  • Nephrogenic diabetes insipidus (NDI) is a disorder in which the secretion of antidiuretic hormone is normal, but the response of the renal collecting tubules to vasopressin is impaired. Compared with acquired NDI (a-NDI), which is secondary to chronic bilateral incomplete urinary tract obstruction with hydronephrosis, congenital NDI (c-NDI) is a very rare heritable disorder that usually follows the X- linked recessive pattern. Clinical symptoms of c-NDI can be non specific, and often the disease ultimately results in failure to thrive, or mental retardation. Recently, the diagnosis can be confirmed by direct sequencing analysis of the peripheral blood specimens. The long-term results of treatment for c-NDI are not satisfactory. Reports on the follow up of c-NDI cases are rare and there is no report on the cases treated with combinations of three drugs. We report herein a case of severe c-NDI in an 8 year-old-boy with a severely dysconfigurated urinary tract system. The patient and his mother showed a frameshift mutation on the AVPR2 gene on chromosome Xq28:.847_851delTGCTG (p.C283fsX90). The patient showed normal growth and development by treatment with combinations of hydrochlorothiazide ($65mg/m^2$), amiloride (0.3 mg/kg/d) and indomethacin ($100mg/m^2$), yet after five years he needed adjuvant cystostomy to relieve him from the residual symptoms of urgency with polyuria.

  • The transport of landfill leachate in the subsurface formations of unlined landfill sites is considered. The impacts of hydrogeological and chemical heterogeneities on the leachate transport are assessed by examining the results from a series of Monte-Carlo simulations. The landfill system simulated in this study is hypothetically represented with three levels of spatial variability for the hydrogeological and chemical parameter; (1) homogeneous hydraulic conductivity (K) and distribution coefficient ($K_d$), (2) K heterogeneity only, and (3) combined heterogeneities of K and $K_d$. To calculate the transport of leachate through negatively-correlated random hypothetical K-$K_d$ fields generated using geostatistical input parameters, a saturated flow model is linked with a contaminant transport model. Point statistic values such as mean, standard deviation, and coefficient of variation of the concentration were obtained from 100 Monte-Carlo trials. Results of point statistics show that the heterogeneities of K and $K_d$ in the landfill site prove to be an important parameter in controlling leachate concentrations. Consideration of combined K and $K_d$ heterogeneities results in enhancing the variability of contaminant transport. The variability in the leachate concentration for different realizations also increases as the distance between source and monitoring well increase.

  • Aims: Dysfunction of the host immune system in cancer patients can be due to a number of factors, including lymphocyte apoptosis. Several studies showed that $Foxp3^+T$ cells take part in inducing this process by expressing FasL in tumor patients. However, the relationship between apoptosis, $CD8^+T$ cells and $Foxp3^+T$ cells in HCC patients is still unclear. The present study was designed to investigate the correlation between apoptosis levels and Fas/FasL expression in $CD8^+T$ lymphocytes and $Foxp3^+T$ cells in patients with HCC. Methods: $CD8^+T$ cells and $CD3^+Foxp3^+T$ cells were tested from peripheral blood of HCC patients and normal controls and subjected to multicolor flow cytometry. The expression of an apoptosis marker (annexin V) and the death receptor Fas in $CD8^+T$ cells and FasL in $CD3^+Foxp3^+T$ cells were evaluated. Serum TGF-${\beta}1$ levels in patients with HCC were measured by enzyme-linked immunosorbent assay. The relationship between apoptosis and Fas expression, as well as FasL expression in $CD3^+Foxp3^+T$ cells was then evaluated. Results: The frequency of $CD8^+T$ cells binding annexin V and Fas expression in $CD8^+T$ cells, were all higher in HCC patients than normal controls and the proportion of apoptotic $CD8^+T$ cells correlated with their Fas expression. Serum TGF-${\beta}1$ levels correlated inversely with $CD3^+Foxp3^+T$ cells. Conclusions: Fas/FasL interactions might lead to excessive turnover of $CD8^+T$ cells and reduce anti-tumor immune responses in patients with HCC. Further investigations of apoptosis induction in $Fas^+CD8^+T$ cells in vitro are required.

  • New ten N-[1-(benzotriazol-1-yl)alkyl]aniline(4) derivatives were synthesized and the crystal structure of 4h was shown by X-ray crystallography and the absolute configuration has been assigned as S form. The molecule crystallizes in the monoclinic system, space group $P2_{1}/n$. And the molecules in the crystal are linked with each other through the hydrogen bond $(N_{11}-H_{11}{\cdots}N3)$ with distance $2.300(11){\AA}$ The fungicidal activity($pI_{50}$) in-vitro against Botrytis cineria (BC), Phytophthora casici (PC) and Sclerotium cepinorum (SC) were determined by the agar dilution method. The structure activity ralationships (SAR) between structure of 4 and the activity were studied using a physicochemical parameters of substituents and multiple regression technique. Among these compounds, only the bromo group substituent(4f) showed higher activity, which depend on the hydrophobic(${\pi}$) of substituents. The relative orders of the activity are SC>BC> and PC, respectively. This implies that the activity is affected by the hydrophobic(${\pi}$) nature of the Z group rather than the X group. Linear free energy relationships(LFER) on the fungicidal activity with substituents has been also discussed.

  • The purpose of this paper is to propose a new security orchestration service model by combining various security solutions that have been introduced and operated individually as a basis for cyber security framework. At present, in order to respond to various and intelligent cyber attacks, various single security devices and SIEM and AI solutions that integrate and manage them have been built. In addition, a cyber security framework and a security control center were opened for systematic prevention and response. However, due to the document-oriented cybersecurity framework and limited security personnel, the reality is that it is difficult to escape from the control form of fragmentary infringement response of important detection events of TMS / IPS. To improve these problems, based on the model of this paper, select the targets to be protected through work characteristics and vulnerable asset identification, and then collect logs with SIEM. Based on asset information, we established proactive methods and three detection strategies through threat information. AI and SIEM are used to quickly determine whether an attack has occurred, and an automatic blocking function is linked to the firewall and IPS. In addition, through the automatic learning of TMS / IPS detection events through machine learning supervised learning, we improved the efficiency of control work and established a threat hunting work system centered on big data analysis through machine learning unsupervised learning results.

  • Adolescent health is considered to contribute to health promotion in the home and community in the near future as well as individual health. However, adolescent health has been neglected from education field because of competitive school education focused on the university entrance examination That's why I suggest in this study that we should pay much more attention to adolescent health condition and try to make It better, in terms of man-power development and life-health promotion for nation development The purposes of this study are as follows First, to look into a variety of adolescent health problems Second, to find out the situation and problems of current adolescent health promotion and school health education Third, to make an effort to find, based on the current situation, various developments of adolescent health promotion and school health education in terms of practical, political and environmental change There are used study methods as adolescent-related, school heath-related literature review and anlysis of statistical data The results and suggestions are as follows Teenagers have a great variey of health problems including most Important physical, mental and social developments Recently, chronic diseases, emotional problems, health-risk behaviors linked With adolescents are on increase The complicated disorders of physical, mental, social health rather than paricular aspects of health or health-behavior problems influence adolescent health problems adolescence is regarded as the period when most health-related behaviors are formed. Therefore, adolescent health promotion would he assured by developing the ability of controlling multi-dimensional health determinants in the early stage. Health promotion is a positive concept that each individual, family and community makes real efforts to improve their health To achive this, we need health educational, organizational, political and environmental supports. Adolescent health promotion in Korea has been systematically treated in the category of school health Current school health services have had lots of systemic, constitutional, administrative and educational flaws Accordingly, I'm concerned that we can afford to accept a variety of adolescent health needs However, I would say that if were not to make those flaws better, it's certain that Korean national competitive power and the quality of the lives of most Koreans Will he threatened someday We have to develop Comprehensive School Health Crriculum(CSHC) and set up its standards to Improve adolescent health. CSHC is an organizational and costant process. CSHC means an Important part of overall curriculums. In addition, I could say that it's an Important school health education acivity including current school health services-health care service and school health environment. In conclusion, in order to develop CSHC, we require school nurse's role changes, establishment and management of intergrated subject of health education, striking revision of school health law(or legislation of school health promotion law), reorganization of administration system, big changes in curriculum for school health educators.

  • The purpose of this research is to analyze the performance of national R&D projects and to find out measures to improve the performance indicators, focusing on energy HRD projects. The main analysis target is 86 energy manpower projects supported since 2010. The performance indicators of the energy HRD projects are related to the research capacity, the number of emission workers, industry-university linkage, job creation and so on, and analyzed by using the 11 indicators of human resource performance index called KPI index. As a result of analyzing the attainment level of the proposed target by task, the index with the highest achievement level is the corporation linkage rate, and the index with the lowest achievement level is the participating company employment. As a result of examining the effects of job creation in company - linked activities, it was found that the greater the number of participating companies in the business, the greater the employment creation effect of the number of internships. As a result of the above analysis, the following policy alternatives are proposed. First, it is necessary to consider adding indicators that can express the quality performance of the business and performance indicators that can express actual business linkages. Second, it is necessary to strengthen the management of differentiated performance indicators according to policy performance targets and major target groups. Third, it is necessary to improve information input and accumulation system along with improvement of performance index.

  • Objectives : Obesity has been linked to various psychological problems as well as medical complications, especially among adolescents. Previous studies have suggested an association between body weight and depression or self-esteem ; however, there has been little evidence on self-perception of weight and mental health. The aim of this study was to examine the association of perceptional weight status with mental health in Korean adolescents. Methods : This study was based on data obtained from the third Korean National Health and Nutritional Examination Survey (2005). The study sample consisted of 583 adolescents (268 boys, 315 girls) aged 12-18 years, who had completed the health survey, the health examination, and the nutritional survey. Participants were divided into two groups based on the actual or perceptional weight status: non-obese and obese. Questionnaires for stress, depressive mood, and suicidal thoughts were utilized as mental health indicators. Results : The agreement between actual and perceptional weight status was moderate (k value, 0.585 ; p<0.01). The influencing factors for the discrepancy between actual and perceptional weight status were body mass index of subjects and their parents' education. The obese group was likely to have higher stress levels and more experience of depressive mood or suicidal ideation in regard to both actual and perceptional weight status. A multiple logistic regression analysis revealed that girls who had perceived themselves as obese were more likely to have an experience of depressive mood than other girls (unadjusted OR, 4.98 ; adjusted OR, 5.15). Conclusion : An experience of depressive mood was significantly associated with the perception of weight status and not actual weight status in Korean female adolescents.
