This study compared the health behaviors, health related clinical characteristics between individuals with Glycated Hemoglobin A1C≧6.5% and < 6.5% in 30~59yr. Factors that were associated with A1C were identified by sex, health behaviors, health literacy. This study was an observational study with a cross-sectional design based on data from 2019~2021 Korea National Health and Nutrition Examination Survey. Multiple logistic regression analysis was employed to compute the odds ratios of health behaviors to identify the risk factors for Glycated Hemoglobin. The prevalence of A1C≧6.5% among the total was 79.4%(weighted %, n=348). In the A1C≧6.5%, 71.8% were men. In univariate logistic regression for A1C≧6.5%, sex, duration with diabetes, and body mass index(BMI) were influencing factors. In multiple logistic regression by sex, the factors associated with A1C≧6.5 in women were as follows: education(OR 4.5; 95% CI:1.1, 18.5), duration with diabetes(OR 2.9; 95% CI 1.1, 7.9). Strategies should be targeted to improve health behaviors and clinical characteristics for those in their sex, women in low education level, duration with diabetes. Moreover, healthcare providers should understand the barriers to health behaviors and health literacy to effectively deliver healthcare service.

Hermaphroditism occurs rarely in human and animal populations. Previously, in Korea, The hermaphrodite dog in American Cocker Spaniel dogs have been reported in six cases. However, in this case, we found a hermaphrodite dog in Korean native Jindo dog. The characteristics were its enlarged os clitoris that was shown a reddish fingerlike structure protruding from the vulva. The dog was diagnosed as hermaphroditism with ovotestes. To our knowledge, this report is the first case of hermaphroditism in Korean native dog.

배아의 성별 판별을 위해 할구를 biopsy하여 핵상에서 정밀 분석을 하였다. 이 실험에서는 8-에서 16-세포기 배아의 할구를 배아 성결정의 대표물로 사용하여 IVF소 배아를 분석 평가하였다. 55개의 배아를 PCT후 biopsy하여 분석하였다. PCR에 의한 성판별에서 biopsy한 single blastomere와 blastocyst의 성판별의 일치하는 비율은 80%인 것으로 나타났다. IVF 수정란을 염색체 상태에서 평가하기 위해 8- 16- 세포기의 할구를 Karyotyping 하였다. 할구의 Karyotyping을 위해 metaphase 상태에서 vinblastine sulfate에 계속적으로 노출시켜 metaphse Ⅱ 상태를 유도하였다. (중략)

현 시점에서의 인구의 성별/연령별 구성은 과거의 출산, 사망에 의한 인구진행과정(demographic process)의 잔류효과라고 볼 수 있다. 한편 현재의 인구의 성별/연령별 구성은 장래의 인구증가에 잠재적인 영향력을 미치게 된다. 예를 들면 인구의 대부분이 45세 이상으로 구성되어 있다면 출산률은 낮고 사망률은 높아서 인구증가는 더디다. 즉 인구의 연령별 구성은 인구증가를 좌우하는 하나의 동적인 요인으로 볼 수 있다. 연령구성이 한 결과인 동시에 하나의 요인이기도 하다는, 이러한 이중적인 성격은 서로 얽히고 복잡한 것이다. 이 논문에서는 둘째 관점, 즉 연령구성을 하나의 동적요인으로 보고, 그것이 인구증가에 미치는 잠재력(potentail) 또는 관성(momentum)에 관해서 고찰하고 최근(1970, 1975)의 한국 센서스 결과에 대해서 이를 정량적으로 계측하고자 한다.

The study was conducted to predict usage attitudes and behaviors by combining usage motivation and sensitivity, gender, and age in aviation-related social media. Specifically, the purpose of this study was to examine the effects of social media information acceptance, motivation and sensitivity on gender acceptance by gender and age. To this end, we collected data in an even distribution to prevent gender and age bias among adults aged 20 or older online from April 19 to May 3, 2018. As a result, the lower the female and age in the gender and age had a positive effect on the acceptance of social media information. Motivation for use has a positive effect on information acceptance and sensitivity has a negative effect on information acceptance. Through this, it was found that user class such as gender and age, motivation to use, and sensitivity affect information acceptance. In addition, the negative aspects of the sensitivity factor can be identified, and it is expected to be used as basic data in aviation-related social media marketing strategies.

The purpose of this study was to examine Korean consumers' awareness of Cultured Meat(CM) and influencing factors by gender. On-line survey was conducted from June 9 till June 15, 2021. Analyses of 1,008 respondents whose ages were 20 or older resulted in three points. First, Korean consumers' awareness of CM were lower than the medium in the scale of 1-5, and men reported higher level of awareness than women. Second, the awareness of CM differed by socio-demographic characteristics of participants. The younger, the higher educated, and the students showed higher level of awareness of CM. Third, influencing factors on the awareness of CM differed by gender. In total, gender, age, job, health concern, environmental concern, perceptions of Traditional Meat(TM), and early adopter tendency were significantly associated with the awareness of CM. Among men, age, job, health concern, and early adopter tendency were significant influencing factors on the awareness of CM, where as age, education, health concern, environmental concern, perceptions of TM, and early adopter tendency were so among women. The study results may be used as basic data for developing policies for CM research and consumers.

인간과 기계가 효과적인 상호작용을 하기 위해서는 컴퓨터 시스템이 인간의 행동을 인식할 수 있어야 한다. 본 연구에서는 인공 신경망을 사용하여 컴퓨터 시스템이 인간의 움직임을 관찰한 후 행위자의 성별을 인식하도록 하는 시스템을 구현하였다. 두 가지 감정상태(보통상태, 화난 상태) 하에서 일어난 인간의 세 가지 동작(문 두드리기, 손 흔들기, 물건 들어올리기)을 대상으로 하여 인간 동작 데이터를 통해 만들어진 학습 데이터를 통해 98.0%의 인식률을 보일 때까지 학습시키고 나서, 이전에 사용하지 않았던 새로운 데이터에 대해 얼마나 설별을 잘 구별해 내는지 실험하였다. 동작이 일어나는 동안 행위자의 몸 여섯 군데에서 속도 데이터를 얻어내서 신경망의 입력값으로 사용하였다. 그 결과 최저 62.3%이상 최고 94.3%까지 인간 성별을 구분해 낼 수 있었고 이는 같은 데이터에 대해서 사람을 통해 실험한 것보다 훨씬 나은 것이다.

Objectives: Narcolepsy is characterized by excessive sleepiness, cataplexy, sleep paralysis and hypnagogic hallucination. As there have been few researches on narcolepsy symptomatology in adolescents, we examined gender differences and prevalence of narcolepsy tetrad among students attending high school. Methods: Total 20,407 subjects, ages 14-19 years filled out Ullanlinna Narcolepsy Scale (UNS). Subjects whose UNS scores were equal to or more than 14 were interviewed by telephone using semi-structured questionnaire. Variables included questions to evaluate tetrad of narcolepsy. Results: UNS scores were higher in female than male ($11.1{\pm}5.2$ vs. $9.6{\pm}4.5$, p<0.001). Subjects scoring the UNS equal to or more than 14 were 4,535 (22.2% of all the participants), more frequently observed in female than in male (p<0.001). Excessive daytime sleepiness, cataplexy-like symptoms, sleep paralysis and hypnagogic hallucination in subjects of UNS ${\geq}14$ were significantly higher in female subjects than male ones. However, no significant gender difference was observed in the frequencies of severe sleep attack and cataplexy-like symptoms. Sleep paralysis was most frequently reported during sleep. There was significant correlation between sleep paralysis and hypnagogic hallucination (r=0.235, p<0.01). Conclusions: Our findings were that female adolescents complained more frequently narcolepsy symptoms than male subjects. Female adolescents might be more sensitive than male ones to physical complaints such as sleepiness or muscle weakness.

Gender differences have been studied by using spectral features such as median frequency (MDF) respectively. MDF is the most commonly used as a feature to describe muscle conduction velocity. The aim of this paper is to detect gender differences from surface EMG signals during isotonic contractions of the bicep Brachii. Eight volunteers participated in surface EMG recordings placed on the biceps brachii and each recording experiment continued until their exhaustion. We used feature values and regressive slopes and compared the feature changes from the onset to the endurance time to find gender differences. The result of experiments shows that the regressive slope of these features is valid to measure gender differences.

In the current study, the effects of living-alone older adults' social participation on their depressive symptoms were assessed. Data of 924 older adults from the Aging Research Panel Survey were analyzed. The results show that the effects of older adults' social participation on depressive symptoms vary depending on the types of social participation and gender. Men attending school or hometown alumni meetings and clan gatherings showed fewer depressive symptoms; women participating in informal social gatherings or organizations for leisure, culture, and sports had fewer depressive symptoms. The results suggest that living-alone older adults' gender and dimensions of social participation should be considered when designing programs and services to reduce their depressive symptoms.
