As a case study, this paper historicizes the film culture in Namchon district in Keijo(京城) based on a preliminary research on the film ephemera produced during the colonial period. Through cross-examining articles appeared in Japanese newspapers and magazines at the time, this paper empirically reconstructs the Japanese settlers' film culture in Keijo, a colonial city whose cultural environment was ethnically divided into 'Bukchon' and 'Namchon.' During the silent era, movie theaters in the Namchon district not only played a role of cinema chain through which films imported and distributed by Japanese film companies were circulated and exhibited but also served as a cultural community for Japanese settlers who migrated to a colony. The film ephemera issued by each theater not only provided information about the movie program, but also connected these Japaneses settlers in colonial city, Keijo to the homogeneous space and time in Japan proper. Both as a minority and colonizer in a colony, these Japanese settlers experienced a sense of 'unity' that could 'distinguish' their ethnic identity differentiated from Koreans through watching movies in this ethnically segregated cultural environment. In doing so, they were also able to connect themselves to their homeland in Japan Proper, despite on a cultural level. This is a cultural practice that strengthens a kind of long distance nationalism. Examining Japanese film culture through film ephemera would not only contribute to the previous scholarship on modern theater culture and spectatorship established since the 2000s, but also be a meaningful attempt to find ways and directions for film history research through non-film materials.

Compound K (20-O-β-(_D-glucopyranosyl)-20(S)-protopanaxadiol) is an active ingredient of ginsenosides. Compound K has been known to produce from biotransformation by β-glucosidase action of human intestinal microbes after oral admistration of ginseng. We have investigated the cytotoxicity of compound K obtained from bio-converted ginseng extract. As a result, compound K showed no significant cytotoxicity in the concentration of 0.001 to 1 ㎍/mL and inhibited the production of TNF-α, MCP-1, IL-6 and NO in RAW 264.7 cells induced by LPS inflamation. In the same concentration, HaCaT cells induced by inflammation with TNF-α and IFN-γ decreased IL-8 production due to compound K treatment. In the brine shrimp lethality assay, the LC₅₀ of compound K was 0.37 mg/mL indicating some toxicity, but the bioconverted product containing 35% compound K showed relatively low toxicity with an LC₅₀ of 0.87 mg/mL. These results suggest that the compound K enriched extract is a potential functional material for acne relief cosmetic products.

We fitted latent growth models of attitude towards science using the Korea Education & Employment Panel 2004-2007 data with 343 high school students. The growth model show better fit indices compared to the no growth model. The intercept and slope showed significant variances, and thus, we added control variables of the number, ratio of advanced courses, and variety in science elective subjects, and the achievement percentile for middle school. In the conditional growth model, the previous achievement has significant positive effects on the intercept and the ratio of the advanced courses and variety of science subjects show significantly positive effects on the slope. Based on the results, it supports the 2022 Revised Science Curricular that high school credit system should provide students with basic 'Physics,' 'Chemistry,' 'Biology,' and 'Earth Science,' credits in 'general electives', various integrated subjects in 'converged electives', and highly advanced subjects in 'career electives.'

To investigate the taxonomic status of undescribed species Acheilognathus sp. HR from Korean Acheilognathidae discovered from the Dalcheon River, a tributary of the Hangang River, molecular phylogenetic and morphological characteristics were compared and analyzed with previous studies. As a result of molecular phylogenetic analysis, A. sp. HR formed the same genetic clade as the five subspecies of Acheilognathus tabira, but formed a separate monophyletic group based on the unique genotype, showing clear differences. As a result of morphological analyses, the dorsal fin color in males is grayish and the nuptial coloration of the outer edge of the anal fin is white. The outer edges of the dorsal and anal fins are convexly rounded. A black blotch is present on the dorsal fin of the juvenile, but there is a black blotch absent on the dorsal fin of the small adult female. In the counts, the number of branched dorsal rays is 12~13. In the measurements, the length of the barbels is short and the body depth is deep. Therefore, the A. sp. HR of Hangang River is considered at the level of a distinct species distinguished from each other by the five subspecies of A. tabira by molecular phylogenetic, morphological, and limited distributional characteristics.

The movie Lolita is directed by the famous director Stanley Kubrick in the United Kingdom in 1962. Due to the movie theme, it produced a great social dispute at that year. Lolita was Stanley Kubrick's first independently produced film. It tells the story of the abnormal love between Professor Humbert from Europe and his stepdaughter Lolita. Throughout the film, it shocked people by feeling honourable and aesthetic although the theme is about commit incest. The director also completely shown the social reality of the United States in a black humor irony method. By the meantime, the lush tragic feature of the film also strongly infects the audience. Current studies on the movie Lolita mainly focus on the following aspects: firstly, the black humor techniques of director Kubrick's movies, secondly, the parody techniques of the movie, and thirdly, the differences between the original novel Lolita and the adapted movie. In the American society where consumerism constitutes the mainstream, instead of sticking to traditional moral concepts, people pursue material enjoyment. Based on the consumerism theory, this paper analyzes the social reality revealed by the movie Lolita, presents such typical characteristics of the consumerist society as hedonism and broken family relations, and explains how the consumerist society leads to Lolita's tragic life.

This study was conducted to explore and understand the meaning of stigma of families having old people admitted to nursing home within the Korean culture. Data collection was performed through in-depth interviews and participant observations which were recorded and transcribed verbatim with the consent of the participants. The key informants were 12 people having the aged family member in nursing home. The data was collected from October 2008 to February 2009 until completed. Data were analyzed utilizing the taxonomic analysis method developed by Spradley. As a result, 24 themes, 8 categories and 4 cultural domains are founded from the cases. The cultural domains resulted from the analysis are: 『Incompetence of Oneself: 'Adaptation to Inevitable Realities', 'Difficulty of Economic Independence', 'Difficulty of the Subjective Self-assertion'』, 『Contradictoriness of Decision Making: 'Decision Making Different from Own Mind', 'Conflicts between Neighboring'』, 『Self-rationalization of Decision Making: 'Self-comfort of Decision Making'』, 『Shifting Responsibility: 'Services Different from that of Family', 'Laking in Sincerity of Responsible Institution'』. Theoretical model about stigma of the family having old people admitted to nursing home by the research result in the above was able to be confirmed that it was expressed with the original form of thought of recursive system which continuously showing the inconsistency of decision making, rationalizing decision making, and shifting one's own responsibility in the process of accomplishing the duty of supporting old people. Based on the results, I discussed the meaning of stigma of families having old people admitted to nursing home and provided recommendations for future research.

We wanted to develop a real-time PCR assay capable of detecting Liobagrus obesus in environmental DNA (eDNA) extracted from freshwater samples using a pair of species-specific primers and probe for the endangered fish, L. obesus. The species-specific primers and probe were designed in consideration of single nucleotide polymorphisms between 65 species of freshwater fish living in the Republic of Korea within the cytochrome b (cytb) gene of mitochondrial DNA. The species-specific primers and probe, in the real-time PCR assay, showed high specificity as only the L. obesus genomic DNA (gDNA) was found to be positive in the specificity verification using 65 species gDNA of freshwater fish in the Republic of Korea. In addition, in the detection limit analysis using the serial dilution concentrations of L. obesus gDNA, it was found that it was possible to detect up to 0.2 pg, showing high sensitivity. Afterwards, using the species-specific primers and probe, real-time PCR assay was performed on freshwater samples obtained from 8 stations in the mid-upper basin of Geum River. As a result, the cytb gene of L. obesus was detected in total 5 stations including all 3 stations where this species was collected at the time of field survey. Therefore, the species-specific primers and probe developed in present study, and the real-time PCR assay using them, can accurately detect the cytb gene of L. obesus from eDNA samples, which can be utilized to monitor the existing habitats of this species and to discover potential new habitats.

Growth and seed productivity of black soybean (cv. Cheongja-3ho) sown on four different dates were investigated in paddy fields in the southern region to cope with climate change, trends in consumption of soy foods, and the spread of double cropping region. Sowing date of black soybean showed a significant correlation with above-ground growth, seed yield, useful components, etc. When sown in May, the above-ground part was plentiful, while seed yield significantly decreased. On the other hand, when sown in June and July, reproductive growth was vigorous resulting in high seed yield, exceeding 200 kg/10a, and pod injury and seed coat cracking were reduced. Furtherm ore, the isoflavone content of seed increased significantly as the sowing date was delayed. These results suggests that sowing from early June to early July is appropriate. Nevertheless, late June sowing oppears the m ost appropriate for black soybeans in the southern paddy fields, in order to avoid a risk of overlapping with sowing dates of winter crops in the double cropping.

The 886-bp sequence of the mitochondrial region encoding the cytb gene was used to identify the origin of the Goryeong (GR) population of Pungitius kaibarae and to characterize genetic diversity and structure among wild populations. The GR population showed the lowest haplotype diversity (H_d=0.000), while the highest haplotype diversity was confirmed at 0.755 among the Goseoung (GS) population. Nucleotide diversity ranged was the highest diversity at 0.00291 in the GS population and the lowest diversity at 0.00000 in the GR population. The GR population was genetically closest to the Pohang (PH) population. The haplotype network confirmed that the GR population was most similar to the PH population. The GR population also clustered with the PH population with high bootstrap support (98%) in a phylogenetic tree. We thus conclude that the GR population is derived from a population similar to the PH population.
