  • BACKGROUND/OBJECTIVES: Unhealthy food choices among young adults are common globally, and the incidence of chronic diseases, such as obesity, is rising. Food literacy (FL) is important for improving and maintaining individual health in a rapidly changing food environment and can form the basis for following a sustainable diet. Therefore, it is essential to improve FL among young adults, particularly college students, who are in the formative years of their lifelong food habits. This study examined the facilitators and barriers of FL and related dietary behavior among college students in South Korea. SUBJECTS/METHODS: This study recruited 25 college students with different residence types using convenience and snowball sampling. In-person, telephone, and video interviews were conducted from March to November 2021. The interview data were analyzed using framework analysis based on the socio-ecological model. RESULTS: At the individual level, prior good experiences with food were the most frequently mentioned facilitator. In contrast, the major barriers were a lack of knowledge, financial hardship, irregular schedules, and academic stress. At the interpersonal level, the influences of family and peers, such as early exposure to healthy eating habits and opportunities to have easy accessibility to farms and farming, are major facilitators, but the lack of a sense of community was the major barrier. At the environmental level, the major barriers were unfavorable food environments at home and in neighborhoods, such as the absence of kitchens in housing and large packaging of produce at markets. CONCLUSIONS: Many factors affected the students' FL and related healthy eating practices. These findings suggest that a campus-based FL program should be developed by reflecting on these facilitators and barriers.

  • This study was conduct to compare the efficacy to produce male and female somatic cloned piglets. Maturation of porcine COCs was accomplished by incubation in NCSU-23 medium supplemented with 0.6 mM cysteine, 10% porcine follicular fluid, 1mM dibutyryl cyclic adenosine monophosphate (dbc-AMP, Sigma, USA), and 0.1 IU/ml human menopausal gonadotrophin (hMG, Teikokuzoki, Japan) for 20h and then cultured without dbcAMP and hMG for another 18 to 24 h. Female and male fetal cells were isolated from each fetus, cultured in ES-DMEM medium containing 10% FCS. Enucleated oocytes were fused with fetal fibroblasts (passage 4 to 15). Reconstructed embryos were cultured in NCSU-23 with 4 mg/ml BSA under mineral oil at 39$^{\circ}C$ in 5% $CO_2$ in air. A total of 12,328 nuclear-transferred embryos (1- to 4-cell stage) were surgically transferred into 69 surrogate gilts. Three recipients aborted during the period of conception. Three gilts delivered eleven female piglets, and five recipients gave rise to birth 22 male piglets. The average birth weigh of the cloned piglets was 1.52 kg (1.38~1.83 kg) in female piglets and 0.84 kg (0.45~1.25 kg) in male piglets. Alive cloned pigs was seven in female piglets (63.6%) and four in male piglets (18.2%). The other two recipients is ongoing. This study suggests that female-derived fetal cell as a nuclear donor has more capability on production of cloned piglets than male.

  • Purpose: This study was to investigate errors of death certificate (DC) issued for patients with trauma. Methods: A retrospective review for DC issued after death related to trauma at a training hospital trauma center was conducted. Errors on DC were classified into major and minor errors depending on their influence on the process of selecting the cause of death (COD). All errors were compared depending on the place of issue of DC, medical doctors who wrote the DC, and the number of lines filled up for COD of DC. Results: Of a total 140 DCs, average numbers of major and minor errors per DC were 0.8 and 3.7, respectively. There were a total of 2.8 errors for DCs issued at the emergency department (ED) and 5.4 errors for DCs issued beyond ED. The most common major error was more than one COD on a single line for DCs issued at the ED and incompatible casual relation between CODs for DCs issued beyond ED. The number of major errors was 0.5 for emergency physician and 0.8 for trauma surgeon and neurosurgeon. Total errors by the number of lines filled up for COD were the smallest (3.1) for two lines and the largest (6.0) for four lines. Conclusions: Numbers of total errors and major errors on DCs related to trauma only were 4 and 0.8, respectively. As more CODs were written, more errors were found.

  • Purpose: This study was conducted to investigate how one's motive to choose a major of study, career values, and satisfaction with the major affect immersion within the major. Methods: A self-administered questionnaire on choice of major and career values was completed by 224 students from March 2nd to March 15th of 2022. The collected data were analyzed using several metrics and tests with IBM SPSS Statistics 22.0 software: frequency and percentage, mean, standard deviation, t-test, ANOVA, correlation analysis, and linear regression. Results: The average scores of the motive to choose a major, career values, satisfaction with the major, and immersion in the major were 3.15, 3.91, 3.56, and 3.45, respectively. There were significant correlations between all four variables (p<0.05). Career values and satisfaction with the major positively influenced a student's immersion in that major; the explanatory power of the model was 77% (p<0.01). Conclusion: The department should offer education on career values to further increase the immersion of dental technician students within their chosen major.

  • To investigate the potential role of transforming growth factor (TGF)-${\beta}1$ in liver fibrosis during Echinococcus granulosus infection, 96 BALB/c mice were randomly divided into 2 groups, experimental group infected by intraperitoneal injection with a metacestode suspension and control group given sterile physiological saline. The liver and blood samples were collected at days 2, 8, 30, 90, 180, and 270 post infection (PI), and the expression of TGF-${\beta}1$ mRNA and protein was determined by real-time quantitative RT-PCR and ELISA, respectively. We also evaluated the pathological changes in the liver during the infection using hematoxylin and eosin (H-E) and Masson staining of the liver sections. Pathological analysis of H-E stained infected liver sections revealed liver cell edema, bile duct proliferation, and structural damages of the liver as evidenced by not clearly visible lobular architecture of the infected liver, degeneration of liver cell vacuoles, and infiltration of lymphocytes at late stages of infection. The liver tissue sections from control mice remained normal. Masson staining showed worsening of liver fibrosis at the end stages of the infection. The levels of TGF-${\beta}1$ did not show significant changes at the early stages of infection, but there were significant increases in the levels of TGF-${\beta}1$ at the middle and late stages of infection (P<0.05). RT-PCR results showed that, when compared with the control group, TGF-${\beta}1$ mRNA was low and comparable with that in control mice at the early stages of infection, and that it was significantly increased at day 30 PI and remained at high levels until day 270 PI (P<0.05). The results of this study suggested that increased expression of TGF-${\beta}1$ during E. granulosus infection may play a significant role in liver fibrosis associated with E. granulosus infection.

  • This study is a descriptive research study to confirm the degree and correlation of major satisfaction, self-esteem, and work values of nursing students, and was attempted to provide basic data for nursing students' nursing education. The subjects of this study were 224 nursing students from one university in the c region. Data analysis was analyzed using SPSS 22.0 program with frequency and percentage, mean and standard deviation, t-test and ANOVA, and Pearson's Correlation Coefficients. As a result of this study, there was a statistically significant difference in major satisfaction at the time of major decision(F=4.127, P=.004), self-esteem at the motivation for admission(F=7.384, P<.001), and work value at the motivation for admission(F=5.023, P<.001) and the presence or absence of nurses in the family(F=3.501, P<.001). There was a significant correlation between major satisfaction, self-esteem, and work value of nursing college students. Through the results of this study, it is suggested that it is necessary to develop an education and training program that can improve the major satisfaction, self-esteem, and job value of nursing college students.

  • The relationship between second messenger cGMP and human cytomegalovirus (HCMV) replication was investigated. First, the intracellular level of cGMP ([cGMP]i) in HCMV-infected cells was measured. The [cGMP]i increased at early times after HCMV infection, reached maximum level at 12 hr and returned to basal level at 24 hr after virus infection, while [cGMP]i in mock-infected cells remained relatively unchanged. Increasing [cGMP]i resulted in enhanced transcription of HCMV major immediate early gene. For early gene expression, cGMP had varying effect. Expression of 1.2 kb RNA decreased and 2.2 kb RNA increased with increasing cGMP, while 2.7 kb RNA gene expression was not affected. HCMV early genes are regulated by immediate early gene, and the effect of cGMP on the regulatory effect of major immediate early gene on early genes was investigated. In the absence of cGMP, major immediate early gene repressed 2.7 kb RNA gene expression, while 1.2 kb RNA and 2.2 kb RNA early genes were not significantly affected. In the presence of $1\;{\mu}M$ cGMP, however, major immediate early gene stimulated the expression of three early genes.

  • A high molecular ar weight water-soluble chitosan (WSC) with an average molecular weight of 300 kD and a deacethylation level of over 90% was produced using a simple multi-step-membrane separation process. It is known that WSC prevents obesity induced by a high-fat diet. Consequently, this study investigated whether or not WSC improved the ovarian dysfunction caused by obesity in mice. The mice were fed a high density protein and lipid diet for weeks, followed by the administration of WSC at 480 mg/kg body weight per day for 4 days. Thereafter, the changes in body weight, ovulation rate, in vivo and in vitro fertilization and emboryonic development were measured . WSC markedly reduced the body weight of obese mice fed with a high-fat diet, but not in mice fed with a normal diet. WSC had siginificant effects on the ovulation rate, both the in vivo and in vitro fertilization rates and embryonic development. These results indicate an improvement in the ovarian and oviduct dysfunction caused by obesity, and suggest an adjustment in the internal secretions and metabolic functions.

  • The purpose of this study was to examine the correlation between academic achievement, major selection motivation, work value, and campus life adjustment of healthcare major college students. Data was collected using a structured questionnaire for 495 healthcare major college students at a four-year university located in G city. As a result of the study, Academic achievement was determined with positive correlation by major selection motivation (r=.446, p<.001), work values (r=.255, p<.001), campus life adjustment(r=.391, p<.001), Major selection motivation was positively correlated with work value (r=.354, p<.001) and campus life adjustment (r=.220, p<.001). The work value showed a positive correlation with the campus life adjustment(r=.193, p<.001). It is necessary to develop a career education program that reinforces college students' major selection motivation and their work values, and a student guidance program that improves their adaptation to college life.

  • KHPC-002 $[(trans-l-diaminocyclohexane-bis-l,2(diphenylphosphinoethane)platinum)\;{\cdot}2NO_3]$ and $KHPC-006[(cis-diaminocyclohexane-bis-1,2(diphenylphosphinoethane)platinum)\;{\cdot}2NO_3]$ were synthesized as candidates for third platinum antitumor agent. Before their pharmacokinetic study, we optimized the analytical condition with HPLC and identified the major metabolites in the rat plasma. HPLC analysis by $C_{18}$ reverse-phase column showed that standard peak of both compounds appeared rapidly at around 1 minutes, whereas metabolites of KHPC-002 and KHPC-006 which were extracted from plasma after single I.V. administration in rats or incubation for 24 hr at $37^{\circ}C$ showed retention time of $10{\sim}11$ minutes. These metabolites were identified as the major compound by Matrix Associated Laser Deposition/Ionization (MALDI), which only lose the 2 molecules of $NO_3$. Based on these results, we suggest that the major metabolites of KHPC-002 and KHPC-006 were [trans-l-diamino-cyclohexane-bis-l,2(diphenylphosphinoethane)platinum] and [cis-diaminocyclohexane-bis-l.2(diphenylphosphinoethane)platinum], respectively.
