This study was performed to evaluate relationship between health behaviors of local residents and stomach cancer incidence. Case-control study was carried out on 91 cases matched for age and sex with 91 controls in a general hospital in Seoul. It was surveyed using questionnaires and interview from December 20, 2008 to January 30, 2009. Major findings are as follows. First, significant negative association was observed in recreational activity ; OR for active group was 0.23, 0.41 relative to the inactive group. Secondly alcohol consumption was a significant risk factor; relative to non-drinker for drinker of more than 30 years(OR=5.17 95% Cl=1.78-19.95). Thirdly, Eating broiled food showed a positive significant association with risk for stomach cancer(OR=3.79 95% Cl=1.61-9.84) for consumption of three times more per week. As a result of multiple logistic regression analysis, income, BMI 10 years ago, recreational activity, alcohol consumption, eating broiled and salt food were associated with stomach cancer. In conclusion, the correlation of stomach cancer incidence can be found in recreational activity, alcohol consumption, eating broiled and salt food, income, and BMI 10 years ago.

The purpose of this study is to investigate the relationship between suicidal attitude and suicidal ideation of college students and also to provide the fundamental data in order to strengthen both the standard and the recommendation of media coverage in Korea. A total of 249 college students over the age of 18 years in B city and G do were enrolled for this study. The data were collected between June 9 and July 7 of 2014 and analyzed by using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression with SPSS 21.0. The mean score of a message of suicidal motivation reports 2 was $51.06{\pm}10.55$, which was the highest. The score of suicidal ideation was $10.41{\pm}12.88$. There were sign&ificant differences in suicidal thought with respect to school system, family income, pocket money, time of physical activity, smoking, and smart-phone usage in university students. It was shown that suicidal thoughts were significantly correlated with message of simple suicidal reports 1(r=.303, p<.001), message of suicidal motivation reports 2(r=.251, p<.001), and message of suicidal mourning man reports 3(r=.225, p<.001). As the suicidal attitude have a close association with reports of suicide, it is necessary that studies on a variety of factors influencing suicidal thoughts of students be repeated.

This research is a descriptive study that aimed to identify the health knowledge and optimistic bias related to stroke of middle-aged adults and the effect these had on their health-promoting lifestyle. The research was conducted from July 15 to August 15, 2015. The research subjects were 191 adults aged between 40 to 60 years. A structured questionnaire was used and self-administered for data collection. The PASW Statistics 21.0 and AMOS 21.0 programs were used for data analysis, and analysis of variance, correlation analysis, and structural equation modeling analysis were conducted. It was found that the middle-aged adults recognized smoking and hypertension as higher risk factors for stroke than diabetes, and there was a slight optimistic bias for stroke. Health knowledge about stroke had correlations with optimistic bias (r = -.143, p = .048) and health-promoting lifestyle (r = .268, p = < .001), while optimistic bias had correlations with interpersonal relationships and stress (r = .177, p = .014) in health-promoting lifestyle. In addition, health-promoting lifestyle affected health knowledge more than optimistic bias. In conclusion, it was found that the active information acquisition, health knowledge, and optimistic bias of middle-aged adults toward stroke were important factors pertaining to a stroke-related health-promoting lifestyle. Therefore, an education program to improve the health-promoting lifestyle related to stroke in middle-aged adults should be considered as a way to enhance stroke-related health knowledge and reduce optimistic bias.

This study examined the relationship between social support, social participation and physical functioning among older adults in community senior centers. The subjects of this study were 194 persons aged 60 years or older who participated in the senior center in K province and D city, from June 16 to June 30, 2016. The collected data were analyzed using descriptive statistics, T-test, one way ANOVA, Pearson correlation analysis, multiple regression analysis, and structural model analysis using IBM SPSS Statistics 23.0 and IBM AMOS 21.0. The result showed that the social support and physical functioning of the elderly in the community were above normal, and social participation was somewhat low. Interestingly, an analysis of the physical functioning between social support, social participation and depression revealed significant correlations. The factors affecting the physical health were 23.4% of the respondents who had a significant influence on social support and leisure activities. In addition, the result of structural model analysis showed that social support had a significant influence on the social participation, depression and physical functioning. Therefore, the results suggests that the development of educational programs and an age-friendly environment should be actively provided to older adults in the community by strengthening the physical function through social support for active ageing.

The purpose of this study was to investigate the relationship between the fasting blood sugar and serum lipid levels (TC, TG, HDL-C, LDL-C) and obesity indices (BMI, body fat rates, waist circumference, waist to hip ratio). The study sample consists of 1,473 manufacturing workers aged from 30 to 59 years, who underwent a health check-up at a university hospital during the period from Jan. to Dec. 2015. A data analysis was conducted to classify the subjects into the normal and abnormal groups according to their fasting blood sugar levels depending on the average values of the serum lipids and obesity indices. Multiple regression analyzes adjusted for sex and age were conducted for the factors affecting the fasting blood sugar level. As a result, the Serum TC, TG, LDL-C, BMI and waist circumference were found to be significantly higher in the abnormal fasting blood sugar level group than in the normal one, but the HDL-C was significantly lower in the abnormal group than in the normal one The fasting blood sugar level had a significant positive correlation with the TC, TG, LDL-C, BMI and waist circumference. The TC, TG, BMI and body fat were the significant factors affecting the fasting blood sugar. The above results suggest that the fasting blood sugar and serum lipid levels (TC, TG, HDL-C, LDL-C), obesity indices (BMI, body fat rates, waist circumference, waist to hip ratio) of manufacturing workers are significantly associated with each other.
Serum levels of antioxidant vitamins and lipids were determined along with anthropometric measurements in 174 healthy male subjects with mean age of 50.3$\pm$6.8 years from Taegu area in Korea. Body mass index (BMI) and waist/hip(W/H) ratio of the subjects were 23.18$\pm$2.46 and 0.88$\pm$0.04, respectively and their systolic and distolic blood pressures were 127.8$\pm$15.5 and 83.9$\pm$10.8mmHg. Twenty one percent of the subject had BMI over 25. Average seum levels of total cholesterol, LDL- and HDL-cholesterol and triglyceride were 187.7$\pm$34.9, 117.6$\pm$33.5, 41.1$\pm$9.0 and 140.7$\pm$83.6mg/dl, respectively. Sixteen percent of the subject had LDL-chole-sterol over 130mg/dl. Serum level of lipid peroxide measured as thiobarbituric acid reactive substances(TBARS) of the subject was 2.01$\pm$0.77 MDA nmoles/ml and those of $\alpha$-tocopherol, retinol. ascorbic acid and sum of $\alpha$- and $\beta$-carotene were 9.59$\pm$3.11$\mu\textrm{g}$/ml, 1.15$\pm$ 0.38$\mu\textrm{g}$/ml, 10.5$\pm$3.8$\mu\textrm{g}$/ml and 64.6$\pm$43.$\mu\textrm{g}$/dl, respectively. About 14% of the sujects had low vitamin E status of less than 7.0$\mu\textrm{g}$/ml,. while 6% had low vitamin C status of less than 4.0$\mu\textrm{g}$/ml, Serum vitamin E showed positive correlations with total cholesterol and LDL-cholesterol and triglyceride, but no correlation with TBARS. Fatty acids of serum total lipid were composed of 42.9% as saturnted. 19.3% as monounsaturated and 36.7% polyunsaturated fatty acids(PUFA). N-6 and n-3 PUFA were 27.7% and 8.3% of total fatty acids. N-6/n-3 PUFA ratios were negatively correlated both with serum total cholesterol and TBARS.
The objective was to evaluate the factors influencing on the growth of children aged 3 - 6 years by mini dietary assessment and anthropometric indices in 556 children and by analyzing mineral contents of hair from 273 children by inductively coupled plasma mass spectrometry (ICP-MS). The mean concentration of zinc (Zn) in hair was 68.9 $\pm$ 31.1 ppm and the zinc level of 91 % children was less than 60% of the reference value of 180 ppm. The mean content of lead (Pb) in hair was 1.76 $\pm$ 1.20 ppm, but only 67% of 273 children was within the reference value of 2 ppm and the lead level of 33% of children was 2 - 4 times higher than the reference value. The level of Zn was negatively correlated with Pb content (r = -0.305, p 〈 0.01). Hair Zn content, regardless of age, was significantly positively correlated with height (r = 0.214) and body weight (r = 0.159). The height of 95.3% children was belonged to the normal range of 90 - 109.9% of standard value and the body weight of 49.8% children was in the range of 90 - 109.9% of standard value. However, 8.1 % children was overweighted (110 - 119.9% of standard) and 9.4% children was obese (120 - 149.9% of standard) and 0.9% children was severe obese (〉 150%) which resulted in total 10.3% obese. Contrary to our expectation, 32.8% children was underweight (70 - 89.9% of standard) and 36% of the underweight children showed the low content of zinc (10 - 49 ppm) in hair. There was no significant correlation between dietary intake of Zn and hair Zn content. Hair Zn content was low even though children consumed greater than 75% of their requirement for zinc. Regardless of dietary intake of Zn, hair Zn level was rather negatively correlated to the content of Pb in hair. 38.8% children had an unbalanced diet which resulted in lower intake of calorie, Ca, Zn, vitamin B$_2$ compared with those consuming variety of foods. Therefore, it would be needed that new approach for nutrition education to improve eating habit having the unbalanced diet in preschool children. It might be also suggested to develop new food products to complement the nutrients of Zn, Ca, Fe as snacks or dietary supplement for Korean preschool children.
Objective : To evaluate the role of stereotactic LINAC radiosurgery in treatment of meningiomas, the authors retrospectively analyzed the result of radiosurgery in our institute. Method: During last ten years, twenty patients underwent stereotactic LINAC radiosurgery(LINAC SRS) for meningiomas. The mean age of the patients was 51 years(22-78 years). The most common tumor location for radiosurgery was parasagittal, sphenoid wing and tentorial area. With regards to indications of radiosurgery for meningiomas, LINAC radiosurgery was done for primary treatment in six patients, for postoperative residual tumors in eleven patients, for postoperative regrowth in three patients. Mean tumor volume was $5.14cm^3$($0.28-15.1cm^3$), mean field diameter was 2.01cm(1.2-3cm). The mean marginal dose was 20.55Gy(13-30Gy). The follow-up evaluation was done annually with radiologic findings and clinical status. The mean follow-up period was 46.8(24-120) months. Result : In the radiologic response, the tumor volume was reduced in five(25%) of twenty patients, fourteen showed arrested growth(70%), but one patient showed increased growth(5%). In the clinical response, nine patients improved clinically(45%), ten patients was stable(50%) and one patient worsened during follow-up period. With regards to correlation with radiologic and clinical response, in nineteen patients who showed radiologic response to radiosurgery(decreased and arrested growth after radiosurgery), nine patients(47.4%) improved and ten patients (52.6%) showed no change, one patient(5%) had symptomatic radiation necrosis at four years after SRS, which needed craniotomy. Conclusion : The overall control rate of meningiomas with LINAC radiosurgery was 95% in radiologic follow up and 95% clinically. The radiation complication rate was 5%. These results indicate that LINAC radiosurgery can be considered as safe and effective method for meningiomas.

Objective : Laminoplasty is an effective surgical method for treating cervical degenerative disease. However, postoperative complications such as kyphosis, restriction of neck motion, and instability are often reported. Despite sufficient preoperative lordosis, this procedure often aggravates the lordotic curve of the cervical spine and straightens cervical alignment. Hence, it is important to examine preoperative risk factors associated with postoperative kyphotic alignment changes. Our study aimed to investigate preoperative radiologic parameters associated with kyphotic deformity post laminoplasty. Methods : We retrospectively reviewed the medical records of 49 patients who underwent open door laminoplasty for cervical spondylotic myelopathy (CSM) or ossification of the posterior longitudinal ligament (OPLL) at Pusan National University Yangsan Hospital between January 2011 and December 2015. Inclusion criteria were as follows : 1) preoperative diagnosis of OPLL or CSM, 2) no previous history of cervical spinal surgery, cervical trauma, tumor, or infection, 3) minimum of one-year follow-up post laminoplasty with proper radiologic examinations performed in outpatient clinics, and 4) cases showing C7 and T1 vertebral body in the preoperative cervical sagittal plane. The radiologic parameters examined included C2-C7 Cobb angles, T1 slope, C2-C7 sagittal vertical axis (SVA), range of motion (ROM) from C2-C7, segmental instability, and T2 signal change observed on magnetic resonance imaging (MRI). Clinical factors examined included preoperative modified Japanese Orthopedic Association scores, disease classification, duration of symptoms, and the range of operation levels. Results : Mean preoperative sagittal alignment was $13.01^{\circ}$ lordotic; $6.94^{\circ}$ lordotic postoperatively. Percentage of postoperative kyphosis was 80%. Patients were subdivided into two groups according to postoperative Cobb angle change; a control group (n=22) and kyphotic group (n=27). The kyphotic group consisted of patients with more than $5^{\circ}$ kyphotic angle change postoperatively. There were no differences in age, sex, C2-C7 Cobb angle, T1 slope, C2-C7 SVA, ROM from C2-C7, segmental instability, or T2 signal change. Multiple regression analysis revealed T1 slope had a strong relationship with postoperative cervical kyphosis. Likewise, correlation analysis revealed there was a statistical significance between T1 slope and postoperative Cobb angle change (p=0.035), and that there was a statistically significant relationship between T1 slope and C2-C7 SVA (p=0.001). Patients with higher preoperative T1 slope demonstrated loss of lordotic curvature postoperatively. Conclusion : Laminoplasty has a high probability of aggravating sagittal balance of the cervical spine. T1 slope is a good predictor of postoperative kyphotic changes of the cervical spine. Similarly, T1 slope is strongly correlated with C2-C7 SVA.

This study was conducted to investigate dietary factors, bone status, and bone loss in postmenopausal women in rural areas. A total of 189 women participated in the follow-up study after two years. Radius, Tibia, and Phalanx SOS (Speed of Sound) was measured on two occasions 2 years apart by ultra-sonic-metry, and % body fat was measured by bioelectrical impedance analysis at the baseline and after 2years. Dietary intake data were collected 4 times at different season by 24-hour recall method, and then calculated as average. Bone density of radius decreased by 4.2% during the two year period. When the subjects were divided into three groups, by bone decline level during two years, the lowest bone loss group had higher potassium and vegetable intake than other groups. Age and calcium intakes showed significant correlation with bone decline rate at tibia. In multiple regressions, the baseline SOS, vitamin A, vegetables and eggs intakes were found to be significant factors for tibia bone decline. In conclusion, dietary factors, such as higher vegetable intake, seem to affect the changes in bone mineral density in more favorable way. Therefore, efforts are needed to enhance the access to nutritional care for rural elderly postmenopausal women.
