This study was conducted to clarify the mediating effects of self-efficacy and organizational commitment on the level of depression associated with emotional labor and occupational stress of call center representatives. The survey subjects were 486 representatives working in four call centers in D city. Data collection was conducted using structured, self-addressed questionnaires from January 5th to 25th, 2017. The results showed that the depression level of the representatives was significantly higher in the emotional labor and occupational stress groups and higher in the low self-efficacy and organizational commitment groups. The correlations between variables revealed a positive correlation between depression, emotional labor, and occupational stress, but a negative correlation between self-efficacy and organizational commitment. Path model analysis revealed that emotional labor and occupational stress had positive effects on depression, while self-efficacy and organizational commitment was negatively influenced. In addition, self-efficacy and organizational commitment had a mediating effect on emotional labor and depression, while organizational commitment had a mediating effect on occupational stress and depression. Therefore, to reduce the depression level of call center representatives, it is necessary to reduce the emotional labor and occupational stress factors, as well as to have a mental health mediation plan to increase self-efficacy and organizational commitment.

The purpose of this study was to evaluate the characteristics of craniofacial skeleton on orthognathic surgical cases with skeletal Class III malocclusion. For this study, 74 students at the dental college of Chosun University volunteered as a normal occlusion group. They had well-balanced faces and good occlusions with acceptable Class I molar relationship. They had not received orthodontic treatment and had no signs or symptoms of temporomandibular joint dysfunction. 45 malocclusion patients enrolled for orthognathic surgical treatment with skeletal Class III malocclusion at the Department of Orthodontics, College of Dentistry, Chosun University. On the basis of this study. the results of this study were as follows: 1. Skeletal Class III malocclusion was largely due to the overgrowth of mandible in man and the undergrowth of maxilla in woman. 2. The mandible was antero-inferiorly overgrown by large MP-HP angle and large genial angle in orthognathic surgical cases with skeletal Class III malocclusion. And also, upper incisors were severely labioversioned, but on the other hand lower incisors were linguoversioned. 3. In female, lower-third facial height was characteristically shortened in comparison with middle-third facial height and also, lower facial throat angle was small in male.

In this study, we investigated the elements of knowledge and information processing competence of science inquiry activities in grades 3-6 science textbooks. For this purpose, the elements of knowledge and information processing competence were extracted and a framework for analysis was created. Analysis of eight science textbooks for grades 3-6 in elementary school was carried out using the analysis framework. The following results were obtained by the analysis framework: First, we divided the knowledge and information processing competence into five elements: 'collection,' 'analysis,' 'expression,' 'selection,' and 'evaluation.' Second, the elements of knowledge and information processing competence of science inquiry activity of elementary science textbooks were not evenly composed. The science inquiry activities of elementary science textbooks focused on 'collection' and 'analysis' among the five elements of the knowledge and information processing competence, followed by 'expression,' 'selection,' and 'evaluation.' As a result, we found that a science inquiry model or a science instruction model is needed to develop the knowledge and information processing competence in elementary school science curriculum.

We classified collaboration types of Government-supported Research Institutes (GRIs) in Korea to make a creation knowledge with the openness and the diversity. The openness is described to collaboration dependence and leading intensity, and the diversity is expressed to collaboration diversity and collaboration concentration. We suggest four taxonomy models explained in terms of the openness and the diversity with country level and institute level. This study uses 39,507 papers in SCOUPS DB that include author(s) affiliated to 26 GRIs. It concludes that many GRIs is classified to the type of multilateral collaboration follower in institute level and to the type of global network player in country level from the perspective of openness. In the aspect of diversity, many GRIs is concentrated to the collaboration type of picky eater or monophagous in institute level and to the multinatioal asymmetry type or non-multinational asymmetry type in country level. It is necessary for GRIs to lead collaboration and to transfer inhouse R&D institutes with high performance to be competitive institutes which make high quality knowledge.

This study tried to verify the causal relationship that SMEs' organizational culture and self-efficacy would affect job crafting and job satisfaction. Unlike previous domestic studies that have been studied for organizational culture at the organizational level and self-efficacy at the individual level, this study tried to verify the interaction between job crafting and job satisfaction using different mechanisms as antecedent factors. In order to verify the research model of this study, questionnaires of 144 small and medium-sized enterprises (SMEs) workers located in Seoul and metropolitan areas were analyzed. Factor analysis and correlation analysis were performed to verify the reliability and validity of the research model on the relationship between variables, and empirical analysis was performed using regression analysis and mediation effect analysis to verify the hypothesis. The results of the study were first, that organizational culture and self-efficacy had a positive (+) effect on job crafting. On the other hand, relationship-oriented culture and hierarchical-oriented culture, which are sub-factors of organizational culture, were found to be insignificant. Second, organizational culture and self-efficacy were found to have a positive (+) effect on job satisfaction. On the other hand, it was found that market-oriented culture and hierarchical-oriented culture, which are sub-factors of organizational culture, were not significant. Third, job crafting was found to have a positive (+) effect on job satisfaction. On the other hand, it was found that the sub-factors of job crafting, disruptive job demands and social job resources, were not significant. This means that organizational culture partially affects job crafting and job satisfaction of SMEs, and job crafting also partially affects job satisfaction. The implications of this study are first, suggesting the meaning of SME organizational culture for stable and efficient human resource management for SMEs suffering from low productivity and high turnover rate. Second, it was meaningful to understand the possibility of introducing job crafting as an effective job management plan for SMEs. Third, in the current situation where there are few cases of practical introduction of job crafting, research on understanding job crafting for SMEs and improving job satisfaction is thought to be helpful in improving the productivity of SMEs.

춘천 연옥은 색깔에 따라 세가지 유형 (연녹색, 암녹색, 및 회색 연옥)으로 구분되고 이들은 각기 서로 다른 조직과 조성을 나타낸다. 연녹색 연옥이 이중에서 가장 일반적인 유형이다. 연옥은 주로 극미립의 연옥질 투각섬석으로 구성되고 여기에 미량의 휘석, Mg-녹니석 및 방해석이 불순물로서 수반된다. 연옥질 투각섬석 결정들은 그 폭이 5$\mu\textrm{m}$ 이하의 극미립질 침상 결정형을 이루며 서로 치밀하게 얽혀있는 연옥 특유의 조직을 나타낸다. 주사전자현미경 하에서 (110)의 벽개면의 발달이 현저하고, 주사탐침현미경 하에서는 벽개면을 가로지르는 방향으로 특징적인 조선이 나타나는 것이 특징이다. 연옥질 투각섬석은 투과전자현미경 하에서 흔히 단쇄형과 복쇄형이 결합한 3중쇄형 격자가 복쇄형의 투각섬석 구조 내에서 불규칙적으로 협재되는 혼성격자 구조가 발달하는 것이 특징이다. 드물지만 5중쇄형 격자와 4중쇄형 격자도 관찰되는데, 이 같은 불규칙한 격자 혼재상은 회색 연옥에서 보다 현저한 경향을 보인다. 이와 같은 혼성격자 구조형의 존재는 춘천 연옥이 열역학적으로 비평형 상태에서 형성되었음을 시사하는 것으로 여겨진다. 리트벨트법에 의한 구조검증을 통해서 구해진 연옥질 투각섬석들의 격자상수 값들은 X-선회절의 경우, a=9.837(1)~9.9804(4)$\AA$, b=18.046(2)~18.062(1)$\AA$. c=5.2765(7)~5.2803(3)$\AA$, $\beta$=104.717(9)~104.786(3)$^{\circ}$로 계산되었다. 이에 비해서 중성자 회절법에 의해서 측정되 격자 상수 값은 a=9.8841(6)~9.8933(7)$\AA$, b=18.1429(7)~18.161(2)$\AA$, c=5.3024(3)~5.3060(7)$\AA$, $\beta$=104.698(7)~104.771(4)$^{\circ}$로서 X-선회절에 의한 값들과 약간의 차이를 보인다. 연옥질 투각섬석은 Ca에 대한 Mg의 치환에 의해 M(4) 자라의 크기가 작아지면서 b축의 단위포도 함께 줄어드는 결정화학적 특징을 나타낸다. 이는 중성자 회절분석에 의해서 구해진 M(4)의 자리점유율과 M(4)-O의 원자간 거리에 의해서도 확인된다. 그러나 연옥질 투각섬석에 대한 리트벨트법에 구조검증 결과는 연옥의 유형별 미시적 광물상과 혼성격자 구조형의 특징에 별다른 연계성이 없는 것으로 나타났다.

Necrotizing periodontal disease caused by plaque bacteria is showed clinical findings including pseudo-membrane, interproximal necrosis of the affected area, pain on palpation and gingiva bleeding. Microbiological examination is showed that patients have fusospirochetal bacteria. Two patients who were provisionally diagnosed as necrotizing periodontal disease received nonsurgical periodontal treatments in conjunction with dressing using 3% hydrogen peroxide and local antibiotic delivery. Before and 3 - 5 days after initial treatment, the levels of periodontal bacteria in gingival crevicular fluid obtained using quantitative PCR were compared. After treatment, patients recovered normal gingiva. The number of periodontal diseases related bacterial species decreased from seven or eight to one. As a result, periodontium of patients with necrotizing periodontal disease was recovered to normal periodontium by nonsurgical periodontal treatments.

We investigate empirically the impact of IT exploration & exploitation capability and operational capability upon organizational agility, especially small and medium sized firms in the logistics industry in South Korea. Based on literature on the bilateral relationship between organizational agility and IT capability, we follow the established research model and propose hypotheses. This work takes an empirical methodology to test the hypotheses: design survey questionnaires, collect data, test reliability and validity of data, and finally test the hypotheses. Our results based on the data collected in 2018 present that IT exploration & exploitation capability significantly increases operational capability, and operational capability increases organizational agility. We find our contribution in updating previous research findings with recent data and in expanding the domain of research more specifically into small and medium sized firms in logistics industry in South Korea. Practically our work suggests that managers and policy makers should consider both fostering newly emerging IT exploration and existing IT resource exploitation capability in order to enhance organizational agility of those small and medium sized firms in logistics industry.
