  • Objectives The purpose of this study is to investigate the interest level, perception and attitude of suicide high-risk group toward the media's suicide report, and also to provide the fundamental data in order to strengthen both the standard and the recommendation of media coverage in Korea. Methods We analyzed the data from the 2013 The Korea National Suicide Survey. The study included 1500 participants aged between 19 and 75 years. The participants were selected through the regional multi-layer stratification method using the sampling frame of the 2010 Census. One-on-one face-to-face interviews investigated the interest level, opinions, and attitudes toward suicide reports and collected data on past suicide history and demographic data. The collected data were evaluated using multiple logistic regression analysis. A probability level of p < 0.05 was considered statistically significant. Results The suicide high risk groups with histories of suicidal ideations or attempts showed more interest in suicidal reports [suicidal thought odds ratio (OR) = 1.81, 95% confidence interval (CI) = 1.40-2.34 ; suicidal attempt OR = 3.21, 95% Cl = 1.52-6.78]. However, there was no difference among the groups in thought that suicide reports incite suicide (suicidal thought OR = 1.26, 95% Cl = 0.92-1.73 ; suicidal attempt OR = 0.96, 95% Cl = 0.44-2.09). The suicide high risk groups showed a positive attitude toward suicide reports, but it was not statistically significant (suicidal thought OR = 1.10, 95% Cl = 0.41-2.92 ; suicidal attempt OR = 1.10, 95% Cl = 0.76-1.59). Conclusions We suggest the need of careful attitude of media suicidal reports not to bring about copycat suicides. and also we offer suicide prevention campaign based on media leverage.

  • The aim of this study was to successfully reflect human body changes on the transformation of the virtual body within 3D virtual fitting spaces. For this purpose, existing problems of shape transformation of the virtual body were analyzed and regression equations which provides useful basic data for transformation of the virtual body that can be applied usefully to the 3D virtual fitting system was developed. Necessary data for the analyses were body measurement and 3D scan data of women with average physical form between the ages of 40 through 49. The reason that we used human body changes of the female subjects in their forties was based on the recognition that fundamental female body changes start to occur from age of forty. Body shapes were largely divided into 3 groups according to obesity which was found to be the biggest factor of shape change. Seven factors were extracted based on factor analysis of 47 body measurement categories and regression equations were created to extract specific measurements for each BMI group based on these seven factors. The major contribution of this paper can be summarized as follows. First, the regression equations to extract specific measurements based on the 7 representative variables remediated existing problem of virtual bodies as it increased the number of body shape transformation areas. Second, the regression equations helped to overcome the problem of current failing to reflecting changes in body cross-section shape based on simple girth measurements based on analysis of cross-section distances.

  • We present a new description of envelope-function equation of the superlattice (SL). The SL wave function and corresponding effective-mass equation are formulated in terms of a linear combination of Bloch states of the constituent material with smaller band gap. In this envelope-function formalism, we review the fundamental concept on the motion of a wave packet in the SL structure subjected to steady and uniform electric fields F. The review confirms that the average of SL crystal momentums K = ($k_x,k_y,q$), where ($K_x,k_y$) are bulk inplane wave vectors and q SL wave vector, included in a wave packet satisfies the equation of motion = $_0+Ft/h$; and that the velocity and acceleration theorems provide the same type of group velocity and definition of the effective mass tensor, respectively, as in the Bulk. Finally, Schlosser and Marcus's method for the band theory of metals has been by Altarelli to include the interface-matching condition in the variational calculation for the SL structure in the multi-band envelope-function approximation. We re-examine this procedure more thoroughly and present variational equations in both general and reduced forms for SLs, which agrees in form with the proposed envelope-function formalism. As an illustration of the application of the present work and also for a brief investigation of effects of band-parameter difference on the subband energy structure, we calculate by the proposed variational method energies of non-strained $GaAs/Al_{0.32}Ga_{0.68}As$ and strained $In_{0.63}Ga_{0.37}As/In_{0.73}Ga_{0.27}As_{0.58}P_{0.42}SLs$ with well/barrier widths of $60{\AA}/500{\AA}$ and 30${\AA}/30{\AA}$, respectively.

  • Purpose: This study aimed to examine changes of empathy levels of nursing student in two different curricula structures, one called "traditional" and the other called "integrated" curricula. The study was a longitudinal design to follow a cohort of nursing students to examine the magnitude of changes in empathy in their education years. Methods: The study was conducted in a public school of nursing giving a baccalaureate degree, which had a fundamental change in their curricula. In all, 81 students from the traditional curricula and 66 students from the integrated curricula completed the study, and data from a total of 147 students were analyzed between 2003 and 2008. The Empathic Communication Skills Scale and the Empathic Tendency Scale were given to the students in the beginning of their freshman year and at the end of the fourth year just before graduation. Results: Although both of the curricula were seemed effective at improving empathic skills of students, especially the scores of students who completed the integrated curricula were higher than the scores of the other group attending the traditional curricula (p<.05). However, the empathic tendency scores of students in both curricula decreased at the end of fourth year. Conclusion: Although undergraduate nursing curricula either traditional or integrated improved empathic skills, it seemed that integrated curricula were more effective than traditional curricula in increasing empathic skills. The more hours and more experiential methods contributed to improved empathy. The decrease in empathic tendency requires further attention of educators and nurse managers.

  • The purpose of this study is to suggest fundamental information about wearing method and production of brassiere, which is suitable for physiological hygiene and efficient action for elderly women. The subject is 418 elderly women aged 50∼69 years old. Data is processed by a computer(SAS) and is analyzed by using frequency, percentage, x²-test. The main results of this study are as follows. 1. Elderly women'weight and breast size are higher thant their younger counterparts'in their 20's, but the older and poorer women with more children have smaller weight and breast. Most of the elderly women feel that their breasts are drooped or falling apart. I fact, those elderly women who gave birth to more children have more drooped and wider breasts. The major type of elderly women'breast is the 'drooped breast' featured more by those elderly women who have more children. 2. Most of the elderly women began to wear the brassiere for the first time in their 20's the older women with more children began to wear the brassiere earlier, while those less educated and poorer began to protect their breasts with brassiere later. Many elderly women wear the brassiere to be protected from dirt, noise or look more neat, but day tend to wear the brassiere not all day around but at certain times, older, less educated and proper women with more children tend to use the brassiere for etiquette and less often. This group of elderly women feel tedious, stage or uncomfortable for the brassiere. 3. Most of the elderly women know about their brassiere size. Such variables as age, education and income are correlated positively with the interest in and consciousness of the brassiere size. All in all, the statistical distribution of elderly women's brassiere size is very wide, while most of them use 90A, 85A and 95A sizes. On the other hand, the most popular size of the under bust circumference is 85∼90cm, while their primary cup size is A.

  • The purpose of this study was to investigate the relationship between Trp64Arg polymorphism in the ${\beta}_3$-adrenergic receptor gene and complex phenotypes such as blood pressure, body compositions and bone parameters in young men about 20 years, and to collect the fundamental data in designing the exercise program. Eighty healthy young men including 41 controls and 39 athletes were recruited, Trp64Arg polymorphism in the ${\beta}_3$-adrenergic receptor gene was genotyped by PCR-RFLP method. By association study, there were no significance in genotype and allele frequencies of Trp64Arg polymorphism in the ${\beta}_3$-adrenergic receptor gene between controls and athletes, respectively (p>0.05). When the relationship between physiological parameters and Trp64Arg polymorphism in the ${\beta}_3$-adrenergic receptor gene was tested, this polymorphism was significantly associated with 3th lumber and left femoral neck Z-score values in controls (p<0.05), but these associations were not detected in athletic groups (p>0.05). It is likely that Trp64Arg polymorphism in the ${\beta}_3$-adrenergic receptor gene is a genetic marker for the bone mineral density index in young men, but environmental factors such as exercise modify the significant effect of this polymorphism. Thus, our results suggest that Trp64Arg polymorphism in the ${\beta}_3$-adrenergic receptor gene may be applicable as a predictive marker for osteoporosis in Korean young men, and regular exercise may prevent the disadventageous effect of this polymorphism for bone mineral density in male athletic group.

  • Background: The fundamental responsibility of an anesthesiologist is to maintain adequate gas exchange. Failure to maintain a patent airway can result in brain damage or death. Generally, in patients with mandibular prognathism, who have the protruded mandible, the mask ventilation was thought to be not easy. The purpose of this study was to observe the degree of the difficulty of airway management in mandibular prognathism using some anatomic criteria for defining and grading difficulty of airway and difficulty of endotracheal intubation with direct laryngoscope. Methods: The observations and measurements are done to the 54 patients with mandibular prognathism, who were scheduled for corrective esthetic surgery. The case study is done to the 30 patients with normal mandible for control group. In all patients, mouth opening distance (MOD), mouse opening angle (MOA), mandibular length (ML), mandibular depth (MD), thyromental distance (TMD), thyromental area (TMA), Mallampati grades, and Cormack and Lehane grades are measured. T-test and Chi-square test are done (P < 0.05). Results: In the mandibular prognathism cases, the measurements of MD, TMD and TMA are more greater than those of controls (P < 0.05). Mallampati grades with tongue thrust are higher in the female mandibular prognathism cases than those of female controls. Most of the grades of the mandibular prognathism cases with Cormack and Lehane grading system are I or II being easy intubation cases (P < 0.05) Conclusions: In the patients of mandibular prognathism, the intubation with laryngoscope will be easer than that of normal mandible in general. It is for that their laryngeal aperture can be easily visible when the laryngoscope are used.

  • Objectives : The purpose of this study is to find out the correlation between the Vocal indicators and the 'Buzhongyiqi-Tang questionnaire' and the 'Chalder fatigue scale.' Methods : This study examined the mean value of each factor in the 'Buzhongyiqi-Tang Questionnaire,' 'Chalder fatigue scale' and the different voice indicators conducted on 81 healthy adult participants in relation to the results of the /a/ /e/ /i/ /o/ /u/ pronunciation test. Results : There was significant correlation between the pronunciation of /a/ /e/ /i/ /o/ /u/ vowels' F0 indexes and 'the Deficiency symptoms of Buzhongyiqi-Tang'. The results of the regression analysis showed the following significant findings for each pronouncing vowels: /i/ as a factor for 'the Deficiency symptoms of Buzhongyiqi-Tang'.; /a/ for 'the Consumptive fever of Buzhongyiqi-Tang'.; /i/ for 'the Vocal inflammation of Buzhongyiqi-Tang.; and /e/ as a factor of 'the Chadler physical fatigue'. Conclusions : The study showed a negative correlation between the Fundamental Frequency and the mean value of the questionnaire, which could be understood as higher the fatigue level, increased level of vocal vibration and higher pitch tone compared to the less fatigued group. We expect future studies to conduct research on methods to diagnose other illnesses using the vocal indicators based on the correlation between the vocal index and illnesses prescribed under traditional oriental medicine.

  • The aim of this study is to provide fundamental data on the development of dress shirts pattern appropriate for the body types of athletes. The research subjects are 257 athletes from wrestling, bodybuilding, weight lifting, Judo, canoe, rowing. In regards to the category used in the measurement of bust somatotype, there are 48 types directly measured, 4 types indirectly measured, 7 types calculated and 1 bodyweight of type, making it 60 categories in total. The bust somatotype of a sports athlete and general person were compared together and after examining the characteristics of the bust somatotype, the somatotype of sports athlete was divided according to drop. The results of the study are as follows: 1. Questionnaire Results of the questionnaire showed that 63.4% of the respondents chose dress shirt as the most uncomfortable upper garment for athletes. And as for the result of the most uncomfortable body part turned out to be 'the neck is tight'. 2. Somatotype Analysis Results of direct, indirect measurement and the average somatotype of 97 National standard physique were compared. The characteristics of somatotype of athletes with well-developed upper body are that they are taller and have longer upper body and arms than the general person. And also the width of the trunk is wider, the girth bigger and the waist measure relatively slimmer. Looking at sports by category, it we could see that wrestlers were the largest neck parameter and width. Bodybuilders were the largest body parts for most categories. Weight lifting and Judo athletes were the largest waist and buttock. Canoe and rowing athletes were the largest height and arm parts. Dividing the somatotype of athletes according to drop, 72.8% of the research group belonged to the body type that resembled the letter Y.

  • In this review, we have tried to summarize the evidence and molecular characterization indicating that $20{\alpha}$-hydroxysteroid dehydrogenase ($20{\alpha}$-HSD) is a group of the aldo-keto reductase (AKR) family, and it plays roles in the modulation and regulation of steroid hormones. This enzyme plays a critical role in the regulation of luteal function in female mammals. We have studied the molecular expression and regulation of $20{\alpha}$-HSD in cows, pigs, deer, and monkeys. The specific antibody against bovine $20{\alpha}$-HSD was generated in a rabbit immunized with the purified recombinant protein. The mRNA expression levels increased gradually throughout the estrous cycle, the highest being in the corpus luteum (CL) 1 stage. The mRNA was also specifically detected in the placental and ovarian tissues during pregnancy. The $20{\alpha}$-HSD protein was intensively localized in the large luteal cells and placental cytotrophoblast villus, glandular epithelial cells of the endometrium, syncytiotrophoblast of the placenta, the isthmus cells of the oviduct, and the basal part of the primary chorionic villi and chorionic stem villus of the placenta and large luteal cells of the CL in many mammalian species. Further studies are needed to determine the functional significance of the $20{\alpha}$-HSD molecule during ovulation, pregnancy, and parturition. This article will review how fundamental information of these enzymes can be exploited for a better understanding of the reproductive organs during ovulation and pregnancy.
