Apologies are used with increasing frequency for mending damaged relations between groups after intergroup conflict. Past research revealed that members of a perpetrator group may engage in (animalistic) dehumanization of victim group members to cope with guilt and responsibility associated with the ingroup's past wrongdoing. We hypothesized that ingroup's apology would relieve perpetrator group members of the moral threat, and therefore would make them perceive more humanness in the victim group members. The study was conducted in the context of South Korea's alleged atrocities against Vietnamese civilians during its military involvement in the Vietnam War. Korean participants read an article on the incidents with Korean government's issuance of an official apology manipulated, and reported their thoughts on the incidents and perceptions of Vietnamese people including their humanness. Contrary to our prediction, apology further enhanced dehumanization of Vietnamese people, even while it also decreased dehumanization through heightened feelings of relief. This study documents a seemingly ironic effect of intergroup apology, and calls for a more careful examination of the consequences of apology before recommending it as a viable strategy for alleviating intergroup tensions.

This study investigated the electrical conductivity, pH, and diastase activity characteristics of 31 types of domestic and imported honey, which are not currently used in the Korean honey grading system, to determine the feasibility of introducing these indicators into the honey grading system. The results showed that the moisture content of domestic and imported honey is around 20%, indicating that domestic quality standards are relatively well controlled, and the pH values are distributed in the range of pH 3.91 to 6.31. The electrical conductivity of domestic and imported honey ranged from 0.09-1.51mS/cm, which showed a large difference between the samples. Although there was a large difference of electrical conductivity from the honey types, further research is needed to determine whether it is applicable to Korean honey. Finally, in the case of diastase activity, Korean honey showed relatively high DN values compared to imported honey from Vietnam, New Zealand, the United States, and China. Therefore, diastase activity is an important indicator for evaluating the quality of honey, and further research is needed to confirm its feasibility as an additional indicator for the domestic honey grading system in Korea. This study evaluated the physical properties and enzyme activity characteristics of domestic and imported honey, and is expected to provide basic information for the establishment of a honey grading system, thereby improving consumer trust in the honey grading system and enhancing the development of honey distribution in Korea.

Recently, as an enonomic importance of the Eurasian Continent raises, the necessity of east-west connecting ancient transport roads research is increasing. Although domestic research of eastern-western international exchange in the Eurasia is not yet very active, the studies of history, archaeology, art history, folklore, costume history have been advanced steadily. An attention for the exchange through steppe route originated from the interest in Korean folk and Korean culture and the research range is extending to Xiungnu, Kurgan culture as a direct investigation on the remains of Mongolia and Kazakhstan has been achieved constantly. The art history has been leading the research of exchange which is based on desert and oasis. The field research of Iran, Uzbekistan, Azerbaijan, etc progressed in various routes, and the research on diverse topics including Silla's golden culture, transmission of glass, and the Buddhism is improving. Research on the maritime silk road is weaker, compared to other parts. Buddhist and Hindu temples of Southeast Asia attracted some interest to people, but the research should focus on the restoration of sea route and consideration of its meaning. Research of this part is expected to be more activative, as domestic researchers investigate Don Son culture and Sa Huynh culture of Vietnam by themselves. From now on, we should focus on topics that are not directly connected to Korean history, and Korean culture. Because it is also our duty to study and conserve the culture of entire human community.

South Korea is the representative consumption country of herbal medicines and most of herbal medicines circulating in Korea have been importing from the developing countries of Southeast Asia such as China, Vietnam, Indonesia and so forth. Domestic hygiene and safety are continuously proposed because herbal medicines which are circulating have the possibility could remain contaminants or residues. Physicochemical contaminants such as heavy metals, persistent organic pollutants, radionucleosides, microbial toxins, biological contaminants such as microorganisms and animals, agrochemical residues such as pesticides, substances used for fumigation, antiviral agents, and solvent residues are classified as major contaminants and residues in herbal medicines from 2005 September WHO.$^{1)}$ Currently our administration have established a permission standard and the inspection criteria against the heavy metal, the residual pesticides and a residual sulfur dioxide. Furthermore our administration is continuously monitoring and conducting researches for the policies and their scientific ground against herbal medicines. But the appearances or discoveries of the harmful new species due to environmental and industrial developments are becoming social problems. Therefore it may be necessary to continuously consider and investigate regarding hereupon. Recently, the contamination of the mycotoxins against foods such as cereals, nuts and the powdered red pepper have developed and started became problematic issue, and possibility of contamination against the herbal medicine is proposed. And since populations who are using the herbal medicines very limited to several nations, recognition and researches about contamination of mycotoxins in herbal medicines are very insufficient. Therefore it will be need to more focus on the international regulation of quality control and safety for herbal medicines. Now on, we are going to introduce the importance, occurrence, characteristic properties, World-wide research trends and detoxification of aflatoxins, which is known as the most potent mutagen, carcinogen and teratogen mycotoxins.

The brown planthopper, Nilaparvata lugens, is among the most serious insect pests of rice. It is widely distributed in Asia, Australia and Pacific islands. An earlier mitochondrial DNA study revealed that there exist significant genetic differences between populations north and south of the Red River Delta region in Vietnam. However the mitochondrial DNA was not sufficiently variable to examine the sources of immigration. For a more detailed analysis of geographic population structure of N. lugens, we developed microsatellite markers. Thirty-seven putative microsatellite loci were isolated using a magnetic biotin method, and five primer pairs designed from the flanking regions of sequenced microsatellite clones were labeled with fluorescent. Of these five primer sets, two have proven to be useful across all the samples we used in this study. We used variation at these two microsatellite loci to test the hypothesis that N. lugens biotypes (1, 2, and 3) sampled from laboratory selection constituted distinct genetic units. Allele frequency differences among the three major biotype categories were not significantly different at one locus (27035). However, the other (7314) did show differences among the major three biotypes. The methods we describe here will be useful for studying population structure of crop pest and for tracking the patterns of migratory pest like the rice planthoppers.

Purpose: The purposes of this study were to develop a postpartum nursing intervention program for immigrant women and evaluate the effects on postpartum depression, child rearing confidence, home environment, and infant temperament. Methods: This research was a non-equivalent control group pre-test and post-test design. Participants were pregnant immigrant women from China, Vietnam, and the Philippines residing in Kyunggi province and Seoul. Twenty women were assigned to the intervention group, and 19 women to the control group. For the intervention group, the women were visited at home and provided emotional support and parenting education for three months. To analyze the intervention effects, repeated measure ANOVA and t-test were used. Results: Child rearing confidence was higher in the experimental group than the control group at interaction effect of time and group, six weeks and three months postpartum. However, there were no significant effects for maternal depression, infant temperament, and husband support. Home Observation for Measurement of the Environment (HOME) score in the experimental group was higher than that of the control group at three month postpartum. Conclusion: Results indicate that the nursing intervention program had positive effects and can be used to further the health status of immigrant mothers and children.

International marriage migrants from developing to developed countries are to seek a better economic condition. There are only a few empirical research on comparing and analyzing economic condition of marriage migrants before and after marriage. This study attempted to analyze the relationship between the cognition on the change of economic condition before and after marriage and the socio-economic characteristics of Vietnamese international marriage female migrants. About 80% of interviewees of this study were motivated to marry Korean men for economic reasons; however, their household economic level was relatively low. Reflecting the household economic level, about half the Vietnamese women considered that there was very little difference in the economic condition before and after marriage; while, the percent of women considering the current economic condition as getting better were more than 4 times of that of women considering as becoming worse. The cognition on the economic condition change before and after marriage was positively correlated with the level of education attainment of husbands and themselves, the Korean language ability, state of occupation in Korea, the level of husband's income, involvement of management of living expenses and length of residence in Korea. The occupation in Vietnam and the state of remittance were not significantly related to the cognition on the economic condition change before and after marriage. Vietnamese marriage female migrants were highly motivated to have a job out of home to improve the economic condition of their own family and natal family. Concreted alternative programs should be made to help those women to work out of home.

Purpose: The aim was to collect and classify the Cordyceps parasitized in cicadas from July to October every year from 1990 to 2016 in Korea. And they were frequently collected in Nepal, Vietnam, Japan, China, and Thailand. Methods: Cordyceps parasitizing cicadas collected in mountains and fields. Results: A total of 1,104 specimens were collected that belonged to 10 different species under nine genera. The highest number of samples belonged to Ophiocordyceps (563 specimens), followed by Isaria (361 specimens), Polycephalomyces (73 specimens), Cordyceps (70 specimens), Beauveria (25 specimens), Perennicordyceps (8 specimens), Metarhizium (2 specimens) and Purpureocillium (2 ones). Among Ophiocordyceps spp. O. longissima was most frequently collected with a total of 426 samples out of 563, followed by O. heteropoda with 120 ones and O. sobolifera with 17 specimens. The species mainly collected in Korea, but C. ishikariensis was collected in Nepal only. The new characteristic was that Isaria cicada-like synnemata were found growing together with C. ishikariensis stromata on the same host. In Korea, the collected 691 specimens in total out of 1,104 were found in Mt. Halla in Jeju Island. Other mountains in Korea where the samples were collected were Mountains Daeryong, Jiri, Yongmoon, Samag, Seolag, Gujeol, Duryun, Baegam, Chilgap, Chundeung, Naejang, Welchul, and Daeryong. The three samples were not identified. Conclusions: A total of 1,104 specimens belonged to 10 different species under nine genera, and the collected 691 samples were found in Mt. Halla in Jeju Island.

This study analyzed the spatiotemporal evolution of Korean multinational corporations' (MNCs') foreign direct investment (FDI) networks from 1978 to 2023, focusing on Samsung Electronics and LG Electronics. Using data on the consolidated overseas subsidiaries of these two companies, a two-mode network was constructed to examine the status of host countries through the betweenness centrality index and to identify types of countries with similar value chain arrangements by investigating their linkage structures. The main findings are as follows. First, during the early phase of Korean electronics MNCs' overseas expansion in the 1980s, they primarily established sales bases in developed consumer markets. However, over time, they gradually expanded into other business areas, including manufacturing, producer services, and R&D, increasing complexity in their FDI networks as cross-border mergers and acquisitions (M&As) became more frequent. Second, the United States has remained central to these MNCs' FDI networks since the 1980s, but more recently, China has emerged as a significant hub, challenging the U.S. in global value chains. Third, emerging Asian economies, including India, Vietnam, and Indonesia, have strengthened their positions due to the diversification of MNCs' investment objectives from manufacturing bases to a broader range of business areas. Finally, since the 2010s, the convergence of the electronics industry with the automotive electronics sector and new industries has led to a diversification of the value chain arrangements of Korean electronics MNCs.

Obesity is the leading metabolic disease in industrialized countries and is closely associated with coronary heart disease, hypertension, diabetes, and cancer. The objective of this study was to evaluate the anti-adipogenic effects of two roasted coffee beans, Vietnam robusta (VR) and Ethiopia Mocha Sidamo G2 (ES), as well as fermented coffee beans with Monascus ruber (MR) mycelium on differentiation of 3T3-L1 preadipocytes. Treatments with 1,000 ${\mu}g/mL$ of hot water extract from coffee beans significantly reduced intracellular lipid accumulation. In addition, VR more effectively inhibited transcription factors such as $PPAR{\gamma}$, $C/EBP{\alpha}$, FAS, and aP2 compared to ES. Further, ES fermented with MR showed more effective anti-adipogenic activity than non-fermented ES. These results suggest that VR and ES inhibit adipocyte differentiation which may contribute to their anti-adipogenic properties.
