This study utilized data from 1,068 women aged 40-59, drawn from the 8th Korea National Health and Nutrition Examination Survey (KNHANES) conducted in 2020, to investigate factors impacting subjective health perception and health-related quality of life. Methodologically, STATA 15.0 was employed for complex sample mean and standard deviation calculations, complex sample weighted percentages, complex sample t-tests, and multiple regression analyses. Common factors influencing both subjective health and health-related quality of life included education level, household size, depression, and stress. Age, binge drinking, and physical activity were identified as factors influencing subjective health perception. Insurance type, employment status, and sleep disorders emerged as factors impacting health-related quality of life. Recognizing middle age as a crucial transitional phase into old age, the development of health policy programs aimed at enhancing subjective health and health-related quality of life during this period is deemed essential.

The aging and growth of Spisula sachalinensis from Ingu over the period from December 1981 through November 1982 were studied. The rings on the shell were used as the character for age determination. The ring where the translucent zone shifts to the opaque one was regarded as an annulus. The time of its formation was estimated by monthly variations of marginal growth rate in the shell. It was formed once a year over the period from August through September. The shell length at the formation of the annulus was estimated by taking the mean shell length corresponding to each of the annual ring. From analysis of mean shell length at the formation of the annulus, von Bertalanffy's growth equation was estimated as follows; $l_t=126.38(1-e^{-0.262(t-0.656)})\;W_t=485.85(1-e^{-0.262(t-0.656)})^3$ Back-calculated shell lengths estimated from this equation was quite consistent with actual shell lengths.

Objectives: This study aimed to investigate factors influencing suicidal ideation among Korean adults. Methods: Cross-sectional data from the fifth Korea National Health and Nutritional Examination Survey conducted in 2012 were analyzed in this study. The subjects were categorized into three groups by subjects' age(defined as young adults(20-39), middle-aged adults(40-59), and the elderly(60 or more). Data were analyzed by frequency, Chi-square test and multiple logistic regression using SPSS 18.0. Results: The factors influencing suicidal ideation were different among three age groups. The influencing factors were (1) gender, marital status, household income, perceived stress and depression in the young adult group, (2) household income, perceived health status, perceived stress and depression in the middle-aged group, (3) gender, regular physical activity, smoking, perceived health status, perceived stress and depression in the elderly group. Conclusions: The health education considering the characteristics of each age group should be developed and applied to prevent adults' suicidal ideation because the factors influencing suicidal ideation were revealed differently between the age groups.

The Potosinian geological basement in central Mexico is comprised of the Upper Paleozoic metamorphic rocks, which crop out on the Sierra de Catorce nucleus located in the northeastern part of the state. The sedimentary sequence that covers unconformably the Paelozoic basement is represented by an Upper Triassic marine sedimentary sequence, correlating to the Zacatecas Formation and the Upper Triassic continental Huizachal Formation red beds, which in turn are covered either by La Joja Formation Jurassic red beds or by Upper Jurassic marine sediments. This sequence is overlain by the conformable Cretaceous calcareous marine sedimentary rocks in all the state of San Luis Potosi. The Cenozoic sequence unconformably covers some of the aforementioned rocks and is represented by undifferentiated volcanic rocks as well as by marine clastic rocks. The existing intrusive igneous rocks are felsic to intermediate composition, and they intrude the metamorphic basement and sedimentary rocks. Conglomerates with evaporitic sediments were deposited during the Pleistocene. The Quaternary sequence includes basalt flows, piedmont deposits, alluvium, and occasionally evaporites and caliche layers. In the state of San Luis Potosi, a great diversity of mineral deposit types is known as both metallic and nonmetallic. The host rocks of these deposits vary from one another including formations that represent from Paleozoic up to Tertiary. The mineralization age corresponds approximately to Tertiary (75%), and is mainly epigenetic. Conclusively, the data on geology and mineralization in San Luis Potosi, Mexico are helpful to predict a hidden ore body and select promising mineralized zone(s) when the domestic company makes inroads in the mining sector of Mexico.

Purpose: The purpose of the study was to identify women's osteoporosis knowledge, concerns about osteoporosis factors, and health behavior as well as to examine the relationship between these variables. Methods: The participants were 394 women in the Jeonbuk area. The data were analyzed using a t-test, ANOVA, Duncan test, and hierarchical regression analysis with SPSS v. 24.0. Results: The score for osteoporosis knowledge was 6.21 points out of a possible 12, the score for concern about osteoporosis factors was 26.50 points out of a possible 40. The score for the health behavior was 57.26 points out of a possible 85. The knowledge showed significant differences according age (p < 0.01), income (p < 0.05), education level (p < 0.01), drinking milk in childhood (p < 0.05), health interest (p < 0.05), and osteoporosis information (p < 0.01). The concern showed significant differences according to age (p < 0.001), income (p < 0.05), health interest (p < 0.001), osteoporosis information (p < 0.001), family history of osteoporosis (p < 0.05), and calcium medications (p < 0.001). The health behavior showed significant differences according to age (p < 0.001), income (p < 0.01), drinking milk in childhood (p < 0.05), health interest (p < 0.001), osteoporosis information (p < 0.01), and calcium medications (p < 0.01). Regression analysis showed that the concern about osteoporosis factors was the most influential variable on health behavior, followed by health interest of the subjects, age, and the osteoporosis knowledge. Conclusion: Therefore, it is necessary to consider educational programs on increasing interest in osteoporosis according to the age and health for improving the health behavior to prevent osteoporosis.

This study was undertaken to identify factors that influence high-risk drinking among women. Seventh National Health and Nutrition Survey data were used, and 3,453 women aged 19 or older were studied. Subjects were divided into general and high-risk drinking groups according to high-risk drinking rate indicators, and these groups were compared to identify demographic and sociological characteristics, differences in health-related characteristics, and factors associated with high-risk drinking. The data analysis was performed using IBM SPSS 25.0. The analysis showed 8.8% of the cohort were high-risk drinkers, and that rates of high-risk drinking were higher among women in their 20s to 30s, smokers, and those with experience of depression. In particular, smoking, and depression were associated with a 4.5 [(95% confidence interval (CI)=2.804-7.372, p<0.001)] and 7.0-fold [(95% CI=2.918-16.855, p<0.001)] increases in rates of high-risk drinking. In addition, the risk of high-risk drinking was high among 15- to 19-year-olds, which indicates an urgent need to develop and implement drinking education programs for women in adolescence and early adulthood. We expect the results of this study to be used to create health policies and health promotion programs aimed at reducing the high-risk drinking rate among women.

This study was conducted to examine the therapeutic compliance and its related factors in rural women with osteoporosis. A questionnaire survey was performed from April to May in 2000 for 140 osteoporotic patients who were diagnosed from April to June in 1999 through community health program. The study employed the health belief model for predicting and explaining sick role behavior. The analysis techniques employed included contingency table analysis and path analysis using LISREL. The major results of this study were as follows: Of the subjects, 12.1% were continuously complaint, 53.6% were intermittently compliant, and 34.3% were non- compliant to calcium supplement therapy. As the result of path analysis, the therapeutic compliance was significantly higher(${\mid}T{\mid}$ >2.0) as patients had higher perceived severity of disease, lower perceived barriers of treatment, and when patients thought their disease status as severe. As the patients had higher educational level, more experience of mass media contact or health education about osteoporosis, and when family had more concern for patient treatment, they had higher perceived susceptibility of complication(bone fracture)${\mid}T{\mid}$ >2.0). The patients had higher perceived severity(${\mid}T{\mid}$ >2.0) as they had more educational level, more advice for treatment from their doctors, and when family had more concern for their treatment. As the patients had more advice for treatment from their doctors and when family had more concern for their treatment, they had higher perceived benefit of treatment and lower perceived barriers to treatment(${\mid}T{\mid}$ >2.0). In order to improve the therapeutic compliance in rural osteoporotic women, it would be necessary that the patient should recognize their disease severity properly. And the perceived barriers should be removed through supportive environments for osteoporosis treatment such as doctor 's more advice and family 's more concern for treatment. In addition, effective and continuous management system for osteoporotic patients should be established.

Purpose : The purpose was to assess the result of arthroscopic management of the septic arthritis on the knee in compromised patients. Materials and Methods : Fourteen patients with septic knee were analyzed. The mean age was 55 years and the mean follow-up period was 14.6 months. Underlying diseases included 4 cases of diabetes, and history of direct acupuncture in 4 cases. Clinical stage of septic arthritis was judged by $G\ddot{a}chter's$ classification, which was determined by arthroscopic findings. After arthroscopic irrigation and debridement, we observed the results of laboratory data and improvement of clinical findings. Results : Causative organism was identified in 7 cases and no organism was detected in the remaining 7 cases. Stage I was 1, stage II 8, stage III 4, and stage IV 1, respectively. Eleven of 14 cases were improved by one stage operation. Two cases of stage III were recurred and additional arthroscopic management was done. In 1 case of stage IV, symptom was not improved and needed arthrotomy. The result was unsatisfactory in patients with stage III and IV. Serum erythrocyte sedimentation rate and C-reactive protein were normalized after 29.3 and 20.8 days following the operation, respectively. Clinical symptoms disappeared average 2 days following the operation. Conclusion : Arthroscopic management of acute septic arthritis of the knee would be an effective and satisfactory treatment modality in that its postoperative pain and complications are minimal, and it can be done with ease repeatedly.

Purpose: This study calculated the prevalence of cataract in Korean and examined corrected eyesight with different types of opacification of crystalline lens. Methods: Using the data of the national health and nutrition examination survey (NHANES), population-based and cross-sectional research were designed in this study. After dividing total 4,977 persons into different groups by age, from 40 to 95 and by sex, the prevalence of cataract with different types of opacification was investigated. The average age of the total subjects was $58.28{\pm}12.07$, and the number of men and women were 2,142(43.0%) and 2,835(57.0%), repectively. Eyesight was calculated when it was less than 0.63. Results: Among total 4,977 subjects, 40.6% (men 17.5%, women 23.1%) had cataract. Different prevalence rates were found with different types of cataract; nuclear cataract (56.3%), cortical cataract (23.4%), mixed cataract (16.2%), anterior subcapsular(3.0%), and posterior subcapsular (1.1%) in order. There was no difference among men and women by the types. And those in their 40's showed a higher prevalence of cortical cataract than those in the other age groups. Most of subjects whose corrected eyesight is less than 0.63 had anterior subcapsular cataract. Conclusions: The type of cataract having the highest prevalence was nuclear opacity. Moreover, epidemiologic investigation and prevention policy with different type of lens opacity seems to be required.

In order to investigate the relationship between the menarche and the bone maturity of growing girls, the author interviewed about the date of menarche of 70 girls and assessed their bone maturity by hand-wrist radiographs. The results and conclusion were as iollows ; 1. The mean menarcheal age was $12.04{\pm}0.82$ year. 2. There was significant correlation between the time interval after menarche and the ossification stage. 3. The skeletal maturation level at menarche was stage SMI 7 and SMI 8. 4. There was statistically different among the time intervals after menarche according to the ossification stage. 5. The epiphyseal union of radius began about 2 years after menarche. According to this study, the probability of clinical use can be accepted in some range. In another words, skeletal age can be predicted by just interviewing the date and time interval of menarche without hand-wrist radiograph, also, with this information, the level of maxillofacial growth can be assessed.
