This study examines the puzzle of institutional change of irregular worker protection system in Korea through a theory of incremental institutional change. It is the case of "conversion" mode of institutional change that occurs when ambiguous rules permit reinterpretations of rules and regulations for converting functions of institutions into new ones without formal revision. Management sectors with enforcement power have circumvented main rules of high discretion since 2007. In institutional dimension, the extent of irregular workers and the provisions of limit on employment-period and prohibition-correction on discrimination lack sufficient details. In political context, veto possibilities have been downward. Irregular workers were hardly organized independently and two labor union federations mainly composed of regular workers were less receptive to them. Veto possibilities in legislation were also low: the Economic and Social Development Commission ended up in weak labor representation and labor parties in the National Assembly have undergone dissolution.

This study examines the impact of Long-Term Care Insurance(LTCI) on family caregivers(especially focused on female household members) labor supply in South Korea. When public care and informal care are substitutes, LTCI will change allocation of time of family caregivers to spend more time to paid work. The impact of LTCI on labor supply depends on each country's institutional level of public care services. If public care can not substitute for informal care, labor supply of family caregivers will not rise significantly. The conclusions of vigorous empirical study from western countries' are incompatible and problem of endogeneity in terms of methodology has been raised consistently. The dataset of this study are used the third and ninth waves of Korea Welfare Panel. As a result, the introduction of LTCI had no effect on labor supply of household members. Robust findings suggest the positive effects of caregiving on labor market outcomes in simple comparison t-test, but not in fixed-effect regression. Compared with western countries, South Korea's public care services can be interpreted as a supplement to only part that remained at the level does not substitute informal care. These findings may suggest that if LTCI become much more prevalent in the future, senior citizens and family members will be able to choose the LTCI arrangement that best suits their needs.

This is the analysis of material dyed with Korean yellow dyes such as tumeric, amur cork tree, goldthread, gardenia, and the flowers of sophora japonica using nondestructive ultraviolet-visible and fluorescence spectrophotometry. In order to find out whether type of fabric or mordant influences analysis results, test fabrics were made using two types of fabric(silk and cotton) and dyed using three different mordants(no mordant, alum, iron). After analysis with UV-Vis reflectance spectrum on the dyed fabric, when the fabric was dyed with tumeric, amur cork tree and goldthread, the results were similar with no mordant and alum mordant, whereas there was a difference with an iron mordant. Also when the fabric was dyed using gardenia, different fabrics brought different results but there was no difference in results with mordants. On the other hand, when the fabric was dyed using the flowers of sophora japonica, there was no difference with fabrics but with mordants. After analysis with 3D-fluorescence spectrum, fabrics dyed with tumeric, amur cork tree and goldthread showed their own fluorescent spectrum with no regard to fabric and mordant; but with gardenia, there were differences with different fabrics whereas with the flowers of sophora japonica, there were differences with mordants.

This paper analyzes the concept of Lacanian subject and the structural definition of sexual difference between man and woman, and criticizes some problems of those definitions. It seems to me, to do so, that it is important to know precisely the core terms of psychoanalysis quoted by Lacan. We should analyze the basic meanings and the relation of the Imaginary, Symbolic and the Real, of ideal ego and ego ideal, of phallus and signifier, of desire and the other, of consciousness and unconsciousness, of alienation and separation, etc. I'm going to discuss the relation between the Imaginary and the ideal ego in chapter 2, and then, deal with the relation between the Symbolic and the ego ideal in chapter 3. I'll explain both similarity and difference between the ideal ego and ego ideal through those discussions. In chapter 4, I'm planning to explain the relation among the other, desire and the subject of unconsciousness. In chapter 5, I'll analyze the meaning of phallus and signifier. I'll criticize the Lacanian structural definition of sexual difference on the basis of the work made in former chapters. These discussions will lead to my final conclusion that the concept of Lacanian subject and the structural definition of sexual difference are only dependent on reductionism regarding everything as symbolic, which has in itself a lot of contradiction. In order that All discussions about sexual difference have at least a objective meaning, they have to rely on anatomical differences between man and woman.

The trade volume of Northeast Asian countries is increasing and with the advent of the 4th revolutionary era, minimizing the logistics costs of firm is becoming an important competitive factor. With respect to this, in 2006, the government introduced a certified Integrated logistics firm system to improve the competitiveness of local logistics firms and reduce the logistics costs of firms. They argued that the certified Integrated logistics firm system increased the reliability of logistics firms and increased the efficiency of the logistics industry. On the other side, they argue that the system puts a burden on firms and becomes a big business-oriented market consolidation. This study analyzed the efficiency of Warehousing firms using DEA model. The CCR, BBC efficiency and RTS (return to scale) of 15 Warehousing firms were evaluated. This study also suggested the Warehousing firms which can be benchmarked based on analyzed information.

The purposes of this study were to evaluate the nasolabial angle changes between closed lip position at centric occlusion and relaxed lip position at which the bite is open so that the lips do not touch and to elucidate the significance of the relaxed lip position for dentofacial diagnosis. Methods: The subjects consisted of 60 (35 Males, 25 Females) skeletal Class III malocclusion adult patients (mean age 23.3 years) with anterior crossbite. Results: In Class III malocclusion adult patients, there were significant differences in the nasolabial angle changes between closed lip position and relaxed lip position. Using the cluster analysis, the subjects were divided into three groups according to the pattern of nasolabial angle change: Group 1 (N = 27, 45%, $-8\;{\sim}\;1$), Group 2 (N = 30, 50%, $2^{\circ}\;{\sim}\;17$), and Group 3 (N = 3, 5%, over 18). Conclusion: The results showed that the pattern of the nasolabial angle change between closed lip position and relaxed lip position varies in skeletal Class III malocclusion patients. Thus, relaxed lip position should be taken into account when diagnostic records are obtained and analyzed to accurately to evaluate the facial soft tissues and predict facial esthetics after surgical-orthodontic treatment.

$CO_2$ emissions of vehicles vary with vehicle's speeds. In addition, the speeds vary with road type, location, time and traffic volume. In this paper, the section in which a large quantity of $CO_2$ emissions per vehicle is exhausted is determined and analyzed with principal component analysis(PCA). In results of analysis, the principal components analysis were divided into two principal components. It had been identified that the main component was the time zone one which is able to explain each components' role. The first principal component could explain the role of a major component on $CO_2$ emissions per vehicle in the early morning and afternoon hour, respectively. The second principal component could explain the role of the component on $CO_2$ emissions per vehicle in the morning and afternoon peak hours, respectively. Therefore, the section in which a large quantity of $CO_2$ emissions per vehicle could be deterimined by PCA scores.

In an effort to evaluate Salmonella food safety using combinations of preservation techniques, its viabilities when exposed to HCl, acetic acid, and the oxidative agents (hydrogen peroxide and butyl hydrogen peroxide), were analyzed using sub-lethal heat-shocked Salmonella Typhimurium at $56^{\circ}C$. 2D gel electrophoresis and MALDI-TOF MS analyses were also conducted to determine the expression and repression of proteins in heat-shocked cells. Heat-shocked S. Typhimurium evidenced a reduction of viable counts by 1-2 log CFU/mL. However, viality of non heat-shocked S. Typhimurium decreased markedly by 5-6 log CFU/mL at a pH 4 in response to acid and oxidative stresses. Sub-lethal heat treatment greatly increased the resistance of S. Typhimurium against acid and oxidant agents. As for 2D gel electrophoresis and protein identification via MALDI-TOF MS, 17 major proteins in non heat-shocked S. Typhimurium were detected, and only 13 proteins among these proteins were detected in heat-shocked S. Typhimurium. The heat shock proteins such as DnaK and small heat shock proteins were included, and may be associated with the resistance of S. typhimurium against exposure to acids and oxidants. Therefore, even though the promising hurdle technology using the combined mild treatments including heat was applied to S. Typhimurium, the proper heat treatment to reduce its crossprotection activity toward the following preservative agents might be considered.

The purpose of this study was to compare and analyze changes to the middle school mathematics textbooks of third mathematics curriculum period and seventh mathematics curriculum period. This study put the math curricula from the third to the sixth one in third mathematics curriculum period as those math curricula witnessed the maintenance of industrial society paradigm. And then it put the math curricula from the seventh one to current the 2009 revised mathematics curriculum in seventh mathematics curriculum period as the knowledge-based information society paradigm has continued throughout those math curricula. Based on those period categories, We compared and analyzed changes of the middle school math textbooks. For the comparison and analysis of math textbooks between the two periods, this study set the unit organization system, unit goal, task type and content development approach as analysis elements in the unit of 'Nature of Figures' in the second grade math textbooks for middle school. As a result of the research, it was confirmed that the textbooks of the two periods had many changes in the unit organization system, but the unit goal, task type, and content development approach stayed in low level goals and task type that require conceptual and procedural.
