As the sphere of consumers' shopping behavior expands, the need to understand shopping orientation also increases. Yet, there has been few research that investigated the nature of clothing shopping orientation[CSO]. Thus, more research that accounts for CSO is needed. The purpose of this study is to determine the concept of CSO. In order to study CSO, documentary research was conducted. The results of this study were as follows: In order to identify the concept of CSO, the concept of general shopping orientation was determined first. The results indicated that the general shopping orientation was a shopping specific lifestyle. Based on this, the concept of CSO was determined. Through investigating the relationship between clothing lifestyle and CSO, and comparing the general shopping orientation and CSO, the concept of CSO was ultimately determined as a clothing shopping specific life style, that is, a patternized clothing shopping aspect integrating consumer's activity, interest, and opinion relating to clothing shopping. It comprehends both behavioral and psychological aspects appearing while the clothing shopping, and before and after the clothing shopping. The results of this study would be useful to reduce the confusion between the concept of CSO and other similar concepts, and to guide valid research on CSO.

This study was conducted to evaluate the applicability of castor oil (CSO) as a natural wood preservative. CSO was treated into wood blocks prepared with domestic and imported wood species using a vacuum-pressure method, and then treatability, leachability and decay resistance of the CSO-treated wood blocks were examined. Although CSO was penetrated effectively into wood blocks of all wood species, the CSO-treatability was the highest in Western hemlock, followed by Japanese larch (LA), soft maple and Mongolian oak due to the difference of its anatomical structure. Except for LA, the more retained, the more leached during a saline water-immersing process for 48h. The use of ethanol added to reduce the viscosity of CSO affected negatively the treatability and leachability of wood blocks. Decay resistance, which was evaluated by the weight loss of wood blocks exposed against Fomitopsis palustris (FOP) and Trametes versicolor, of the CSO-treated/leached wood blocks was superior to that of control. Especially, most of wood blocks treated with preserving solution composed of only CSO (CSO-2) did not decayed and showed a very low weight loss against FOP. The decay resistance results from CSO retained in wood blocks after leaching. The retention of CSO could identify using the observation of X-ray microscope. Length of wood strips, which were treated with CSO-2 and then immersed in saline water for 2 weeks, hardly changed in all cutting directions. In addition, weight gain and length-swelling rate of the wood strips were extremely low compared to those of control. These results indicate that moisture resistance of the wood strips was improved by the CSO treatment. It is concluded that the treatment of CSO using a vacuum-pressure method provides the decay resistance and dimensional stability of wood, and thus CSO can be used as a natural wood preservative on various indoor and outdoor circumstances.

기업에서 정보보호의 역할이 중요해 지면서 이를 책임지는 CSO제도가 점차 도입되어가고 있다. 특히, 최근 국내 정부기관에서의 정보보호를 위한 종합대책을 발표하면서 중앙행정기관 및 지자체와 일정 규모 이상의 기업들에게 CSO 제도 도입을 의무화 하고 있다. 이런 상황에서 CSO의 역할과 변화추세, 그리과 해결해야 할 과제를 살펴보는 것은 매우 시의 적절하다고 하겠다.

While the unionization of contingent workers is at a standstill, the newly emerging peripheral workers' representation mechanism is CSO(Civil Society Organization). Unlike trade union's representation based on coercive collective bargaining and agreements CSO represents the interests of marginal workers through counseling, advocacy, public relations, and education. In the case of Korea, since the 2000s, labor CSOs, called "contingent centers", have started to spread. As a result of the survey, contingent centers which are contracted out by local governments show the possibility that the representation activities are restricted, because most of their resources are covered from the local government. This is because CSOs have limitations due to a dilemma in the process of representing funders and the represented. Nevertheless, the contingent workers' CSO in Korea shows the possibility of supplementing and supporting the role of trade unions' representation. In this regard, through the solidarity of trade unions and CSOs, it will be possible to expand the representation of unorganized and contingent workers in Korean society.

The purposes of this research were to form chitosan oligosaccharide (CSO)/A2 ${\beta}$-casein nano-delivery systems (NDSs) and to investigate the effects of production variables, such as CSO concentration levels (0.1%, 0.2%, and 0.3%, w/v) and manufacturing temperature ($5^{\circ}C$, $20^{\circ}C$, and $35^{\circ}C$), on the production and physicochemical characteristics of CSO/A2 ${\beta}$-casein NDSs to carry resveratrol. The morphological characteristics of CSO/A2 ${\beta}$-casein NDSs were assessed by the use of transmission electron microscopy (TEM) and particle size analyzer. High-performance liquid chromatography (HPLC) was applied to determine the entrapment efficiency (EE) of resveratrol. In the TEM images, globular-shaped particles with a diameter from 126 to 266 nm were examined implying that NDSs was successfully formed. As CSO concentration level was increased, the size and zeta-potential values of NDSs were significantly (p<0.05) increased. An increase in manufacturing temperature from $5^{\circ}C$ to $35^{\circ}C$ resulted in a significant (p<0.05) increase in the size and polydispersity index of NDSs. Over 85% of resveratrol was favorably entrapped in CSO/A2 ${\beta}$-casein NDSs. The entrapment efficiency (EE) of resveratrol was significantly (p<0.05) enhanced with an increase in manufacturing temperature while CSO concentration level did not significantly affect EE of resveratrol. There were no significant (p<0.05) changes observed in the size and polydispersity index of NDSs during heat treatments and storage in model milk and yogurt indicating that CSO/A2 ${\beta}$-casein NDSs exhibited excellent physical stability. In conclusion, the CSO concentration level and manufacturing temperature were the crucial determinants affecting the physicochemical characteristics of CSO/A2 ${\beta}$-casein NDSs containing resveratrol.

The purpose of this study is to develop clothing shopping orientation(CSO) scales fer more specific clothing shopping aspects. The specific aspects were the merchandise-related aspect and the store-related aspect. The two specific scales were developed based on the conceptual structure model of CSO and the general CSO scale. 16 items were selected for merchandise-related CSO, and 16 items were far store-related CSO. In addition, construct validity and convergent validity of those two specific scales were verified using AMOS 4.0, and discriminant validity were verified using Pearson's correlation. This study has significance in offering an advanced approach to the measurement of CSO.

The objectives of this study were to manufacture casein phosphopeptide (CPP)/chitosan oligosaccharide (CSO) nanocomplexes and to investigate the impacts of manufacturing variables, such as CPP concentration and pH, on their morphological and physicochemical characteristics. Transmission electron microscopy (TEM) and particle size analysis were used to assess the morphological and physicochemical properties of the CPP/CSO nano-complexes, respectively. Based on the images obtained by TEM, the spherical shapes of the CPP/CSO nanocomplexes ranged from 50 to 150 nm. As the concentration of CPP was increased and the pH was decreased, the average particle size of the nanocomplexes significantly (p<0.05) increased. The CPP/CSO nanocomplexes had a highly uniform distribution with a polydispersity index value of less than 0.3. In addition, they had a negative surface charge with a zeta-potential value between -17 and -26 mV. The CPP/CSO nanocomplexes showed good stability during the freeze-drying process. In conclusion, CPP/CSO nanocomplexes were successfully manufactured, and the CPP concentration and pH were found to be key factors that affected their morphological and physicochemical properties.

The purposes of this study are to verify the validity of the conceptual structure of clothing shopping orientation(CSO) developed in the previous research, and to explore the difference of CSO structure between male and female consumer groups. For those purposes, data of 499 male and female consumers were collected. Confirmatory factor analysis, ANOVA, and simultaneous factor analysis were used for data analysis. The results are as follows. First, as a result of confirmatory factor analysis, the validity of conceptual structure of CSO was verified. Second, as a result of ANOVA, male and female showed significantly different CSO at the lower-dimensions level, and as a result of simultaneous factor analysis, male and female showed significantly different relationships between dimensions within the structure. This means that the CSOs of both male and female can be explained by the same CSO structure model, but the specific relationships between CSO dimensions are different by the gender of consumers. Finally, directions for fashion marketing mix concerning the CSO structures of male and female were suggested.

Purpose: Citron seed oil (CSO) has been reported to have high antioxidant activity. However, the composition and other biologically activities of CSO have not been reported. In this study, we confirmed the fatty acid composition of CSO, which may be beneficial to vascular disease and obesity. Methods: We investigated the oil composition of CSO using gas chromatography coupled with mass spectrometry (GC-MS) analysis, and cytotoxicity was confirmed by Cell Counting Kit-8 (CCK-8) assay. Nitric oxide (NO) production in human umbilical vein endothelial cells (HUVECs) was measured using Griess reagent, and lipid accumulation and leptin secretion in 3T3-L1 cells were measured by Oil-Red O staining and commercial ELISA kit, respectively. Results: GC-MS analysis indicated that CSO contains several components, including linoleic acid, oleic acid, palmitic acid, stearic acid, linolenic acid, palmitoleic acid, and arachidic acid. In physiological activity analysis, CSO did not induce cytotoxic effects in HUVECs and 3T3-L1 cells. Further, CSO significantly induced nitric oxide and leptin secretion as well as inhibited lipid accumulation. Conclusion: CSO increased NO release, inhibited lipid accumulation, and induced leptin secretion, suggesting it may be useful for the management of vessels and weight gain. Although further studies are required to investigate the safety and mechanism of action of CSO, our results show that the composition and physiological activity of CSO are sufficient for its use as functional edible oil.
