  • Economic sanctions and inducements are types of 'policy instruments' based on 'economic tools' to influence other international actors. Ongoing debates on sanctions and inducements have exposed drawbacks for relying on individual case studies. There are some studies in the literature that attempt theoretical analysis of sanctions and inducements, but they are mostly based on rational choice theory. In reality, however, there exist so many cases that cannot be explained by rational choice theory. These are called anomalies or exceptions. The literature introduces specific variables to interpret these anomalies and thus sacrifice the universality of the theory. From this point of view, prospect theory would present an effective tool to analyze economic sanctions and inducements. It is a behavioral economic theory that tries to model a decisions making process in reality. The theory says that people make decisions based on subjective value of losses and gains from an individual reference point, and that people evaluate these losses and gains using heuristics. Thus prospect theory could offer a different frame which has greater explanatory range without adding new variables. As a result of this study, target's losses of 'back down' towards economic sanctions loom larger when the reference point level increases, therefore, the effectiveness of sanctions decreases. However, target's losses of 'stand firm' towards economic inducements loom larger under the same condition of reference point, therefore, the effectiveness of inducements increases. The findings of the paper suggest meaningful implications to the economic policy towards North Korea.

  • The trajectory preservation property that stores only one trajectory in a leaf node is the most important feature of an index structure, such as the TB-tree for retrieving object's moving paths in the spatio-temporal space. It performs well in trajectory-related queries such as navigational queries and combined queries. But, the MBR of non-leaf nodes in the TB-tree have large amounts of dead space because trajectory preservation is achieved at the sacrifice of the spatial locality of trajectories. As dead space increases, the overlap between nodes also increases, and, thus, the classical range query cost increases. We present a new split policy and entry relocation policies, which have no deterioration of the performance for trajectory-related queries, for improving the performance of range queries. To maximally reduce the dead space of a non-leaf node's MBR, the Maximal Area Reduction (MAR) policy is used as a split policy for non-leaf nodes. The entry relocation policy induces entries in non-leaf nodes to exchange each other for the purpose of reducing dead spaces in these nodes. We propose two algorithms for the entry relocation policy, and evaluate the performance studies of new algorithms comparing to the TB-tree under a varying set of spatio-temporal queries.

  • Purpose: Gluteal perforator is easily identified in the gluteal region and gluteal perforator flap is a very versatile flap in sacral sore reconstruction. We obtained satisfying results using the gluteal perforator flap, so we report this clinical experiences with a review of the literature. Methods: Between November of 2003 and April 2006, the authors used 16 gluteal perforator flaps in 16 consecutive patients for coverage of sacral pressure sores. The mean age of the patients was 47.4 years (range, 14 to 78 years), and there were 9 male and 7 female patients. All flaps in the series were supplied by musculocutaneous arteries and its venae comitantes penetrating the gluteus maximus muscle and reaching the intrafascial and suprafascial planes, and the overlying skin forming a rich vascular plexus arising from gluteal muscles. Patients were followed up for a mean period of 11.5 months. Results: All flaps survived except one that had undergone total necrosis by patient's negligence. Wound dehiscence was observed in three patients and treated by secondary closure. There was no recurrence during the follow-up period. Conclusion: Gluteal perforator flaps allow safe and reliable options for coverage of sacral pressure sores with minimal donor site morbidity, and do not sacrifice the gluteus maximus muscle and rarely lead to post-operative complications. Freedom in flap design and easy-to perform make gluteal perforator flap an excellent choice for selected patients.

  • Backgound: It has been shown that the endothelium of cardiac valves and adjacent great vessels have a reduced immune reaction compared to other vessels. We investigated the clinical feasibility of using immunologically untreated xenogenic valves, in a pig-to-goat pulmonary valve conduit implantation model. Material and Method: Porcine pulmonary valve conduits were prepared without specific immunologic treatment and implanted into the right ventricular outflow tract of goats while undergoing cardiopulmonary bypass. Two goats each were assigned to the following observation time intervals: one day, one week, three months, six months and twelve months. Echo-cardiographic examinations were performed prior to sacrifice of the goat to evaluate pulmonary valve function. After the xenograft specimens were retrieved, histological changes were evaluated microscopically. Result: Ten of the twelve animals survived the predetermined observation time intervals. Aneurysmal dilatations, of the anterior wall of the implanted pulmonary artery, were observed at each of three and twelve month-survival animals. A variable degree of pulmonary valve regurgitation was observed on echocardiography. However, valve stenosis, thrombotic occlusion and vegetation were not seen. Microscopically, the nuclei of the donor tissue disappeared as a result of pyknosis and karyolysis; however the three components of the implanted xenografts (the pulmonary artery, the valve and the infundibulum) were gradually replaced by host cells over time, while maintaining their structural integrity. Conclusion: Immunologically untreated xenogenic pulmonary valve conduits were replaced by host cells with few observed clinical problems in a pig to goat pulmonary valve implantation model. Therefore, they might be an alternative bioprosthesis option.

  • $D{\acute{o}}ck$ (Korean rice cake) is a peculiar food of Korea made of grain. By means of cooking from, it is defined as 'Pulvberzed food of grain' $D{\acute{o}}ck$ was one of the daily food, but development of boild rice had narrowed it's use to the food of festive days and ceremonies. $D{\acute{o}}ck$ is used as a main food of all Kinds of ceremonies from one's birth to death, such as the Three seven day(a baby's twenty-first day of life), one hunderdth day, birthday, wedding, both brithday, funeral and sacrifical rites, vocational ceremonies, such as a sacrifice to spirits and a srevics for a big catch of fish. It is also used as a present and seasonal food. A large variety of $D{\acute{o}}ck$ is available and its recipe is scientific and reasonable. In this treatise, the Kinds of $D{\acute{o}}ck$ and the frequency of them, the material, the recipe, the measuring unit of material, cooking kitchen utensils and the cooking terms are studied from the books published in Korea from 1670 to 1943. 1. $D{\acute{o}}ck$ was classified as Tcbin $D{\acute{o}}ck$(steamed), Chin $D{\acute{o}}ck$(strikn), Chijin $D{\acute{o}}ck$(fried) and Salmun $D{\acute{o}}ck$(boiled), according to its way of cooking. 2. There were 122 Kinds of $D{\acute{o}}ck$, 57 were Tchin $D{\acute{o}}ck$, 35 Chin $D{\acute{o}}ck$, 20 Chijin $D{\acute{o}}ck$, and 10 Salmun $D{\acute{o}}ck$. 3. There were 34 Kinds of measuring units. Of them, 13 for volume, 4 for weight, 9 for quantity, 4 for length and 4 for the rest. 4. There were 55 Kinds of cooking Kitchen utensils but now many of them are not used because of mechanization or automation of tools of living. 5. There were 143 Kinds of cooking terms. Of them 49 for the preparing process, 25 for the mixing process, 27 for well-forming process 10 for process of getting ready to cook, 14 for heating process, 10 for cutting process, 5 for dishin process and 3 for process of soaking in sugar or honey.

  • Late effects of chronic exposure to gamma radiation are potential hazards to worker in radiation facilities as well as to the general public. Recently, chronic gamma radiation exposure effects have become a serious concern. Using a total of 60 mice, we studied the biological effects of medium-dose chronic exposure to gamma radiation. Sixty female 6-week-old specific pathogen free Balb/c mice were randomly divided into six groups (five groups irradiated and one non-irradiated control group). Irradiation was carried out for 7 days using gamma rays at dose rates of 119.65, 238.10, 357.14, 476.19 and $595.24mGy\;h^{-1}$ with total doses 20, 40, 60, 80 and 100 Gy. After irradiation, we determined survival rate of gamma radiation exposed mice during 1 week and 476.19 and $595.24mGy\;h^{-1}$ exposed group mice showed less 10% of survival rate. Otherwise, 119.65, 238.10 and $357.14mGy\;h^{-1}$ exposed group mice were survived each 100%, 80% and 70%. Half of survived mice after 1 week are immediately sacrifice and counted body and spleen weights. Compared with control non-irradiated group, total body weights and spleen weights isolated from 119.65, 238.10 and 357.14 irradiated group mice showed significant decreased. However, no significant alteration was observed between 119.65, 238.10 and $357.14mGy\;h^{-1}$ irradiated group. Overall, our results show for the first time that medium-dose chronic gamma radiation has the potential to stimulation of biological effects.

  • This study is prepared to understand the filial story's communicative meaning from the aspects of Character's behavior. The filial story have typically didactic theme and it is not have enough room for another interpretations. But if we carefully analyze the filial story from the point of view of (1)the target of the filial duty[father/ mother]. (2) the actor of the filial duty[son/ daughter]. (3) the evaluator of the filial duty[witness/ recorder], we can understand the filial story's connotation. In "三國遺事"(Memorabilia of the Three Kingdoms) and "三國史記"(Historical Records of the Three Kingdoms), the target of the filial duty plays an important part and communicates with the actor of the filial duty but there's no more communication in "高麗史"(History of Corea). As the character's communication is lessened, the meaning of edification is emphasized.

  • This study investigates the social discourse for Korean women's leisure culture and analyzes the conflicts between the ideologies which affected to the women's leisure issues with the social and cultural context. For this purpose, this study analyzed a sum of 652,513 words of 4,614 news articles about Korean women's leisure by applying semantic network analysis. In the 1960s, both the enthusiasm for 'modernization' and 'good wife and wise mother' ideologies were simultaneously affected to women's leisure discourse. 'The good wife and wise mother' ideology have a stronger impact on women's leisure culture in the 1970s. In the 1980s, even though the Korean women had higher education background and advanced social status compared to the former periods, both 'good wife and wise mother' ideology and 'modern career women' ideology conflicted each other. The conflicts between the two ideologies were intensified in the 1990s and the women tended to sacrifice their leisure in the course of the ideological conflicts in the 2000s. In the 2010s, women who exhausted due to the intensified conflicts between the two ideologies showed preference for passive forms of leisure.

  • This is an attempt to analyze original films of ChunHyang Jun that Shin Sang-Ok filmed in North and South Korea, focusing on the character of MongYong. These films were made during political transition periods of North and South Korea. Sung ChunHyang was made during the second republic of South Korea, which was established after the collapse of Rhee SyngMan government; and Love, Love, My Love was made in North Korea during the period of power transfer from Kim Il-Sung to Kim Jong-Un. Considering these political changes, the character of MongYong seems to represent the figure of authority North and South Korean society of the time had in mind. First, MongYong in Sung ChunHyang has a strong image of a lover who repays ChunHyang's devotion and sacrifice with romantic affection. As an authoritative figure, he has the aspect of a democratic leader or mediator. On the other hand, MongYong's image in Love, Love, My Love is a heroic authority figure of the revolutionary class. He is a subversive reformer who shows love for the people and treats them favorably, gaining public desire. This research is expected to inspire more studies on the meanings of hit movies based on classic literature under synchronic terms.

  • This study is a meta-analysis based on results of empirical studies related to work-life balance(WLB), and the relationships between WLB and other variables. In order to achieve this objective, articles published in domestic journals prior to December 2018 were collected. Data was collected using an online database provided by the Korea Educational and Scientific Information Service, and a total of 27 studies and 126 sub data were coded. Data was analyzed using CMA (comprehensive meta-analysis) 3.0 program. Results of this study are as follows. First, the overall mean effect size of WLB was 0.365, indicating a small effect size. Second, the effect sizes of dependent variables influenced by WLB included immersion, innovation, and performance in order. Third, the effect size of organizational focus variables was more than twice as big as that of individual focus variables. Fourth, the negative theoretical background dependent variables of WLB, such as sacrifice, job stress, and turnover showed -0.254 effect size, and the positive theoretical background dependent variables, such as job satisfaction and emotional commitment have mid-size effect (0.576). Fifth, the effect size of independent variables were in the order of work-development balance, work-home balance, and work-leisure balance.
