The purpose of this study was to examine what characterized the family of origin among couples who had been married just for a few years, what types of conflicts they suffered, how they tackled their conjugal conflicts, what sorts of counseling services they needed in times of conjugal conflicts and how the characteristics of their families of origin and marital conflicts affected their needs for counseling. The findings of the study were as follows: First, regarding family rules and regulations, the biggest characteristic among the families of origin of the married couples investigated was that they were most aware of rules for living. The husbands were more conscious of them than the wives. Concerning their marital conflicts in each area, their conflicts were most triggered by their own personal characteristics, followed by communal life, a third person and their own conjugal relations. Second, as for their needs for counseling, the married couples were highly willing to ask for counseling in times of conflicting with each other. Third, concerning their perception of the rules of the family of origin, the husbands were more cognizant of then Fourth, regarding connections between needs for counseling and family rules, the group whose family of origin placed stronger emphasis on rules for living felt the higher needs for counseling. It's attempted in this study to provide information about counseling for married couples, on which few domestic studies have ever focused so far, and the effort to take a micro approach toward the counseling needs of married couples made it clear that their counseling needs might be different according to their family background variables and their own marital conflicts.

This work aimed to evaluate 11 potato families for insect resistance horticultural traits. The families were derived from crosses between introduced insect resistant and adapted genotypes. A randomized complete block design, with three replications was used. The plot consisted of 25 genotypes of a family, summing up to 75 genotypes tested per family. Two susceptible cultivars were included in the experiment as checks. The genotypes were evaluated for insect resistance, tuber yield traits, tuber appearance and tuber skin smoothness. The genetic value for the intensity of insect attack in the leaves and in the tubers was lower(higher resistance) in the 11 families than in the checks. For yield traits, there was no predominant effect among the families regarding the origin of the resistant donor species(Solanum berthaultii and/or S. chacoense). However, there was a large contribution of the C-1485-16-87 recurrent parent in crosses with resistant genotypes for tuber yield and tuber number. In relation to tuber appearance, only the family derived form the C-1485-16-87/ ND140(S. berthaultii) cross did not differ from the checks. had genetic value tuber skin smoothness, it was identified that families derived from S. berthaultii resistant parents showed higher genetic values than the check cultivars. For tuber skin smoothness, the genetic values of the families neither differed significantly from each other nor from the checks.

This is the first report of Snyderina yamanokami, from the subfamily Tetraroginae of the family Scorpaenidae, collected in Korea. The specimen (175.3 mm long) was caught in the coastal waters of Jeju Island on a commercial longline hook on 9 September 2009. This species is characterized by the following morphological traits: 9-11 dorsal fin rays, 5-6 anal fin rays, 13-15 pectoral fin rays, 5 ventral fin rays, pectoral fin tip reaching or extending past the origin of the anal fin, palatines toothless, and four dark spots on the middle of the body. We suggest a new Korean name, "Keun-mi-yeok-chi," for S. yamanokami.

Background: Due to the rapidly changing climatic conditions, South Korea faces the grand challenge of exotic species. With the increasing human movement, the influx of alien species to novel regions is prevalent across the globe. The latest research suggests that it is easy to prevent the introduction and establishment of alien species rather than controlling their spread and eradication. Like other countries, the Korean Ministry of Environment released a list (in 2018) of 45 potential risky exotic fish species considered likely to be invasive candidate fish species if they ever succeed in entering the Korean aquatic ecosystems. Results: The investigation into the invasion suitability traits showed that potential risky fish species could utilize those features in becoming invasive once they arrive in the Korean aquatic ecosystems. If the novel species establish viable populations, they are likely to incur higher economic costs, damage the native aquatic fauna and flora, and jeopardize the already perilled species. Furthermore, they can damage the installed infrastructure, decline overall abundance and biodiversity, and disturb the ecosystem services. Here we reviewed the list of fish species concerning their family, native origin, preferred aquatic biomes, main food items, current status in Korea, and potential threats to humans and the ecosystems. Data shows that most species are either already designated as invasive in the neighboring counties, including Japan, Vietnam, Thailand, and China, or originate from these countries. Such species have a higher climate match with the Korean territories. Conclusions: Therefore, it is exceptionally essential to study their most critical features and take regulatory measures to restrict their entry. The incoming fish species must be screened before letting them in the country in the future. The regulatory authorities must highlight the threatening traits of such species and strictly monitor their entrance. Detailed research is required to explore the other species, especially targeting the neighboring countries fish biodiversity, having demonstrated invasive features and matching the Korean climate.
