This study was carried out to evaluate the effect of the crack propagation characteristics and bond stress of ceramo-metal system. In order to characterize the crack propagation, the static crack propagation stored in $37^{\circ}C$ distilled water of two commerical porcelains and the dynamic crack propagation under cyclic flexure load of ceramo-metal system were examined. In order to characterize the bond stress, the shear bond test, the 3-point flexure bond test, and the finite element stress analysis of ceramo-metal system were conducted. The results obtained were as follows : 1. Bulk densities and Young's moduli of opaque porcelains increased with repeated firing. 2. Maximum fracture toughness during 4 firing cycles showed at the group of 4 firing cycles in Ceramco porcelain and 2 firing cycles in Vita porcelain. 3. Shear bond strength and flexure bond strength of Ceramco-Verabond specimen were larger than those of Ceramco-Degudent G specimen (p<0.05). 4. Interfacial stresses under three point flexure bond test were concentrated at the edges of ceramometal system. 5. When a cyclic flexure load was applied, the crack growth rate of porcelain surface of ceramometal specimens was decreased as load cycles increased.

전시 전투력 강화를 위한 리더-멤버 교환(LMX)관계 연구 - 임진왜란 시기 삼도수군통제사 원균과 조선수군 사례를 중심으로 -

박주미 국방정신전력원 2023 정신전력연구 Vol.- No.75

1597년 정유재란 발발 후 선조는 삼도수군통제사 이순신을 원균으로 교체하였다. 그리고 약 4개월 후 있었던 칠천량해전에서 조선수군은 궤멸하였다. 원균이라는 리더의 교체가 전시 전투력 약화와 어떠한 관계가 있었던 것일까? 이에 본 연구에서는 조직 내에서의 리더와 멤버의 교환관계에 주목한 리더-멤버교환(LMX) 이론을 통해 이 사례를 분석하고 전시 전투력 강화를 위한 LMX 관계 구축방안을 도출하였다. 본 연구에서 충성, 정서적 친밀감, 공헌, 전문성 존중의 항목을 분석해본 결과, 삼도수군통제사였던 원균은 구성원들과 낮은 수준의 관계를 유지하고 있었다. 그러나 조직 목표를 달성하기 위해서는 리더와 멤버 간의 관계의 질을 높여야 한다. 특히 원균과 조선수군의 사례처럼 전시라는 급박한 상황에서 ‘전투의 승리’라는 중대한 결과를 얻어야 할 때는 더욱 그렇다. 이를 위해서 리더는 조직지원, 권한위임, 모범행동에 의한 관리 등의 노력을 기울여야만 한다. In 1597, following the outbreak of the Japanese invasions of Korea known as the jungyujearan, King Seonjo replaced the chief officer of the navy Yi Sun-sin, with Won Gyun. And approximately four months later, during the Battle of Chilcheollyang, the Joseon Navy suffered a significant defeat. How does the leadership change to Won Gyun relate to the weakening of combat effectiveness? In this study, the leader-member exchange (LMX) theory, which focuses on the exchange relationship between leaders and members within an organization, is utilized to analyze this case and derive strategies for building LMX relationships to enhance exhibition combat effectiveness. Through the analysis of loyalty, affection, contribution, and professional respect, this study found that Won Gyun, who was the navy commander at the time, maintained a low-quality relationship with the members. However, to achieve organizational objectives, the quality of relationships between leaders and members must be improved. This is especially crucial during urgent crisis situations like period such as of war, where significant outcomes such as 'victory in battle' are at stake, similar to the case of Won Gyun and the Joseon Navy. To achieve this, leaders must focus on efforts such as organizational support, delegation of authority, and leading by example.

문화유산을 활용한 중학생 지리 답사 프로그램 개발 ― 공주 공산성을 대상으로 ―

Since Gongsanseong Fortress was designated as a World Heritage Site in 2015, the importance of Gongsanseong Fortress as a historical site in the Gongju region has been further highlighted. Accordingly, various learning and tourism programs have been developed to promote regional identity and local pride by utilizing Gongsanseong Fortress focused on history and archaeology. However, from a geographical perspective, there has been no a study on a ‘middle school geography exploration program’ that use cultural heritage to target Gongsanseong Fortress. Therefore, in this study, we developed geography exploration program to improve middle school students' geographical thinking and imagination, targeting the historical space of Gongsanseong Fortress. As a result, two exploration courses were developed in Gongsanseong Fortress. ‘exploration Course-Ⅰ’ is designed to enable middle school students to ① understanding the spatial location of exploration points within Gongsanseong Fortress, ② research topography and human geographic elements, and ③ understand the relationship between humans and the natural environment. And ‘exploration Course-Ⅱ’ is designed to help middle school students find the best estimation palace site within the fortress through the process of exploring and comparing the geographical environment of the space. This study is significant in that it is developed a geographic exploration program that can foster geographic thinking and imagination in middle school students from a geographical perspective, targeting Gongsanseong Fortress, a historical space with high academic value as a cultural heritage. Therefore, we expect that the results of this study will be meaningfully used in actual educational settings in the future

Skin-related Quality of Life in Patients with Lung Cancer Taking Oral Targeted Agents: A Single-Center, Cross-Sectional Study

박주미,김정혜 대한종양간호학회 2023 Asian Oncology Nursing Vol.23 No.2

Purpose: This study aimed to investigate the level of the relationship between skin toxicities and skin-related quality of life (QoL) in patients with lung cancer taking oral targeted agents. Methods: This cross-sectional study surveyed 152 lung cancer patients receiving oral targeted agents. The Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PROCTCAE) was used to assess skin toxicity. The Dermatology Life Quality Index (DLQI) was used to evaluate skin-related QoL. Collected data were analyzed with independent t-test, one-way ANOVA, and Pearson correlation using the SPSS 27.0 statistical analysis software for Windows. Results: Skin toxicity was the highest among patients who reported skin dryness 2.07±1.20, followed by itching 1.91±1.25, rash 1.48±1.32, skin darkening 1.39±1.16, hives 1.38±1.25, acne 1.37±1.36, nail (finger or toe) ulceration 1.34±1.34, nail ridging 1.20±1.14, sensitivity to sunlight 1.10±1.07, stretch marks 0.95±1.13, hair loss 0.91±1.14 and nail discoloration 0.83±1.07. The subjects' mean skin-related QoL of the participants was 7.29±6.11 out of 30. Skin-related QoL showed a statistically significant positive correlation with skin toxicity. Conclusion: Skin toxicities correlated significantly with poor skin-related QoL. Skin toxicity levels in lung cancer patients receiving oral targeted therapies need to be closely monitored, and strategies to enhance skin-related QoL must be developed.

『장애인 등에 대한 특수교육법』의 정책집행 과정 분석: 특수교사 법정 정원을 중심으로

박주미 복지대학교 장애인능력개발원 2016 장애인고등교육연구 Vol.2 No.2

본 연구는 2008년 특수교육계의 큰 기대 속에 시행된 『장애인 등에 대한 특수교육법』의 정책집행 과 정분석을 위해 이론적 고찰을 통한 ‘정책자체', ‘집행 기관 및 집행자', 그리고 ‘환경'을 변인으로 하는 분석 모형을 설정하였다. 정책집행 과정 속에 나타난 쟁점 가운데 가장 중요한 특수교사 법정 정원을 중심으로 정책 집행 관련 변인을 분석하였으며, 분석모형은 문헌연구를 통하여 각 변인별 하위 요인들을 설정하여 살펴보았다. 연구결과 정책집행수단 부족, 정책집행자의 집행의지 부족, 관련 부처 간 협력 부족 등이 문제 로 파악되었다. 그리고 연구결과는 외부주도형으로 채택된 정책을 원활히 집행하기 위해서는 집행 중에도 외부주도 집단의 끊임없는 목소리가 필요하며, 또한 정책집행 담당자와 주변 관련 기관들의 원활한 의사소 통 및 협조적 관계형성이 반드시 필요하다는 것을 잘 보여주고 있다.

비대칭전략의 유형과 사례분석 그리고 교훈

박주미,길병옥 미래군사학회 2020 한국군사학논총 Vol.9 No.1

An asymmetrical strategy means a war-performing method that makes the enemy unimaginable in terms of types, dimensions and forms via the analysis of my strengths and the enemy’s weaknesses. Due to the possibility of victory opened to the weak, it can be differentiated in its strategic dimension, level and type utilized in the East and West as well as in the past and present times. This inquiry analyses the Mao’s guerilla war and U-boat’s pack of wolves war as the representative case study based on the Metz and Johnson’s classification of the asymmetrical strategy. As a result, this study is reached at the following conclusion: First, an asymmetrical strategy has a powerful effect in a way that it controls the win or lose of war in the land and sea wars. Second, despite of its effects, it does not guarantee the victory by using the strategy by itself. Third, to win the battle and war, one must to apply the strategy flexibly. The asymmetrical war will be fall into the failure if he or she does not grasp and apply it flexibly according to the changes of time, opinions and situations. This study contends that South Korea needs to research and develop her own symmetrical strategy faced with North Korea and strong neighboring countries in Northeast Asia.
