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.

The purpose of this study is to establish a new rural development policy system based on the unit of a community organizations. This study is to complement or replace the existing rural development system which is based on the unit of rural villages. The communalism which is the core concept of traditional rural villages has been weakened or destroyed. Especially, economic, social and spatial communalism of a rural villages has been weakened rapidly in the process of industralization and urbanization for the last 50 years. This means that strong communalism inside rural villages and neighborhood independence from each others among rural villages are already weakened. Rural villages no longer represent rural area, unlikely the hypothesis policy makers have been used to set up rural development policies. Advanced countries like EU and Japan are well known to have a rural development policy based on the units of social organizations in the rural area. These policies have been on the main stream in the era of local decentralization. Rural resident's organization made rural site's development plan using local assets and submitted to the public sector. Then the public sector examine its value and possibilities as a rural development projects. And public sector finalize the decision on subsidy grant. These policy patterns are already introduced partly in the field of urban development programme as well as rural development programme. It is time to apply those policies more widely and to examine more systematically.

암의 진행 정도를 판단하기 위한 암세포 조직영상의 분석은 그 대상이 되는 영상의 다양성과 잡음으로 인해 정확한 분석이 어렵다. 특히, 암의 진행 정도를 판단하는데 있어서 중요한 요인인 세포핵의 variation에 따른 order/disorder 정도를 객관적 수치로 정량화하기 위해서는, 각 기(stage)에 따른 암의 진행정도를 가장 잘 나타낼 수 있는 특징값 추출이 필수적이다. 본 논문에서는 가장 유효한 특징값을 추출하기 위하여, 공간 영역과 주파수 영역에서 그 지역적 특징을 잘 나타내는 wavelet 변환을 적용한 후, 분할 된 서브 밴드 중 고대역 서브 밴드에서 질감 특징을 추출하고, 추출 된 질감 특징값들이 암의 진행 정도에 따른 각 집단간에 유의한 차이를 나타내는지에 대한 유의성을 검증하기 위하여, 다변량 통계학적 분석 방법을 사용하여 비교분석 하였다.

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.

Advances in the dental medical field now provide high quality medical service, and thus, it has become important to identify the role of dental hygienists. However, the professional status of dental hygienists has not been acknowledged, and this has resulted in problems such as dissatisfaction and high turnover rates at dental hospitals. This study was undertaken to identify factors that influence dental hygienist job satisfaction and turnover rates. To achieve this we used a synthetic approach incorporating individual (optimism), job (professionalism), and organizational (perceived organizational support) characteristics. Our results showed that optimism, professionalism, and perceived organizational support were positively related to job satisfaction. Furthermore, job satisfaction was found to be negatively related to turnover intension and to partially mediate the effect between POS and turnover intention. We believe the results of this study could be used by dental hospitals to address dental hygienist dissatisfaction and high turnover rates.

The resource-based view (RBV) explains that the competitive advantage is mainly based on the resources which have strategic characteristics. Therefore, finding, developing and maintaining strategically valuable resources has been one of main research topics and a starting point in the corporate strategy structure in RBV. In this regards, attempts to recognize strategically valuable resources have been one of crucial issues in RBV researches. Especially, Barney's VRIO has been widely used as a practical tool for finding strategically valuable resources. However, empirical studies on VRIO framework's effectiveness have not been sufficiently implemented, and there has been no proven relation among the components of the VRIO so far. This is mainly because the concepts or definitions on core components of the VRIO - Value, Rareness, Inimitability, and Organization - are too comprehensively explained and measurements of each component cannot be easily quantified. Considering these, this paper presents empirical results of the relation between VRIO components and competitive advantage, and tests effectiveness of VRIO Framework with utilizing sufficient technology evaluation cases and financial statements of 2,252 technology based SMEs in Korea. As a result, the components of the VRIO have a positive influence on competitive advantage. The attributes of strategic resources - Value, Rareness, and Inimitability - have a statistically meaningful positive effect on organization, while organization has a positive effect on the competitive advantage serving as a parameter between the attributes of strategic resources and competitive advantage.

This study was rimed out to examine the difference in the cell vitality between mesophyII protoplast (MP) and paraveinal mesophyII protoplast (PVMP) of Nicotiana tabaccum 'Xanti', Petunia hybrida 'Blue Star' and Chrysanthemum morifolium 'Baeckwang' by using urea permeability technique. The effects of various enzyme solutions and incubation time, NAA and thidiazron on plant regeneration from isolated protoplasts were also investigated. The vibratome technique was used for protoplast isolation and urea permeability test because the fresh living, thin tissue stripes (50 ${\mu}{\textrm}{m}$ of thickness) could be obtained with minimal damage with the vibratome. For the three plants examined, the urea permeability on the tested tissue stripes was relatively higher in PVMP than in MP by about Ks = 2.0 $\times$ 10$^{-5}$ cm/sec. The treatment of an enzyme mixture of 1.5% cellulase R-10, 1% Driselase, 0.5% Macerozyme R-10, and 0.5% Pectinase for 4 to 8 h was effective on the isolation of PVMP. The highest frequency of callus formation and plant regeneration from the isolated protoplasts was obtained with NAA 2 mg/L and thidiazuron 0.01 mg/L. Furthermore, the results demonstrated that cell devision and plantlet regeneration was more frequent in the PVMP than in the MP of the same leaf or plant We, therefore, conclude that UM is an excellent experimental material for the callus formation and regeneration from isolated protoplasts.

This study was carried out to compare and analyze the active ingredients of Korean native ginger and rhizome derived from in vitro shoot-tip culture of Korean native ginger. Proximate compositions, mineral nutrients, free sugars, fatty acids, volatile components, 6-gingerol, and 6-shogaol were analysed and evaluated. Korean native ginger was proved to have a little more contents than in vitro rhizome in proximate compositions (crude ash, crude lipid, crude protein, carbohydrate). Mineral nutrient contents (Cu, Fe, Mn, Zn) of in vitro rhizome were higher than those of Korean native ginger. Among the mineral nutrients, the quantity of K was the highest, followed by P, Mg, Na, and Ca. Free sugar contents (fructose, glucose, sucrose) of in vitro rhizome were higher than those of Korean native ginger. Fatty acids containing less than C14 was the major among the fatty acids in ginger. Citral ingredient of the unique aromatic compound of Korean native ginger was stronger than that of the rhizome derived from in vitro shoot-tip culture. Gingerol concentration was increased by shoot-tip culture.
