The purpose of this study was to identify factors associated with falls among older adults. This cross-sectional study used the data of 10,272 older adults who participating in the Korean Elderly survey, including demographic and health related characteristics. The data were analyzed with complex samples in SPSS ver. 23.0. The results of multiple logistic regression analysis showed that age (OR=1.262, 95%CI 1.111-1.433), education (OR=0.846, 95%CI 0.764-0.937), subjective health status (OR=1.172, 95% CI 1.041-1.320; OR=1.422, 95%CI 1.289-1.570), number of chronic illness (OR=1.438, 95%CI 1.050-1.968), number of medications (OR=0.798, 95%CI 0.659-0.967), muscle strength of low extremities (OR=1.260, 95%CI 1.101-1.441), and fear of falling (OR=3.576, 95%CI 3.166-4.039; OR=14.236, 95%CI 12.637-16.038)were significantly associated with fall accidents in the elderly. Thus, it is necessary to develop fall prevention program to reduce fear of falling and improve health status in the elderly.

The purpose of this study was to provide basic data to promote health in middle-aged Koreans (40-59 years old) by understanding health behaviors that affect high-density lipoprotein (HDL) cholesterol level among various health behaviors. In a national health and nutrition survey, raw data combined on a total of 7,406 persons, IV-3 (2009), V-1 (2010), V-2 (2011), V-3 (2012), and VI-1 (2013), were selected as the final analysis subjects. HDL cholesterol was divided into two groups: less than 40 mg/dl and more than 40 mg/dl. The results of multiple logistic regression analysis were as follows: OR=3.916 for males, OR=3.439 for normal than low weight, OR=7.336 for obesity than low weight, OR=1.629 for alcohol consumption, OR=1.498 for smokers, OR=1.426 for don't practice moderate physical activity, OR=1.264 for no walking exercise, OR=1.510 for carbohydrates normal intake than low intake, OR 1.787 for carbohydrates over intake than low intake when HDL cholesterol increased from 40 mg/dl to less than 40 mg/dl. Korean middle-aged high-density lipoprotein (HDL) cholesterol levels should be increased to maintain proper health through aerobic exercise, smoking cessation, proper drinking habits, obesity relief, healthy eating out, and healthy food choices. This requires continuous publicity and education within the community, and a social environment should be built that enables health behavior to be practiced in daily life.

The Article 17 (1) of the Medical Service Act states that no one but medical doctor, dentist or herb doctor shall prepare medical certificate, post-mortem examination, certificate or prescription. Though medical certificate, post-mortem examination or certificate is a private document issued by doctor personally, it is accepted as reliable as public document. Therefore, for medical certificate, post-mortem examination or certificate, unlike other private document to guarantee authenticipy of the content, the Article 233 of the Criminal Act states the Crime of Issuance of Falsified Medical Certificates. In other words, the Criminal Act Article 233 states that If a medical or herb doctor, dentist or midwife prepares false medical certificate, post-mortem examination or certificate life or death, one shall be punished by imprisonment or imprisonment without prison labor for not more than three years, suspension of qualifications for not more than seven years, or a fine not exceeding thirtht million won. The subject of the Crime of Issuance of Falsified Medical Certificates is only a medical or herb doctor, dentist or midwife and the eligibility requirements are specified in the Medical Service Act. Medical certificate is the medical document to be issued by medical doctor to certify the health status and show the Jugdement about the result of the diagnosis, Post-mortem examination is the document to be listed by medical doctor to confirm medically about human body or dead body, and Certificate life or death is a kind of medical certificate to verify the fact of birth or death, the cause of death, such as Birth Certificate, Certificate of Stillbirth or Certificate of Dead Fetus. To constitute the crime of Issuance of Falsified Medical Certificates, it is necessary for the contents of the certificate to be substantially contrary to the truth, as well as it is needed the subjective perception that the contents of the certificate are false. The Supreme Court Decision 2004DO3360 Delivered on March 23, 2006 declared that although the Defendant did not MRI scan, etc. for precise observation about the disability status of Mr Park, it was difficult to believe that the contents of the Disability Certificate of this case were contrary to the objective truth or the defendant had perception that the contents of the certificate were false. I don't agree with the Supreme Court Decision, because the Supreme Court confirmed the decision by the court below despite the Supreme Court should have made the court below retry the reason why the Defendant did not MRI scan, etc. for precise observation about the disability status of Mr Park.

Purpose: This study was found the risk factors of cataract by gender in elder and older Korean adults. Methods: We investigated the data for 5,024 (men 2,163 people, women 2,861 people) people, aged 40-95 years, from the Korean National Health and Nutrition Examination Survey. We divided into two groups (group 1: 40-64 years, group 2: 65-94 years). We divided into two groups (group 1: 40-64 years, group 2: 65-94 years). Cataract was decided in case of at least one eye with lens opacity. We presented significant odds ratio (OR) increase of cataract according to the obesity and socioeconomic information including house income and education level after adjusting for diabetes, hypertension, high triglyceride, outside active, smoking and drinking habits in two groups with distinction of sex. Results: House income (or education) was strongly related to the prevalence of agerelated cataract in all groups. In models adjusting for all other related factors, cataract patients with lower income and education had a higher prevalence of cataract (group1: OR, 1.84[1.17-2.91], OR, 3.00[1.90-4.74], group 2: OR, 3.47[2.53-4.74], OR, 7.44[5.41-10.23] for men. In comparison, for women, cataract patients with lower income, lower education and obesity had a higher prevalence of cataract (group1: OR, 1.72[1.14-2.60], OR, 4.48[2.72-7.38], OR, 1.40[1.10-1.82], group 2: OR, 2.32[1.70-3.16], OR, 29.99[20.31-44.28], OR, 1.27[1.04-1.54]). Conclusions: Factors of low socioeconomic status were associated with age-related cataract in Korean. Obesity-cataract association was stronger in women.

The present study sought to assess the health-related behavior affecting hypertension in the Korean elderly. A data set comprising 1,404 subjects aged ≥65 from the Korea National Health and Nutrition Examination Survey VIII-1 (2019) was analyzed. In men, the incidence of hypertension was associated with age (odds ratio [OR], 1.056; P=0.004), absence of a family history of chronic diseases (OR, 0.662; P=0.024), underweight status (OR, 0.142; P<0.001), normal weight status (OR, 0.390; P<0.001), and non-drinkers (OR, 0.552; P=0.001). In women, the incidence of hypertension was associated with age (OR, 1.091; P<0.001), absence of a family history of chronic diseases (OR, 0.424; P<0.001), normal weight status (OR, 0.532; P<0.001), and poor subjective health level (OR, 1.640; P=0.018). In conclusion, the factors affecting hypertension in men were age, obesity, family history of chronic diseases, and drinking. In women, the factors affecting hypertension were age, obesity, family history of chronic diseases, and subjective health level. Therefore, it is proposed to make efforts to establish gender-appropriate health promotion and intervention programs and health policies to reduce the incidence of hypertension in the elderly.

Objectives: The purpose of this study is to determine the relationship between electronic cigarette use and mental health factors such as stress, suicidal thinking, and generalized anxiety disorder among Korean adolescents. Methods: Based on the 19^th (2023) Youth Health Behavior Survey, cross-analysis(Rao-Scott χ2 test) and complex design logistic regression analysis were conducted to identify e-cigarette use and mental health factors. Results: Lifetime use experience with electronic cigarettes (OR:1.218) and current use of electronic cigarettes (OR:1.266) for male adolescents and lifetime use experience of electronic cigarettes(OR:1.587 ) for female adolescents were influential factors on stress. Lifetime experience with e-cigarettes (OR:1.866) and current use of e-cigarettes (OR:1.651) for male adolescents and lifetime experience with e-cigarettes (OR:2.375) and current use of e-cigarettes (OR:1.841) for female adolescents were influential factors on suicidal thinking. Lifetime experience with e-cigarettes (OR:1.307) among male adolescents and lifetime experience with e-cigarettes (OR:1.616) among female adolescents were influencing factors for generalized anxiety disorder. Conclusion: Because there is a significant relationship between adolescent e-cigarette use and mental health, e-cigarette prevention education is needed early in adolescence.

The objective of this study was to optimize the selection of sperm sources, optimal culture systems and vitrification method depends on sperm sources. The oocytes were inseminated with either KPN 105, 114, 191, SNU 101, 102, 103 or epididymis and then embryos inseminated were cultured in oviductal cell co-culture or HECM-6 as defined me dium. The blastocysts produced were pooled according to sperm sources as KPN, SNU or epididymis and then vitrified by OPP vitrification method. The results obtained were as follows: 1. The cleavage(86.2 or 84.7%) and development rates to blastocyst (30.6 or 32.0%) were not significantly different between oviductal cell co-culture or HECM-6 culture systems(P<0.05). 2. To determine the optimal sperm sources for using IVF in this system, cleavage rates in KPN 191 and SNU 101 (74.2, 55.8%) were significantly lower rather than those in KPN 105, 114, SNU 102, 103 or epididymis (86.7, 85.1, 89.8, 85.5 or 81.2%), but development rates to blastocyst in KPN 114, SNU 103 or epididymis sperm (30.0, 33.0 or 28.6%) were significantly higher rater than those in KPN 105, 191, SNU 101, 102(21.4, 15.4, 14.9 or 25.4%), respectively (P<0.05). 3. The blastocysts produced were pooled according to sperm sources as KPN, SNU or epididymis and then vitrified by OPP vitrification method. The survival rates were not significantly different among sperm sources (89.6%: 43/48 ; 90.1%: 46/51 ; 83.3% : 20/24). These results obtained indicate that the defined medium, HECM-6, could be use to produce of IVP bovine embryos. Since the frozen semen must be required to maintain of unvariation data in IVP embryo production system, KPN 114 and SNU 103 produced in our laboratory were useful for this purpose. The blastocysts produced by different sperm sources as KPN, SNU or epididymis were vitrified by OPP vitrification method and survived very high rates. The OPP vitrification method could be susceptibility to use of IVP bovine blastocyst embryos.

Objective : To poll oriental medical doctors on their opinions about the necessity of standard medical charts and of detailed items in their development. Currently, oriental medical institutions use their own medical charts, but a standard medical chart is necessary for medical information sharing. Methods : Report by 912 of the 10,490 oriental medical doctors surveyed on their general aspects, actual conditions, and requirements. Results : The oriental medical doctors surveyed who worked in oriental medicine clinics, oriental medicine hospitals, and public health centers said medical examination programs should consist of chief complaints (said by 814 respondents or 89.25%), history (792 or 86.84%), ordinal symptoms (753 or 82.57%), diet (727 or 79.71%), emotions and overstrain (654 or 71.71%), side effects and allergies (622 or 68.20%), improvement of symptoms (605 or 66.34%), a questionnaire on particular diseases (558 or 61.18%), social aspects (523 or 57.35%), a physical examination (520 or 57.02%), a questionnaire on syndrome differentiation (514 or 56.36%), diagnosis using medical devices and laboratory tests (471 or 51.64%), and Sasang constitution (357 or 39.14%). Ninety-one percent of the respondents said they intended to use a standard chart, and 82.19% agreed to share patient information with medical institutions. Conclusions : Over 90 percent of the oriental medical doctors surveyed said they need a standard medical examination program. Oriental medical examination items that correspond with the opinions of the oriental medical doctors surveyed and of experts will thus be developed, and the draft chart will be distributed to oriental medical institutions with the developed medical forms and electronic medical chart.
