본 연구는 대한민국의 저출산 문제와 사회적 변화로 인한 징병제도의 지속 가능성에 대한 의문을 제기하며, 모병제 전환의 필요성과 도입 방안을 모색하는 데 목적이 있다. 대한민국은 오랫동안 징병제를 기반으로 국가 안보를유지해왔지만, 병역자원 감소와 첨단 군사 기술 발전 등의 변화에 직면해 있다. 이를 해결하기 위해 국내외 모병제사례를 분석하고, 대한민국 병역제도의 현황과 문제점을 진단하였다. 연구 결과, 모병제는 군의 전문성과 효율성을 제고하고, 개인의 선택권을 보장하며, 성별 불균형 해소와 사회적 형평성 증진에 기여할 수 있다는 장점이 있는 것으로나타났다. 또한 모병제 도입을 위해 단계적 로드맵을 제안하였으며, 이를 뒷받침하기 위한 법적 및 제도적 기반 마련의 필요성과 국민적 공감대 형성을 위한 방안을 제시하였다. 특히, 모병제 전환이 국가 경제에 미칠 긍정적 영향과장기적 관점에서의 국방비 절감 가능성도 논의되었다. 본 연구는 한국형 모병제 도입을 위한 구체적인 전략과 정책제언을 통해, 미래 안보환경 변화에 선제적으로 대응하고 지속 가능한 국방태세를 확립하는 데 기여하고자 한다.

Objective: This study aimed to evaluate the effects of force loading on root damage caused by contact with temporary anchorage devices (TADs) during orthodontic treatment and to examine the repair process 4, 8, and 12 weeks after TAD contact by micro-computed tomography (CT). Methods: We enrolled 42 volunteers who required bilateral upper first premolar extractions. The experimental study design was as follows. For both first premolars, cantilever springs were placed, and then TADs were immediately inserted between the premolars of all volunteers. According to the removal order of the appliances, the participants were divided into the TAD group (Group T: n = 21, only TAD removal) and the spring group (Group S: n = 21, only spring removal). A splitmouth design was adopted in both groups as follows. For each volunteer, the left premolars were extracted 4, 8, or 12 weeks after TAD-root contact. The right premolars were extracted immediately after contact in both groups (Groups T-C and S-C) and used as positive controls. Resorption volumes and numbers of craters were determined by micro-CT. Results: The numbers of resorption craters were higher in Group T than in Group S at 8 and 12 weeks (p < 0.01). Crater volumes were higher in Group T than in Group S at 4 and 12 weeks (p < 0.01, both). Conclusions: Root injury was not completely repaired 12 weeks after root-TAD contact, even when the TADs were removed in cases of continuous force application.

The purpose of this study is to develop a Marriage Enrichment Program that can be applied to the actual lives of Korean families and couples, as well as adopted in family welfare programs. For this study, a quasi-experimental group design was employed and pre- and post- tests on Internal-External Control, Couple Communication, and Marital Satisfaction were conducted. Experimental participants consisted of six volunteer couples who responded to an advertisement by the Chonbuk Family Counseling Center printed in a daily newspaper. The experimental group received two hours of education on marital relationship enhancement every week for eight weeks. The control group received no such treatment. The effectiveness of the education was measured by Wilcox matched pair test, using a SAS program, as well as by the self-report of the participants. The results show that there was statistically significant improvement for the experimental group in all three areas of marriage-- internal control, couple communication, and marital satisfaction. In addition, the participants'evaluations were generally positive about the program. The participants reported that it was most helpful to learn through the educational program that individuals differ in basic needs and that they should not force personal beliefs on others. They also reported that their understanding of their spouse improved.

This study investigated gait characteristics, kinematics, and kinetics in the lower extremities between two different shoe conditions (high heeled shoes (7 cm), and high heeled shoes with a total contact insert (TCI)) after lower extremity muscle fatigue. Although TCI shave been applied in high heeled shoes to increase comfort and to decrease foot pressure, no study has attempted to identify the effects of TCI in fatigue conditions. The purpose of this study was to determine the effects of walking in high heeled shoes with TCI after lower extremity muscle fatigue was induced. This study was carried out in a motion analysis laboratory at Hanseo University. A volunteer sample of 14 healthy female subjects participated. All in fatigue conditions, the subjects were divided into two groups. The muscle fatigue was induced by 40 voluntary dorsi- and plantar-flexion exercises and 40 heel-rise exercises of the dominant foot. Surface electromyography was used to confirm the localized muscle fatigue using power spectral analysis of three muscles (tibialis anterior, gastrocnemius medialis and lateralis). The results were as follows: (1) In muscle fatigue conditions, the use of TCI decreased the peak flexion angle of the hip joint significantly in the early stance phase (p<.05) and increased the peak hip flexion moment in the terminal stance phase (p<.05). (2) In muscle fatigue conditions, the application of TCI also increased peak hip power generation in the early stance phase and peak hip power absorption in the terminal stance phase (p<.05). (3) In muscle fatigue conditions, the use of TCI reduced the impact force significantly and increased the secondary peak vertical GRF. These findings suggest that the TCI may provide beneficial effects when muscle fatigue occurs for a high heeled shoe gait. Future research employing the patient population and various types of TCI materials are required to clarify the effects of TCI.
