The purpose of this study was to investigate the influences of high school students' sexual media literacy awareness and sexual attitude on their gender sensitivity. The subjects of this study were 120 high school students in the city of D, all of who voluntarily agreed to participate in the study. Data were collected from November 28 to December 15, 2022. and analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and hierarchical regression analysis methods using the SPSS 22.0 program. As a result of the study, the influential factors of gender sensitivity were sexual attitude (β=-.317, p<.001), education level of father (β=.305, p<.001), gender (β=.262, p=.001), source of sexual knowledge (β=-.252, p=.001) and awareness of sexual media literacy (β=-.143, p=.045). This study is significant in that it presents academical, practical, and policy recommendation to increase gender sensitivity, which is considered an essential competency in a future society where diversity is emphasized.

Cornus controversa is a long-lived woody species mostly distributed in East Asia. Random amplified polymorphic DNA (RAPD) markers were used to investigate the genetic diversity and population structure of Korean populations of this species. A high level of genetic variation was found in seven populations of C. controversa. The mean genetic diversity (H) was 0.222 across populations, varying from 0.200 to 0.238. Eighty of the 93 loci (86.0%) showed detectable polymorphism in at least one population. Total genetic diversity values ($H_T$) varied between 0.192 and 0.231, giving an average overall polymorphic loci of 0.212. The interlocus variation of genetic diversity within populations ($H_S$) was high (0.167). Mean of genetic diversity in C. controversa was higher than average values for species with similar life history traits. The sexual reproduction, perennial habitat, and longevity are proposed as possible factors contributing to high genetic diversity. On a per locus basis, the proportion of total genetic variation due to differences among populations ($G_{ST}$) ranged from 0.169 to 0.278 with a mean of 0.216, indicating that about 21.6% of the total genetic variation was among populations. An indirect estimate of the number of migrants per generation (Nm=1.893) indicated that gene flow was extensive among Korean populations of C. controversa.

This study analyzed the expressive characteristics of padding in contemporary fashion. The methodology of this study was quantified through documentaries, fashion collections, and internet news. The results of expressive characteristics and methods were as follow. First, variability showed the creation of dwelling space by air filling, detail mode by zipper, and diversity of recycled filling by zipper pocket. It reflected the pursuit of nomadism and subversion of permanence by change of filling. Second, it was sexual symbolicity that showed the blurred androgynous silhouette by air filling and padding bar design of the chest, stomach, shoulder for the male body silhouette. It emphasized male sexual identity and power through the expression of a modern ideal body. Third, decoration displayed various crafts (such as knitting), various fabric such as polapolis, suedette, corduroy, denim, leather, knit, and spangle. It reflected visual pleasure, scarcity and various interpretations. Fourth, playfulness character forms throug hair filling, unfamiliar fashion items, diversity of silhouette and change of uses. It reflected a pleasant feeling through astonishment and surprise, nostalgia involved in memory and childhood play and disembarrassment from reality. Fifth, simplicity showed the elimination of a sportswear's factor with regular wad quilting, elimination of wad quilting, wad quilting following the structural line of clothes and the structual line of clothes omitted. It reflected disembarrassment from stereotype and an emphasis on essential elements.

The purpose of this study was to explore sexual behaviors among adolescents in multicultural families in Korea. The data were obtained from the 15th Korea Youth Risk Behavior Survey 2019. Complex-sample descriptive statistics and the chi-square test were used for data analysis in SPSS 25. Among adolescents in multicultural families, 8.2% reported having sexual experience. Condoms were the most commonly used contraceptive method, and most adolescents received sex education at school. Their likelihood of sexual experience differed according to grade, academic achievement, economic status, residential area, perceived stress, and drinking and smoking experience (p<.001). The results of this study suggest that sex education should be conducted with appropriate consideration of the important factors associated with adolescents in multicultural families.

Avian vocalization has been main topics in studying animal communication. The structure and usage as well as development and function of vocalization vary enormously among species and even among populations, and thus we reviewed the general patterns of song learning and the consequences of song communication in birds at the behavioural level: first, we compared the different learning phenomena between non-songbird and songbird, and we investigated the learning process of songbird both in the field and in the lab, which are needed to fully understand vocal communication. Second, we discussed a recent trend of sexual selection hypothesis explaining the structural and functional diversity of song in songbirds with repertoire and presented how the repertoire is actually used between neighbours based on individual recognition.

Kalopanax pictus is a long-lived woody species mostly distributed in East Asia. K. pictus has been regarded as medically and ecologically important species in Korea. Thornless castor aralia variant, local name 'Cheongsong' is an endemic to Cheongsong province in Korea. Random amplified polymorphic DNA (RAPD) was used to investigate the genetic variation and structure of Korean populations of two species. A high level of genetic variation was found in six K. pictus populations. Twelve primers revealed 49 loci, of which 29 were polymorphic (59.2%). Nei's gene diversity for K.pictus and K. pictus variant were 0.119 and 0.098, respectively. Mean of genetic diversity in K. pictus was higher than average values for species with similar life history traits. The asexual and sexual reproduction, perennial habitat, and longevity are proposed as possible factors contributing to high genetic diversity. An indirect estimate of the number of migrants per generation (Nm=0.857) indicated that gene flow was not extensive among Korean populations of K.pictus. It is suggested that the isolation of geographical distance and reproductive isolation between K.pictus and K.pictus variant populations may have played roles in shaping the population structure of this species.

Northern pipevine (Aristolochia contorta) commonly inhabits marginal areas between waterside and terrestrial vegetation. In particular, A. contorta is ecologically important in the marginal areas as a food plant of dragon swallowtail butterfly (Sericinus montela), which is designated as vulnerable species in the Republic of Korea. For long-term sustainability of the plant population, assessment of the genetic diversity of exist populations should be conducted. Genomic DNA of A. contorta leaf samples were extracted from four populations where the vigorous growth were observed in the South Korea. Intra-population genetic diversity and inter-population genetic distance were assessed using randomly amplified polymorphic DNA (RAPD) with five polymorphic random primers. Overall genetic diversity was lower, compared to other wetland species (h: 0.0607 ~ 0.1401; I: 0.0819 ~ 0.1759), while GP showed the highest intra-population genetic diversity. Despite of the geographical distance, GP showed the larger genetic distance from other populations. This result seemed to be caused by the fragmented habitat and lower sexual reproduction of A. controta. Mixture of the different source populations and construction of the proper environmental condition such as shade and physical support for sexual reproduction should be considered for conservation of A. contorta population.

Purpose: This study investigated Korean healthcare providers' attitudes toward sexual and gender minority (SGM) persons and their knowledge and behavior concerning the collection of data on sexual orientation and gender identity (SO/GI). Methods: In this cross-sectional, descriptive study, 137 Korean healthcare providers were recruited through convenience sampling from internet communities for medical professionals. A structured questionnaire was created using Google Surveys. The Mann-Whitney U-test, Kruskal-Wallis test, and Spearman correlation analysis were performed. Results: The sample was mostly women (80.3%) and nurses (83.9%), who had overall negative attitudes toward SGM persons and low levels of knowledge and behavior with regard to the collection of patients' SO/GI data. Participants in their 20s, who were religious, and had clinical experiences in treating or providing nursing care for SGM persons had higher levels of knowledge about the collection of SO/GI data. The level of engagement in collecting SO/GI data was higher among women and in their 20s and 30s, unreligious participants, nurses, and those with less than 10 years of clinical experience. Positive attitudes toward SGM persons were associated with higher levels of knowledge, but lower levels of behavior, regarding the collection of SO/GI data. Conclusion: It is important to recognize the diversity of patients' SO/GI and to collect the corresponding information. To this end, it is necessary to develop and use a standardized SO/GI form. Healthcare providers should also receive education and training related to the health of SGM persons to resolve health problems that disproportionately affect SGM persons and related health disparities.

A harpacticoid copepod, Microarthridion littorale (Poppe, 1881), is newly recorded in Korea. Microarthridion species can be distinguished from each other by a combination of the number of the antennular segment, the number of the seta on the antennary exopod, and the armature of the thoracopod legs. Korean materials examined coincide well with M. littorale on these well-known characteristics. However, there are some minor differences in the ornamentations of the maxilliped and swimming legs. The specimens show additional sexual dimorphisms in the setae on enp-3 of P1 and exp-3 of P2-P4. Morphological diversity of so-called M. littorale is also discussed here with detailed features.

The genetic diversity and population structure of Potentilla freyniana in Korea were determined using genetic variations at 19 allozyme loci. Thirteen of the 19 loci (68.4%) showed detectable polymorphism. Genetic diversity at the population level was high ($H_{EP}$ = 0.270). Total genetic diversity values ($H_T$) varied between 0.190 and 0.584, giving an average overall polymorphic loci of 0.371. The interlocus variation of genetic diversity within populations ($H_S$) was high (0.354). On a per locus basis, the proportion of total genetic variation due to differences among populations ($G_{ST}$) ranged from 0.008 for Fe-2 to 0.310 for Gpi with a mean of 0.065, indicating that about 6.5% of the total allozyme variation was among populations. Wide geographic ranges, perennial herbaceous nature and the persistence of multiple generations are associated with the high level of genetic variation in P. freyniana. The estimate of gene flow based on $G_{ST}$, was high among Korean populations of P. freyniana (Nm =3.57). Although P. freyniana usually propagated by asexually-produced ramets, I could not rule out the possibility that sexual reproduction occurred at a low rate because each ramet may produce terminal flowers.
