Objectives : This study investigated the level of sexuality knowledge and gender sensitivity and factors influencing on them among Korean high school and college students. Methods : 129 questionnaires from high school and college students with consent forms, collected from July to December of 2022, were analyzed. After identification of participants' gender, age, major, their report of the practicality of sex education, and their experience of violence or sexual assaults, participants' level of sexuality knowledge and gender sensitivity were compared. Results : Females showed higher gender sensitivity, regardless of age and group (p=0.004). The early adulthood group (≥19 years old) showed higher sexuality knowledge and gender sensitivity, compared to those adolescents (<19 years old). Among college students, those who majored in health science were identified with higher sexuality knowledge and gender sensitivity, compared to non-health science major students(p<0.001; p=0.005). Conclusions : This study revealed the significant differences in sexuality knowledge and gender sensitivity according to sex, age, and majors in adolescents and early adults. Therefore, it seems to be necessary to consider the differences in sexuality knowledge and gender sensitivity among age, sex, and majors when establishing public policy or legislation for sex crimes, including digital sex crimes.

Purpose: This study aimed to investigate the perceptions of the dietary guidelines for Koreans (DGK) among Korean adults based on sociodemographic and lifestyle factors. Methods: A total of 514 Korean adults aged 19-64 years completed a self-administered online questionnaire assessing their perceptions of DGK, sociodemographic and lifestyle factors, and subjective assessments regarding the importance of 11 nutrients and 16 food groups. The differences in the perceptions of DGK according to the characteristics of the participants were analyzed using t-tests or ANOVA. Additionally, the differences in the subjective assessments of nutrients and food groups according to the perceptions of DGK were examined using t-tests. Results: The awareness of DGK was significantly higher among participants aged 50-64 years, living in single-person households, who were physically active, with a lower frequency of eating out, and with a higher interest in dietary information (p < 0.05 for all). The understanding of DGK was significantly higher among participants aged 19-29 years, females, individuals who were under or normal weight, non-smokers, those who self-evaluated their diet as healthy, and those with a high interest in dietary information (p < 0.05 for all). Additionally, the applicability of DGK was significantly higher among participants aged 50-64 years, who were physically active, who self-evaluated their diet as healthy, and who had a high interest in dietary information (p < 0.05 for all). Participants with a higher perception of DGK tended to attribute greater importance to most nutrients and food groups compared to those with a lower perception level. However, processed meat and foods, beverages, and alcoholic drinks consistently received lower importance ratings compared to other nutrients and food groups, regardless of the perception level. Conclusion: This research suggests that the perceptions of DGK among Korean adults may vary depending on sociodemographic and lifestyle factors. Consequently, there is a need to customize and diversify the methods for providing dietary guidelines.

Objectives: This study was conducted to examine the association of serum Vitamin D with insulin resistance and ${\beta}-cell$ function in Korean health checkup examinees. Methods: This study subjects were 374 healthy adults (199 males, 175 females) over the age of 20, who visited a general hospital medical center located in Haenam-gun, Jeollanam-do. To find the association of Vitamin D with HOMA-IR and $HOMA-{\beta}$, the used statistical analysis were ANOVA and ANCOVA. Results: Of the study subjects, the level of serum Vitamin D defined by deficient group, insufficient group and sufficient group was 38.5%, 48.1% and 13.4%, respectively. According to the level of serum Vitamin D, the mean values of HOMA-IR were $1.92{\pm}1.08$ in sufficient group, $1.99{\pm}1.04$ in the insufficient group and $2.91{\pm}1.05$ in deficient group and there were statistically significant different(p<0.001). The mean values of $HOMA-{\beta}$ were $84.69{\pm}1.07$ in sufficient group, $78.41{\pm}1.04$ in the insufficient group and $80.48{\pm}1.04$ in deficient group, and there were not significant. As a result of ANCOVA, adjusted mean of HOMA-IR were statistically significant different (p<0.001), but those of $HOMA-{\beta}$ were not statistically significant according to the level of serum Vitamin D. Conclusion: The insufficient level of serum Vitamin D was relatively high in healthy adults who live in rural area, and it was found that HOMA-IR significantly increased when Vitamin D was deficient. To prevent insulin resistance or diabetes, it is necessary to provide sufficient information related to sufficient production of Vitamin D such as Vitamin D supplement, sun exposure, food intake and etc.

Purpose : Acute measles encephalitis(ME) is characterized by an abrupt onset of fever and obtundation, frequently accompanied by seizures and multifocal neurological signs. The aim of this study was to clarify the clinical manifestation, progression and the brain SPECT patterns in patients with acute ME. Methods : This study included 11 children with acute ME admitted to Chonbuk National University Hospital. Ten patients received a first dose of measles vaccine, one patient did not receive a first dose, and no patients received a second dose. ME was diagnosed based on characteristic clinical pictures, measles antibodies by ELISA and abnormal CSF findings. Brain MRI and brain SPECT were performed in 11 patients with acute ME. Results : There were four males and seven females whose ages at onset ranged between 18 months and 14 years(mean : 10.5 years). The main clinical neurologic pictures were loss of consciousness( 10) and seizure(five). The titer of IgG and IgM antimeasles antibodies in serum were positive in 10 patients. In CSF, nine patients had IgG antibodies and one patient had IgM antibodies. The concentration of protein(mean : $124{\pm}60mg/dL$) and WBC counts(mean : $158{\pm}157/{\mu}L$) in CSF were elevated in all patients. In electroencephalographic examination, nine patients showed increased slow waves. Seven of 11 patients(63.6%) revealed high signal intensity on the brain MRI. In contrast, all patients showed hypoperfusion in brain SPECT examination. According to brain SPECT, the perfusion deficits were frequently observed in the frontal lobe(nine), temporal (nine), parietal(eight) and thalamus(eight). Conclusion : Brain SPECT is more sensitive than MRI for the evaluation of brain damage in early stages of acute ME.

The purpose of this study was to evaluate the amount and interrelationship of the soft tissue of nose and maxillary changes and to identify the nasal morphologic features that indicate susceptibility to nasal deflection in such a manner that they would be useful in presurgical prediction of nasal changes after maxillary advancement surgery in skeletal Class III malocclusion. The sample consisted of 25 adult patients (13 males and 12 females) who had severe anteroposterior skeletal discrepancy. The patients had received presurgical orthodontic treatment. They underwent a Le Fort I advancement osteotomy, rigid internal fixation, alar cinch suture and V-Y advancement lip closure. The presurgical and postsurgical lateral cephalograms and lateral and frontal facial photographs were evaluated. The computerized statistical analysis was carried out. Soft tissue of nose change to h point change ratios were calculated by regression equations. The results were as follows 1. The correlation of maxillary hard tissue horizontal changes and nasal soft tissue vortical changes were high and the ${\beta}_0$ for soft tissue to ADV were 0.228 at ANt, 0.257 at SNt. 2. The correlation of maxillary hard tissue and nasal soft tissue horizontal changes were high and the ${\beta}_0$ for soft tissue to ADV were 0.484 at ANt, 0.431 at SNt, 0.806 at Sn. 3. The correlation of maxillary hard tissue horizontal changes and width changes of ala of nose were high and the ${\beta}_0$ lot alar base width ratio to ADV were 0.002. 4. The DRI, Prominence of nose, Pre-Op CA is not a quantitative measure that can be used clinically to improve the predictability of vertical and horizontal nasal tip deflection. In this study, increases in nasal tip projection and anterosuperior rotation occur when there is an anterior vector of maxillary movement. These nasal changes were Quantitatively correlated to magnitude of maxillary(A point) movement.

The purpose of this research is to do exploratory analysis on the relationships between demographic characteristics of entrepreneurial candidates and their developmental level of entrepreneurial traits as well as the choice of business field. We analyzed gender, age, and educational level of the entrepreneurial candidates and their developmental level of entrepreneurial traits such as achievement tendencies, degree of awareness, planning skills, sincerity, interpersonal relationship, and problem-solving skills. Industry fields were classified into 4 types: restaurants, retail, services, internet business. Descriptive statistical analyses, logistic regressions, and variance analyses were performed about the sample data gathered from 1,441 persons since the year 2002 to 2014. Males and highly educated above university preferred service industry than restaurant, retail, and internet business. Females preferred internet business, retail, and restaurants than service industry field. The young persons under 20 showed higher probability to choose internet business. The college level and high school graduates preferred retail and restaurants than service industry. The developmental level of entrepreneurial traits were higher in male and highly educated. By this study, we could find the divide between groups with high and low probabilities of failure: restaurants and retail field showed higher failure probability than service industry in the business fields of self-employed. Furthermore, we could identify that entrepreneurial traits also had been developed differently depending on the groups. It is necessary to refrain from entering into the fields with high failure probabilities as well as to provide supporting policies to build the systems and environment to reduce the cases to begin new business without special knowledges and know-hows. The competency development training should be provided in the early stage of start-ups considering their entrepreneurial traits and aptitudes. Not only the assessment of the entrepreneurial traits but also professional counseling from initial stage are necessary.

Purpose : The aim of this study is to identify where and how adolescents acquire cigarettes and how many were asked for identification while purchasing cigarettes. Methods : This study was conducted in 2003; participants were 2,200 students in middle and high schools, aged from 13 to 18 years old(males 1,098; females 1,102) in Ansan, Korea. The questionnaire assured them of anonymity, and self-administered in school. The data was analyzed with chisquare test for trends. Results : The prevalence of smoking was about 20 percent among respondents, was higher in males than in females, and in older students than in younger students(P<0.001). The most frequent source of cigarettes was purchased from a store(36.3 percent). About 29.2 percent of the students borrowed from friends or family members. By sex, the main sources of cigarettes were purchase from a store and borrowing. Younger students were borrowed more cigarettes; older students purchased more cigarettes from stores. Only 48.8 percent were asked for proof of age during their purchase. Of those asked for proof of age, about 73.3 percent answered that this made it difficult to buy cigarettes(P<0.001), and they thought that it was more difficult when asked for a photo ID than simply being asked their age(P=0.019). Conclusion : So far, there has been no systemic prevention of adolescents' smoking. It is difficult for minors to purchase cigarettes if asked for proof of age, but most minors go to stores to purchase cigarettes. Therefore, prevention efforts should include educating retailers not to sell cigarettes to minors and enforcing existing laws requiring youth to provide proof of age when attempting to buy cigarettes.

An eating behavior research was done with 50 females at a buffet styled restaurant during their lunch time. Of the respondents, 52.0% were professional and 54.0% were graduate school graduates. Of the respondents, 58.0% of the company were friends and 24.0% were relatives. The average time period of eating was $93.0{\pm}23.4$ minutes. The average frequency of taking food was $4.0{\pm}1.1$ and the average frequency of taking food after satiety was $1.4{\pm}0.8$. It is significant that lower frequency of food consumption was directly proportional to the age groups of respondents. The average selected food items were $30.4{\pm}7.1$ out of 175 and the average weight of the consumed food was $995.0{\pm}240.9$ g. The older age group chose a similar number of food items, but the amount of each food item was considerably less than younger. So the younger the age group was, the more they ate. The average food items at one time was $7.1{\pm}2.2$ and the average food weight time was $233.7{\pm}69.7$ g. The percentage of respondents who evaluated themselves as 'ate too much' was 70.0% and those who evaluate themselves 'ate properly' was 14.0%. Most of them were satisfied with the buffet service. The average of number of food items consumed by respondents before cooking was $50.5{\pm}8.9$. The consumption of calories and nutrients was compared with the Korean Daily Recommended Dietary Allowances. The consumed calories were 60.9% of RDAs, protein 104.4%, calcium 77.1%, iron 129.8%, vitamin A 66.5%, thiamin 96.0%, riboflavin 95.7%, niacin126.6% and ascorbic acid 112.3%. This data exceeded 1/3 of the Korean Daily RDAs tremendously and tells us extreme overeating. The energy ratio of carbohydrate: fat: protein was 51.6: 29.9: 18.5. Caloric consumption of animal food was 27.9% and the consumption rate of the other nutrients from animal food was considerably high. But the consumption rate of vitamin A was 90.9% from vegetable groups. Accoding to this study, buffet service gives some advantages. It gives customers an good opportunity to vary their food intake, which enhances eating experiences and can cause an improvemont of food habits. But overeating is a problem. Therefore, we think it is necessary for those women who have influence over their family's food selection, to have nutrition education about a desirable order of eating a meal, food selection, and health problems due to overeating at buffet styled restaurant. There should be some improvement in the management of buffet service. For example, proper temperature, texture, and freshness of the food should be maintained. Prevention of mixed food smells should be considered as well. To lower the price it is desirable to reduce the number of similar items and to use seasonal food as much as possible. A buffet styled restaurant with less food items with cheaper prices is recommended. Various traditional food should be developed for the menu items. We expect buffet services to be sutable to maintain good health and to be popular to any eater.

This study aimed to investigate the general characteristics of patients with acute cerebral infarction, the characteristics of its treatment and its correlation with stroke rating scale and to analyze the factors that affect patient's quality of life. The subject of this study was 576 patients who survived more than a year after they were diagnosed with cerebral infarction that occurred within 7 days and discharged from a study center. Their quality of life was investigated through phone interview. The average age of subjects was $65.8{\pm}12.4$ years old and male subjects took up 62% among all subjects. The mean of quality of life showed $0.77{\pm}0.29$. There was statistically significant difference in factors such as gender, age, hypertension, atrial fibrillation, stroke history and smoking. The result of multiple regression analysis showed the quality of life was lower in females than in males and it was significantly low in older subjects or those with stroke history. Also high stroke scale was related to significantly low quality of life. As such, hospitalized patients due to stroke should receive appropriate intervention during the hospitalization and after their discharge and the development of program is required to prevent relapse.
