data analysis, frequency and percentage, mean and standard deviation, correlation analysis, t-test, and ANOVA. As a result, the average of the gender role conflict among male nursing college students was 3.70±0.43 points. The major satisfaction level was 2.84±0.24 points, and the college life adaptation was 2.49±0.28. The characteristics of the variables according to general characteristics showed that gender role conflict was significantly related to age; major satisfaction was significantly related to age and type of residence, and college life adaptation was significant according to age and military service. Based on the above results, it is necessary to establish positive professional intuition as a way to increase the adaptation of male nursing students to college life and to develop programs actively to reduce gender role conflict and increase the major satisfaction by promoting awareness related to sexual identity.

The purpose of this study is to investigate the impact of members' perception of unit change management efforts on their emotional-organizational commitment during the military restructuring. The mediating effect of change acceptance of the members in this relationship is also studied. Currently, the military is seeking to restructure its military construct in order to actively cope with the rapidly changing security situation and the decrease in military service resources. If an organization fails to effectively manage its changes when undergoing restructuring, it is difficult to expect the success of organizational change due to its members' resistance to change. Therefore, this study suggested the effect of members' perception of personnel fairness and transformational leadership on their emotional-organizational commitment and the mediating role of the members' change acceptance in the relationship between them as the hypotheses. Survey results show that personnel justice and transformational leadership has a positive impact on the emotional-organizational commitment of the members, and that the change acceptance of the members partially mediates the relationship between them. By presenting the mediating effect of change acceptance with theoretical implications, the theory has been expanded. In practice, the change management activities for the restructuring of the military structure have been identified, and the effort for enhancing the change acceptance of the members is required to success on the organizational restructuring.

Due to COVID-19, non-face-to-face cultures such as remote classes, remote work, and tele-medicine are spreading. The major contributors to the settlement of such a non-face-to-face society are small and medium SW companies and SW manpower. However, recently as large platform companies and foreign big tech companies hire thousands of SW manpower, SW small and medium-sized companies are experiencing a serious manpower shortage. Therefore, the purpose of this study is to suggest policy alternatives for SMEs to stably secure SW manpower and support continuous business operation. To achieve this purpose, this study examines the current status of the SW industry and manpower, then summarizes related issues and suggests policy alternatives to solve these issues. Those policies include the reinforcement of incentives to support manpower retention such as the Naeil Chaeum deduction system, youth housing union composition, special military service system, recruitment of manpower through the contract semester system of employment conditions, reinforcement of customized education through supplementation of the SW manpower training voucher system, SW field skill standardization, establishment of a governance system for nurturing SW manpower, preparation of countermeasures against the outflow of manpower to large companies, and a win-win cooperation program for large and SME SW manpower.

Initially entering into the job market during hard times with unfavorable market institutions has a persistent, negative effect on young workers' subsequent employment. This paper analyzes hysteresis in youth unemployment by using a composite fixed-effect panel data model. Data sets for the age-cohort unemployment rate and for labor market institutions are constructed from OECD statistics from 21 advanced economies, including Korea, from 1985 to 2017, and are then readjusted to match with the peculiarities of the Korean market. In Korea, with a less-aggressive stance on active labor market policy spending, a male worker who experiences a one percentage point higher youth unemployment rate when he was 20- to 29-years-old has a 0.146 percentage point higher unemployment rate at the ages of 30-to 34-years-old and a 0.035 percentage point higher unemployment rate at the age of 35- to 39-years-old. These figures are larger than those in most countries that have more aggressive spending schemes. These findings point out that hysteresis in the Korean labor market can be mitigated by expanding active labor market policy spending more aggressively and more effectively.

This study was conducted to test the effects of participation in 12-week program of boxing aerobics by obese middle-aged women on their body composition, blood constituents, and vascular compliance The samples are the middle-aged women in their forties or more, who has 30% or more body fat percentage, but has no medical history in cardiovascular disorders or metabolic diseases. The samples are divided into 8 of exercising group, and 8 of control group by random assignment. The intensity of boxing aerobics was HRmax 50% for the initial 4 weeks, HRmax 60% for the 5th to 8th week, and HRmax 70% for the 9th to 12th week. Each session took 60 minutes. The result is as follows. First, as a result of participating in the boxing aerobics program, body weight, body fat percentage, and muscle showed significant differences depending on the measuring period and the interacting term of the group and measuring period(p<.001), and the result of t-test on the sample matched to each group's measuring time also showed the significant increase or decrease in the exercising group(p<.001). Second, as a result of participating in the boxing aerobics program, the exercising group's TC, TG, HDL-C, and LDL-C, all showed significant differences in accordance with each group, measuring time, and the interaction term between groups and measuring time(p<.01, p<.001), and the result of t-test on each group's samples matched to the measuring time also shows significant increase or decrease in the exercising group(p<.01). Third, as a result of participating in the boxing aerobics programs, the vascular compliance of right hand, left hand, right hand, and left hand showed significant differences in accordance with each group, measuring time, and the interacting term between the measuring time and the group(p<.001), the t-test results of the samples matched to the each group's measuring time also showed significant differences in the exercising group(p<.001). To summarize the results above, it is suggested that the 12-week boxing aerobics program can improve body composition, blood constituents, and the blood circulation, which may prevent or enhance relevant diseases such as cardiovascular disorders.

Ongoing and extensive urbanisation, which is frequently accompanied with careless construction works, may threaten important archaeological structures that are still buried in the urban areas. Ground Penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT) methods are most promising alternatives for resolving buried archaeological structures in urban territories. In this work, three case studies are presented, each of which involves an integrated geophysical survey employing the surface three-dimensional (3D) ERT and GPR techniques, in order to archaeologically characterise the investigated areas. The test field sites are located at the historical centres of two of the most populated cities of the island of Crete, in Greece. The ERT and GPR data were collected along a dense network of parallel profiles. The subsurface resistivity structure was reconstructed by processing the apparent resistivity data with a 3D inversion algorithm. The GPR sections were processed with a systematic way, applying specific filters to the data in order to enhance their information content. Finally, horizontal depth slices representing the 3D variation of the physical properties were created. The GPR and ERT images significantly contributed in reconstructing the complex subsurface properties in these urban areas. Strong GPR reflections and highresistivity anomalies were correlated with possible archaeological structures. Subsequent excavations in specific places at both sites verified the geophysical results. The specific case studies demonstrated the applicability of ERT and GPR techniques during the design and construction stages of urban infrastructure works, indicating areas of archaeological significance and guiding archaeological excavations before construction work.

The clinical efficacy of Ethaverine, a peripheral vasodilator, was studied according to a double-blind, non-cross over method in 29 diabetic patients with peripheral arterial diseases. The clinical improvement was assessed from the history of patients including the incidence and frequency of intermitten claudication. Ethaverine, after 4 weeks of therapy, was not effective in improving clinical symptoms compared to placebo. Ethaverine, however, was an efective vasodilator than placebo. The quality of vasodilation induced by Ethaverine, was similar to that of alcohol. A new clinical method of studying peripheral vasodilator was presented. The clinical symptoms of peripheral vascular arterial disease in the lower extrimities include reduced intensity of palpable pulses, coldness, and discoloration of the skin. Intermittent claudication may be present. Pathologic changes in vessel architecture precede the symptoms, and recognition of impending vascular insufficiency is a determining factor in selecting vasodilating therapy or surgical management. Also, post-operative patients who have chronic peripheral vascular arterial disease may be candidates for subsequent vasodilating therapy. Peripheral vasodilators, according to the series of reports, may be indicated in vasospastic peripheral vascular condition rather than an occlusive vascular disease and the vessel responds best when a relatively large vascular beds are involved rather than a small, capillary beds. Recently, the clinical efficacy of peripheral vasodilators have been challanged by many clinical investigators and clinicians. In this study, we have re-evaluated the efficacy of Ethaverine HCl as peripheral vasodilator in patients with vasospastic peripheral arterial disease. Ethaverine is claimed to be two to four times as potent a spasmolytic agent as papaverine in a variety of laboratory and clinical work.
