This study was an attempt to understand difficulties of health behaviors of the Migrant inter-marriage women and to describe the meaning of their experiences. The research data of difficulties of health behaviors of the Migrant inter-marriage women were collected in 2010 from April to May by using in-depth interviewing and observation method. Data from interviews and participant observations were analyzed according to Colaizzi's method. The findings shows that the central phenomenon for difficulties of health behaviors of the Migrant inter-marriage women are lack of health information, suffer through cultural differences, uncomfortable for using the health care centers and ends in the feeling of loneliness.

The aim of this paper is to examine the demographic characteristics and the attitude about marriage and the policy of the unmarried male farmers. The contents of research are two folds: 1) Analyze the marriage related demographic statistics of rural area using the data from Korea Statistical Information System and marriage statistics in 2007, 2) survey analyses of the attitude toward marriage, perception and needs of international marriage, and related policies from data of 170 unmarried male farmers. The results are as follows: first, the marriage rates among over 15 years old of the rural area is 78.2% for men while 1.8% for 20${\sim}$24 age group and 9.3% for 25${\sim}$29 age group. The marriage rates in this area are varied by region especially low in Kyunggido & Jejudo. Second, the portion of international marriages of Korean male farmers with foreign partner are 11% among all international marriages of Korean males. There are high rates of male farmers' international marriage in Junranamdo and Kyungsangbukdo which are characterized by low level of urbanization, low inter-city mobility, low rates of age group of under 15 years and high portion of over age 65. Finally, the survey results showed that 83% of the sample lived with their parents; event though 80% of farmers think marriage is necessary, 60% had no plan of marriage because of difficulties to meet marriage partners and of lacking economic resources; they showed a negative perception toward the handicapped, foreigners, Afro-Americans, Westerners and divorcees as a marriage partner; they also showed negative recognition to international marriage because of observed problems of neighboring international marriage couples and concerns of cultural differences; they pointed out that the government's concern about improving quality of the environment of the rural area and reforming the international marriage aid law was the most necessary. The discussion and the future research directions were added.

Unequal distribution of shares among children during intergenerational transference of assets has been prevalent in Korea. This study intends to examine whether parental contribution, in the form of a cash gift, is differentiated between the bride's side and the bridegroom's side at marriage and by age group. This pattern may also change according to the generation. Questionnaires were equally distributed to members of three previously delineated age groups: 20' s-30' s, 40's -50's, and 60's and above who are married or have been married at least once and reside in Seoul or Gyeonggi province. A total of 700 questionnaires were analyzed using SPSS and the data were sorted by age group. The results indicate an apparent difference between the husband's side and the wife's side in providing funding for housing at marriage in that a large portion of the funding is provided by the husband's side. Among various funding sources, a cash gift from the couple's parents appears to fund the largest portion of the total cost for housing and marriage. Results show that a cash gift from the couple's parents funds a larger portion of housing expenses for younger generations, a phenomenon that becomes more severe and apparent the younger the couple is.

This paper proposes a simplified algorithm devised to obtain optimal solution to the marriage problem. In solving this problem, the most widely resorted to is the Gale-Shapley algorithm with the time complexity of $O({\mid}V{\mid}^2{\mid}E{\mid})$. The proposed algorithm on the other hand firstly constructs a $p_{ij}$ matrix of inter-preference sum both sexes' preference over the opposite sex. Secondly, it selects $_{min}p_i$ from each row to establish ${\mid}p_{.j}{\mid}{\geq}2,j{\in}S$, ${\mid}p_{.j}{\mid}=1$, $j{\in}H$, ${\mid}p_{.j}{\mid}=0$, $j{\in}T$. Finally, it shifts $_{min}\{_{min}p_{ST},p_{SH}+p_{HT\}$ for $_{min}P_{ST}$ of $S{\rightarrow}T$ and $p_{SH}+p_{HT}$, $p_{HT}<_{min}p_{ST}$ of $S{\rightarrow}H$, $H{\rightarrow}T$. The proposed algorithm has not only improved the Gale-Shapley's algorithm's complexity of $O({\mid}V{\mid}^2{\mid}E{\mid})$ to $O({\mid}V{\mid}^2)$ but also proved its extendable use on unbalanced marriage problems.

Lot-streaming is the process of splitting a job (lot) into a number of smaller sublots to allow the overlapping of operations between successive machines in a multi-stage production system. A new genetic algorithm (NGA) is proposed for minimizing the mean weighted absolute deviation of job completion times from due dates when jobs are scheduled in a no-wait lot-streaming flow shop. In a no-wait flow shop, each sublot must be processed continuously from its start in the first machine to its completion in the last machine without any interruption on machines and without any waiting in between the machines. NGA replaces selection and mating operators of genetic algorithms (GAs), which often lead to premature convergence, by new operators (marriage and pregnancy operators) and adopts the idea of inter-chromosomal dominance. The performance of NGA is compared with that of GA and the results of computational experiments show that NGA works well for this type of problem.

Genetic admixture in human, the result of inter-marriage among people from different well-differentiated populations, has been extensively studied in the New World, where European colonization brought contact between peoples of Europe, Africa, and Asia and the Amerindian populations. In Asia, genetic admixing has been also prevalent among previously separated human populations. However, studies on admixed populations in Asia have been largely underrepresented in similar efforts in the New World. Here, I will provide an overview of population genomic studies that have been published to date on human admixture in Asia, focusing on population structure and population history.

Lot-streaming is the process of splitting a job (lot) into sublots to allow the overlapping of operations between successive machines in a multi-stage production system. A new genetic algorithm (NGA) is proposed for an n-job, m-machine, lot-streaming flow shop scheduling problem with equal-size sublots in which the objective is to minimize the total stretch. The stretch of a job is the ratio of the amount of time the job spent before its completion to its processing time. NGA replaces the selection and mating operators of genetic algorithms (GAs) by marriage and pregnancy operators and incorporates the idea of inter-chromosomal dominance and individuals' similarities. Extensive computational experiments for medium to large-scale lot-streaming flow-shop scheduling problems have been conducted to compare the performance of NGA with that of GA.

This study was conducted to examine the influence of the psychological health of the released offenders on their adaptation to community. Researchers analyzed the survey data of 216 participants who received joint marriage support from the Korea Legal Protection and Welfare Corporation. The results showed that the education level, marriage status, and monthly income were having a positive influence on the community adaptation of the released offenders, and the higher the depression and inter-personality among the risk factors of psychological health, the more negative the community adaptation. A higher sense of self-esteem, a psychological health protection factor, has a positive effect on community adaptation while reducing the influence of risk factors, depression and inter-personality. In sum, high self-esteem can contribute to increasing social life satisfaction after release from prison, promote risk factors to positive life changes, suppress negative situations and increase the possibility of successful community adaptation. Although this study confirmed that self-esteem is the most important factor among psychological factors for successful community adaptation of inmates, it will require relevant follow-up research and multi-disciplinary support because psychological factors alone cannot solve the problem.

Purpose: Sexuality is important for the quality of life in old men, but this issue has been less explored due to social prejudice. Therefore, this study was carried out to describe a correlation between sex life and depression perceived by old men. Method: The subjects were 370 old men who were aged over 60 and lived in a city and three provinces. Instruments used in this study were Perception of Sex life Scale 01 items) and Depression Scale (20 items). The data was collected from December 2001 to February 2002 by written responses of the subjects to the questionnaire as well as one-to-one interview by research assistants for subjects. Statistical analysis for the data was done using SPSS and the level of significance was tested at 95% of confidence interval. Result: 1) Mean age of the subjects was $69.35{\pm}5.70$. A total of 253 subjects (68.6%) had spouse, and 191 of the subjects (52.3%) had sexual intercourse as frequently as 3 times per month. The average score for perception of sex life was $21.25{\pm}5.06$, out of the total score of 44, and that of depression was $35.08{\pm}9.29$ out of the total score of 80. 2) Perception of sex life was statistically significant by age, education, disease, medication, living arrangement, marital status, presence of girlfriend, pattern of inter-coitus, pocket money age of last coitus, subjective health state, and relationship (P<0.05). 3) Depression was statistically significant by age, education, disease. medication, living arrangement, marital status, satisfaction for marriage life, pattern of inter-coitus, feeling for change of sex life, pocket money, subjective health state, and relationship (P<0.05). 4) The correlation between perception of sex life and depression was negative, showing that depression tended to decrease as perception of sex life increases. Conclusion: It is concluded that depression in old men is closely related to their sex life. Positive sex life may have an important effect on the quality of life in old men.

This study aimed to examine nutritional status and similarities of diets between Vietnamese female immigrants and Korean spouses and dietary changes of Vietnamese females after immigration. Subjects were 608 couples visiting 13 medical centers for the Cohort of Intermarried Women in Korea from November 2006 to November 2007. Anthropometric and biochemical measurements were obtained and dietary intakes were assessed using one-day 24-hour recall. Sixty-eight percent of wives answered there have been changes in their diets and consumptions of meats, fish, dairy products, vegetables, and fruits increased after immigration. Energy intakes of wives and spouses were 1491.7 kcal and 1788.8 kcal, respectively, showing most couples (80.1%) consumed less than the Korean estimated energy requirements. More than half of the couples were below the Korean estimated average requirements of zinc, vitamin $B_2$, and folate. The correlation coefficients between couples ranged 0.15-0.38 for unadjusted, 0.22-0.35 for per 1000 kcal, and 0.21-0.40 for energy-adjusted, respectively. The proportions of couples in the same quartiles of each nutrient intake and in the same answers of each question of Mini Dietary Assessment were about 30% across nutrients and around 50% across questions. The length of residence is related to similarities of nutrient intakes between couples: similarities decreased after 3 years of residence in Korea. In conclusion, nutritional intakes of inter-married couples were inadequate although wives reported that their dietary intakes increased after immigration. Inadequate nutrient intakes of wives were partly explained by similar diets between couples because these wives without enough adjustment to Korean culture were more likely to follow what their spouses ate. Findings from this study may be helpful to improve the nutritional status of inter-married couples and make policies and programs for them. A follow-up study should identify factors affecting inadequate nutritional status of intermarried couples and similarities of their diets.
