The purpose of this study was to examine the difference in depression level of Japanese, Chinese and Vietnamese wives who are residing in Korean society. Special focus was taken to compare the differences in terms of the origin of nationality. Guided by the role theory, we analyzed the effect of parental role and work role on depression of foreign wives. Also we considered the social resources, ethnic characteristic that are well-known to be associated with the role performance, in this study. The data came from the sample of 524 foreign wives case (Japanese 35%, Chinese 31%, Vietnamese 34%). The result show us that depression level is different by origin of nationality of foreign wives: Vietnamese wives were more depressed compare to Japanese or Chinese wives. The effects of two social role on depression were significant even if the social resources and ethnicity are considered in the model. However, the strength of the effect of social roles were different by one another: having a job was especially effective to decrease the Chinese wife's depression level, while for the Vietnamese wives, parental role was essential to lower the depression level. In addition, the social determinants of depression were differ by the nationalities of wives. The results imply that the social adaptation process of foreign wife may be varied by the origin of nationality.

To investigate genetic features and the allele distribution of transferrin gene in three Cheju horse groups (group I, 137 horses of Jeju institute; group II, 107 horses of farms; group III, 89 racing horses) and three foreign breeds(l03 Thoroughbred, 10 Mongolian and 5 American Quarter horses), transferrin gene exons 13, 15, and 16 were analyzed by SSCP. The allele frequencies of transferrin gene of these groups and breeds were used to calculate genetic distances and to test population differentiations. The Fst values were 0.067 between Cheju horse groups I and II, 0.070 between Cheju horse groups I and group III, 0.091 between Cheju horse group I and Mongolian breed, and 0.189 between Cheju horse group I and Thoroughbred breed. Cheju horse group I showed significant population differentiation from other two Cheju horse groups and three foreign breeds while Cheju horse group III showed significant population differentiation only from Cheju horse group I and Thoroughbred breed(p <0.05). Results indicate that three Cheju horse groups showed population differentiation between each other, suggesting genetic heterogeneity of Cheju horses.

We investigated the phylogenetic diversity of ammoniaoxidizing bacteria (AOB) in Yellow Sea continental shelf sediment by the cloning and sequencing of PCR-amplified amoA and 16S rRNA genes. Phylogenetic analysis of the amoA-related clones revealed that the diversity of AOB was extremely low at the study site. The majority (92.7%) of amoA clones obtained belonged to a single cluster, environmental amoA cluster-3, the taxonomic position of which was previously unknown. Phylogenetic analysis on AOB-specific 16S rRNA gene sequences also demonstrated a very low diversity. All of the cloned 16S rRNA gene sequences comprised a single phylotype that belonged to the members of uncultured Nitrosospira cluster-1, suggesting that AOB belonging to the uncultured Nitrosospira cluster-1 could carry amoA sequences of environmental amoA cluster-3.

In this paper, A localized electromotion scooter controller for the senior and disabled is developed. Recently, the population which uses the electromotion wheel chair or electromotion scooter is increasing. The reason is that the electromotion wheel chair and electromotion scooter were newly applied in medical treatment grant item. In the whole world, electromotion scooter controller is coming to be produced above a hundred of millions. The products produced are consuming from most Europe and North America. the demand is increasing rapidly in Korea. The electromotion scooter which is sold to domestic is about 40,000 units, and about 70% or more in the products are imported from the foreign nation. Also controller for electromotion scooter uses the foreign nation product. Consequently, as the localized electromotion scooter controller is developed, it will be able to expect an income substitution effect, and apply to the agriculture and leisure mobile equipment parts.

Today, with the development of modern civilization, the change of industrial structure and the increase of traffic volume and population make the number of maxillofacial injury patients also increase. Especially, the fracture possibilities of mandibular condyle have been increased because of mandibular position and shape. I experienced the case that mandibular condyle fracture caused by gun-shot injury(Bullet had been packed at the opposite condyle of input site) was treated by foreign body removal and condyle open reduction. I will represent that case with the journal review.

Craniocerebral gunshot injuries is gradually increasing in the civilian population with a worse prognosis than closed head trauma. We experienced a case of craniocerebral gunshot injury which a bullet penetrating from the submandibular area into the clivus of a patient. The patient did not show any symptom. However, serial laboratory findings showed an increase in blood lead level. We removed foreign bodies without any problems using an endoscopic transnasal transclival approach. Due to the extremely low frequency, guidelines for definitive management of gunshot injuries have not been presented in Korea yet. We introduce our surgical experience of a craniocerebral gunshot injury with an unusual approach for removing intracranial foreign bodies.

Use of appropriate technique for non-response occurring in sample survey improves the accuracy of the estimation. Many studies have been conducted for handling non-ignorable non-response and commonly the response probability is estimated using the propensity score method. Recently, post-stratification method to obtain the response probability proposed by Chung and Shin (2017) reduces the effect of bias and gives a good performance in terms of the MSE. In this study, we propose a new response probability estimation method by combining the propensity score adjustment method using the logistic regression model with post-stratification method used in Chung and Shin (2017). The superiority of the proposed method is confirmed through simulation.

Memory T cells that mediate fast and effective protection against reinfections are usually generated upon recognition on foreign Ags. However, a "memory-like" T-cell population, termed virtual memory T (T_VM) cells that acquire a memory phenotype in the absence of foreign Ag, has been reported. Although, like innate cells, T_VM cells reportedly play a role in first-line defense to bacterial or viral infections, their protective or pathological roles in immune-related diseases are largely unknown. In this review, we discuss the current understanding of T_VM cells, focusing on their distinct characteristics, immunological properties, and roles in various immune-related diseases, such as infections and cancers.

In response to the recent decline in the school-age population, universities have made attracting foreign students a major policy task for universities. As a result, the number of foreign students increased rapidly in terms of quantity, but in terms of quality, the risk is inevitable. Accordingly, the government presented education and internationalization competency certification system indicators on the basis of which quality control of students was systematized. Based on the above certification system, this study focused on analyzing the multiple factors that are actually given to the academic adaptation (performance) of the 2200 students who entered a certain university. In addition, factors other than the certification system index were discovered to comprehensively track how they affect the academic performance of students studying abroad. The researcher found the multi-reciprocal model analysis showed that the difference between the learner and the moderator was significant, and whether or not they had the Korean proficiency test (TOPIK) was significant. It also said that it could have a direct impact on Chinese University Entrance Exams (高考) are significant. If a model that is very effective in selecting students is established by each university and used as an indicator through this study, it will serve as a basis for efficient selection of students.

The main goal of this research was to understand housing environment as well as the living behaviors of Korean people who reside in foreign countries. This study includes examination of dwelling units, especially focusing on dwelling behaviors by space types, arrangement and use of the space, and the according residence patterns of the Koreans in the United States. Focus group interview method and survey method were conducted; photography were taken as a visual evidence; and results were analyzed by researchers. This study strongly indicates that most of Koreans try to keep their own way of living in foreign cultures and rather readjust the housing spaces and living patterns to their own culture. The results from this study have limitations in generalizing all Korean families living in foreign cultures, because a convenience sample was used. Although studies of Korean families in Columbia, MO may not provide information that can be generalized to the entire population of Koreans overseas, we expect that this study provides useful insight in understanding and estimating the future trends in residential planning for Koreans.
