Purpose: This study was conducted to identify factors associated with high-risk drinking in Korean men. Methods: This study was a secondary analysis using data from the Korea National Health and Nutrition Examination Survey (KNHANES VIII-2), 2020. Data were downloaded from the KNHANES website. The subjects of this study were 1,653 alcohol-drinking men between 19 and 64 years of age. Data were analyzed using the Rao-Scott chi-square test and complex sample logistic regression statistics. Results: The high-risk drinking rate among alcohol-drinking men was 27.1%. High-risk drinking was more common in men who smoked (odds ratio [OR] = 2.11, p < .001), men with a middle school education or lower (OR = 1.91, p = .016), men who lived with a spouse (OR = 1.61, p = .025), men who slept less than 6 hours on weekends (OR = 1.51, p = .016), and men who perceived stress (OR = 1.30, p = .044), while it was lower in men who were underweight (OR = 0.19, p = .006). Conclusion: To reduce the rate of high-risk drinking, it is necessary to provide an intervention that considers factors associated with high-risk drinking among men. In particular, smoking was the most important factor associated with high-risk drinking, implying that the integrated management of drinking and smoking is necessary to reduce high-risk drinking.

In the twenty first century, people experience a lot of stresses by psychological, social and environmental impetus. If the stress is excessive, it can become a problem and finally lead to diseases. Foot bath makes the body warm starting with the feet, controls the blood circulations and autonomic nervous systems. This study aims at examining the effects of stress and fatigue of senior students preparing for college entrance examination by foot bath with the aroma essential oil and the fermentation extracts. The experimental period was from March 30 to April 18, 2009. The study objects were 21 senior students of C Girls' High School in Cheonan. They were divided into 3 groups and treated 20 times. The first group was a foot bath group with Artemisia Herbal fermentation extracts. The second group was a foot bath group with the blending aroma essential oil of grapefruit, cypress and cedarwood. The third group was not treated. In the case of difference of physical and psychological stress, there was a reduction of 18.43 and 16.71 for the fermented extract group and 10.71 and 9.43 for the aroma group, while a reduction of 0.43 and 0.29 for the control group, respectively. This shows that foot baths using fermented extracts and aroma had lower physical stress compared to the control group (p<.01). For the difference of fatigue, there was a reduction of 19.14 for the fermented extract group, 11.57 for the aroma group and 0.07 for the control group, showing that foot baths accompanied by fermented extracts and aroma used in this study having lower fatigue compared to the control group (p<.01). The fermented extract group (M=55.71) had the highest level of satisfaction after foot baths, followed by the aroma group (M=49.14) and the control group (M=33.29). Duncan's post hoc test showed that there was a statistically considerable difference between the tests groups and control groups (p<.01). Through the results of this study, it was found that foot baths using bathing supplements were very effective for reducing stress and fatigue.

In order to see the development of Nursing related research activities in Korea over the last three decades, abstracts of almost all of the Master and Ph.D theses that appeared from 1961 up to August 1991 were collected. The number of theses was 2354, from which an index of key words has been constructed. Key words were defined as those terms in each thesis title that convey major objectives of the given thesis study and the important nursing concepts dealt with in the thesis. Although all the key words were picked from the thesis title only, full use was made of the abstracts in deciding the principal objectives and essential contents of the thesis studies and their important concepts as well. In total, 539 kinds of key words were identified from the 2354 titles, and the identified words were all found to be in the International Nursing Index. On an average each title has two key words. Which key words were most frequently used, how they have changed with time, what kind of concept is preferably dealt with by each graduate school, and the concepts to which a given key word is likely to be connected were examined. The results are summerized below : 1) For each decade the theses numbers were as follows : 54(2.3%) from the 60’s, 413(17.5%) from the 70’s, 1523(64.7%) from the 80’s, and 364(15.5%) from the 90’s. Master’s thesis contributed 96% (2252) of the papers and Ph. D’s theses filled the remaining 4%(102). 2) A total of 539 key words were used, averaging about 2 for each thesis. The most frequently used key words were ‘Nurse’, ‘Anxiety’, ‘Knowledge / Attitude /Practice’, ‘Stress /Stressor’, ‘Attitude’, ‘Job-Satisfaction’, ‘Mental Disorder’, ‘Operation’, ‘Elderly’, ‘Nursing Role’. 3) Each decades key words can be classified as : the 60’s : ‘Nursing Education’, ‘Pulmonary Tuberculosis’, ‘Mother-Child Health’, ‘Growth & Development’, ‘Public Facilities’, ‘Mental Disorder’ : the 70’s : ‘Nurse’, ‘Family Planning’, ‘Attitude’ / ‘Knowledge, Attitude / Practice’, ‘Curriculum in Nursing Education’, ‘Clinical Practice in Nursing’, ‘Analysis of the Work of the Nurse’, ‘Health Education of School’, : the 80’s : ‘Nurse’, ‘Anxiety’, ‘Stress /Stressor’, ‘Operation’, ‘Nursing Role’, ‘Job Satisfaction’ : the 90’s : ‘Nurse’, ‘Elderly’, ‘Family-Support’, ‘Stress /Stressor’, ‘Home Care’. Key word ‘Nurse’ appears continuously and most frequently through the years, which indicates that there has been active study of the characteristics of nurses and related fields. The concept ‘Anxiety’ has been studied steadly from the 80’s and it shows that interest in health and disease are increasing Which comes as a result of society changing to an industrial and informational community. 4) Looking into each graduate school’s study area key words ‘Anxiety’, ‘Nurse’, ‘Mental Disorder’, ‘Stress /Stressor’, ‘Operation’, ‘Attitude’, ‘Hemo-dialysis’, were studied in the regular graduate school : ‘Family Planning /Contraception’, ‘Knowledge / Attitude /Practice’, ‘Physical Health-State /Physical Health Examination’, ‘Nurse’, ‘Using Clinical Facilities’, ‘Health Education of School’, were studied in the Graduate School of Public Health’ ; ‘Nurse’, ‘Anxiety’, ‘Stress / Stressor’, ‘Job-Satisfaction’, ‘Clinical Practice Education’, ‘Nursing Education’, were studied in the Graduate School of Education : ‘Nurse’, ‘Job Satisfaction’, ‘Nursing Role’, ‘Administration - Employment /Employment Management’, ‘Leadership’, ‘Personnel Profile’, ‘Nursing Manpower / Changing Working Place’, were studied in the Graduate School of Public Administration. 5) The Connection between key words were : ‘Nurse Job Satisfaction’, ‘Stress / Stressor ⇔ Coping / Ajustment’, ‘Nurse ⇔ Nursing Role’, ‘Anxiety ⇔ Giving Information’, ‘Nurse ⇔ Stress / Stressor’, ‘Anxiety ⇔ Operation’, ‘Nurse ⇔ Burnout’, ‘Knowledge, Attitude, Practice ⇔ Family Planning’, ‘Nurse Administration ⇔ Employment’, ‘Anxiety Muscle ⇔ Relaxation Technic’, ‘Anxiety ⇔ Mental Disorder’. From the above it can be noted that many nursing concepts were handled in the thesis titles. But there were more than enough papers on the characteristics of the nurse. It is suggested that in depth research be made on ‘Nursing Accidents’, t-‘Ethics’, ‘Nurse - Patient Interactions’, ‘Spritual Care’, ‘Dying’, ‘Hospice’, ‘Resident Helper’ and that there should be in depth research relating to the physical and mental development of youth and in particular physical concepts like ‘Drug - Abuse’, ‘Child -Abuse and Teaching’.

Purpose: We evaluated the efficacy of ultrasonographic examination of the medial collateral ligament injury in elbow joints in the high school male weight lifting athletes. Materials and Methods: The study group (group I) included 15 male weight lifting athletes (average age: 16.8) and the control group (group II) was demographically matched 9 male with no symptoms on their elbow. Both elbow joint was evaluated through physical examination, plain radiograph, valgus stress view and ultrasonography. Results: On plain radiograph, there was no significant differences (3.6 mm, 2.7 mm; p>0.05) for the medial articular distances between both groups. The valgus stress view revealed the significant increase in group I (right, avr. 5.86 mm and 3.52 mm, p<0.01, left, avr. 5.33 mm and 3.64 mm, p<0.01). On ultrasonography, medial joint space was increased in group I (right, avr. 4.66 mm and 3.29 mm, p<0.01, left elbow 4.28 mm and 3.38 mm, p<0.01). The lateral shifting of proximal ulna also increased in group I (right, avr. 0.73 mm and 1.43 mm, p<0.01, left, avr. 0.96 mm and 1.53 mm, p<0.05). The angular deformity were more prevalent in group I. Conclusion: The medial joint space widening and angular deformity was prevalent in male weight lifting athletes. the ultrasonographic examination was useful in evaluating the degree and incidence of the medial collateral ligament injuries.

The structural framework design uses high-strength bolts and welding in column splices. However, for the column under high compression, the number of the required high-strength bolts can be excessive and the increase of welding results in difficulty of quality inspection, the transformation of the structural steels, and the increase of erection time. According to the AISC criteria, when columns have bearing plates, or they are finished to bear at splices, there shall be sufficient connections to hold all parts securely in place. The Korean standard sets the maximum 25% of the load as criteria. Using direct contact makes it possible to transfer all compressive force through it. The objective of this study is to examine the generally applied stress path mechanism of welded or bolted columns and to verify the bending moment and compression transfer mechanism of the column splice according to metal touch precision. For this study,22 specimens of various geometric shapes were constructed according to the change in the variables for each column splice type, which includes the splice method, gap width, gap axis, presence or absence of splice material, and connector type. The results show that the application of each splice can be improved through the examination of the stress path mechanism upon metal contact. Moreover, the revision of the relative local code on direct contact needs to be reviewed properly for the economics and efficiency of the splices.

The purpose of this study was to examine the effect of anxiety and depression on health-related QOL(Quality of Life) of middle aged women and to test hypothetical model of QOL. This study is a pathway analysis study using 1692 middle aged women whose age range is between 40 and 64. This study was performed as secondary analysis using the data from the 2015 Korean Social Psychological Anxiety Examination Survey. Data were analyzed using descriptive statistics, correlation analysis and pathway analysis. As a result, Stress, social support, aged preparation, self-esteem, anxiety, depression and QOL showed significant correlation. Anxiety was directly affected by stress(.21, p=.009) and social support(-.05, p=.046). Depression was directly affected by stress(.28, p=.016), social support(-.10, p=.008) and self-esteem(-.38, p=.039). Both anxiety(-.16, pp=.009) and depression(-.17, p=.011) had effect on QOL but depression was mediated by anxiety in affecting to QOL. Anxiety and depression of middle aged women affect to QOL and QOL is affected by depression via anxiety. It suggests that it needs to provide nursing intervention for mental health such as anxiety and depression for QOL of middle aged women.

One aspect of undesirable outcomes in orthodontic treatment includes excessive resorption of dental roots with mechanotherapy. The aim of this study is to demonstrate whether diseases affecting the immune system adversely are prevalent in orthodontic patients who manifest excessive resorption of dental roots with orthodontic tooth movement. The records of 51 orthodontic patients (25 males and 26 females, $16.1{\pm}3.3$ yr old) and 51 pair-matched controls ($1.5.4{\pm}4.1$ yr old) were analyzed retrospectively. The pretreatment questionnaires and the treatment records disclosed that the incidence of asthma, allergy, and signs indicative of psychological stress, was significantly higher in the root resorption cohort. The immune system is either altered or adversely affected in all these conditions. Since the progenitors of osteoclasts and odontoclasts are derived from mononucleated cells of monocyte and macrophage lineage, which are prominent cellular members of the immune system, the study leaded to the conclusion that excessive root resorption may occur in orthodontic patients who are psychologically stressed, or who have asthma and allergy, or any other conditions that may adversely affect and modify the immune system, and a careful examination and interpretation of a patient's medical history may be beneficial to both patient and practioner.

We have carried out a nondestructive close examination for the purpose of the structural safety diagnosis of the Dabo Pagoda of Bulkuk temple located in Kyungju, Kyungbuk Korea. For estimating the mechanical properties of each rock block of the pagoda, ultrasonic measurements were conducted at 641 points of 255 blocks. The P-wave velocity ranges from 584m/sec through 5,169m/sec, and averages 2,901m/sec Based on this result, the uniaxial compressive strength was estimated to be $93{\sim}1,943kg/cm^2\;with\;396kg/cm^2$ of average, and the index of weathering is $0.07{\sim}0.88$ with 0.43 of average, which means the moderate degree of weathering. The comparison of the rock strength of each block with the overburden acting on the block reveals that the rock blocks related to the structure of the pagoda are relatively sound for uniform stress, but it is highly possible for a concentrated stress to lead to a partial failure. We suggest a monitoring of cracks due to the concentrated stress. The parapets of 1st and 2nd floors composed of small rock pieces are severely weathered. However, this is not directly related to the structural safety of the pagoda.

Effluent of aquaculture industry has caused a growing concern regarding its environmental impact. We assessed the use of flounder farming sewage as supplement of diet, to minimize the impact of aquaculture on the environment or also establish the technique for the recycling of effluent sediment derived from land-based seawater fish farm. In order to investigate the effects of a fermented aquaculture waste on biochemical responses of olive flounder (Paralichthys olivaceus), fermented products of aquaculture wastes were used as test compounds that cause hepatic and renal stress through the induction of oxidative stress in liver and kidney. Hepatosomatic index (HSI), glutathione content and glutathione dependent enzyme were not significantly different and no correlation was found within the different types of fermentation condition or supplement concentration, except for significant increases in 50% fermentation group and 50% concentration group in case of glutathione peroxidase activity and HSI value, respectively. These results showed addition of fermented aquaculture sewage may be an economic artificial sources of diet for fish aquaculture practices without affecting the function and safety in view of biochemical examination.

As is well known that N-nitroso-N-methylurethane (NNNMU) causes acute lung injury (ALI) in experimental animals. And ALI caused by NNNMU is very similar to ARDS in human being in its pathology and progress. In its context, we investigated the pathogenetic mechanism of ARDS associated with oxidative stress by neutrophils in Sprague-Dawley rat model of NNNMU-induced ALI. NNNMU had increased lung weight/body weight ratio (L/B ratio), lung myeloperoxidase (MPO) activity, protein content and number of neutrophils in bronchoalveolar fluid (BALF) compared with those of control rat (p<0.001, respectively). In contrast, the amount of pulmonary surfactant in BALF was decreased by NNNMU (p<0.001). Morphologically, light microscopic examination denoted pathological findings such as formation of hyaline membrane, infiltration of neutrophils and perivascular cuffing in the lungs of NNNMU-treated rats. In addition, ultrastructural changes such as the necrosis of endothelial cells, swelling and vacuolization of lamellar bodies of alveolar type II cells, and the degeneration of pulmonary surfactant were identified after treatment of NNNMU. Very interestingly, cerium chloride electron microscopic cytochemistry showed that NNNMU had increased the production of cerrous-peroxide granules in the lung, which signified the increased production of hydrogen peroxide in the lung. Collectively, we conclude that NNNMU causes acute lung leak by the mechanism of neutrophilic oxidative stress of the lung.
