Purpose The aim of this study was to analyze several technical and clinical factors associated with the successful management of postoperative leakage by percutaneous Foley catheter placement. Materials and Methods Thirty-two patients were included in this retrospective study. Postoperative gastrointestinal leakage was diagnosed by computed tomography (CT) and the patients underwent percutaneous Foley catheter placement into the leakage site through Jackson-Pratt tubes or imaging-guided methods. Clinical success was defined as successful Foley catheter removal without symptom recurrence within 1 week and the risk factors for clinical failure were analyzed. Results In all patients, percutaneous Foley catheter placement was successfully achieved without complications. Foley catheter was placed at a median of 10 days (range, 1-68) after the confirmation of leakage on CT. Clinical success was achieved in 26 of the 32 patients (81%). Systemic comorbidity (p < 0.001) and failed oral intake (p = 0.015) were the statistically significant risk factors for clinical failure. Conclusion Percutaneous Foley catheter placement can be considered an effective approach for the management of postoperative bowel leakage. The presence of systemic comorbidity and successful oral diet after Foley catheter placement are significant factors for successful clinical recovery.

The critical thinking has become gradually important in nursing education for the era of convergence. The literature review was undertaken to identify the study trends of critical thinking in nursing education in Korea. 75studies from 1996 to 2014 were reviewed. The studies related to critical thinking were highly increased from 2006. The study design was identified descriptive studies to path model. The predictors to critical thinking were an academic system, age, interpersonal relationship, academic achievement, the duration of clinical practice, satisfaction on nursing, self-esteem, self-efficacy, learning methods and so on. The consequence variables were clinical practice stress, cognitive stress, the ability of problem-solving, clinical competency, emotion control, communication competence. It is necessary to develop education programs and curriculum based on evidence from the researches for increasing critical thinking.

Objectives The purpose of this study is to develop a case study protocol to complete final version of Korean medicine clinical pathway (CP) by applying Korean medicine CP based on carpal tunnel syndrome Korean medicine clinical practice guidelines developed by clinical experts to clinical field. Methods After applying previously developed CP, 10-point Likert scale questionnaires on satisfaction of CP, appropriateness and improvement on out patient department (OPD) treatments are carried out in the 2^nd week of OPD treatment. An open-ended questionnaire is also carried out to ask if there is any requirement to be added or improved among CP interventions. Results Final version of CP is going to be completed based on the questionnaire, excluding articles of which average or median value is less than 5 from 10-point Likert scale. Conclusions This evidence-based case study protocol is expected to contribute development of carpal tunnel syndrome clinical pathway.

The optimum population of a society or country can be defined as 'the population growth path that maximizes the welfare level of the society over the whole generations of both the present and the future, under the paths allowed by its endowments of production factors such as technology, capital and labor'. Thus, the optimum size or growth rate of population depends on: (i) the social welfare function, (ii) the production function, and (iii)demographic economic interrelationship which defines how the national income is disposed into consumption(birth and education of children included) and savings on the one hand and how the demographic and economic change induced thereby, in turn, affect production capacities on the other. The optimum population growth path can, then, be derived in the process of dynamic optimization of (i) under the constraints of (ii) and (iii), which will give us the optimum population growth rate defined as a function of parameters thereof. This paper estimates the optimum population growth rate of Korea by: specifying (i), (ii), and (iii) based on the recent development of economic theories, solving the dynamic optimization problem and inserting empirical estimates in Korea as the parametric values. The result shows that the optimum path of population growth in Korea is around TFR=1.81, which is affected most sensitively, in terms of the size of the partial elasticity around the optimum path, by the cost of children, share of capital income, consumption rate, time preference, population elasticity of utility function, etc. According to a survey implemented as a follow up study, there are quite a significant variations in the perceived cost of children, time preference rate, population elasticity of utility across different socio-economic classes in Korea, which implied that, compared to their counterparts, older generation and more highly educated classes prefer higher growth path for the population of Korea.

The purpose of this study is to verify the path of the motivation, the flow, and problem gambling and intervention points. To this end, we verified the mediation effect of the motivation of the users outside sales offices influences the problem gambling through a flow and the moderated mediation effect of the frequency of the use of a bicycle racing tracks in that process. A total of 411 cases were analyzed using surveys conducted for one day on a weekday and weekend (September 13th and 15th 2018) for adults using an outside sales office in Jangan. According to the analysis, the causality of gambling by gambling motivation(amusement, excitement, avoidance, society, money) showed its effect positively by mediating the flow. The adjusted effect of the frequency of the use on the intermediary effect of the motivation ${\rightarrow}$ flow ${\rightarrow}$ problem gambling behavior, which is the main concern of this study, was found to be statistically significant. More specifically, the effect of adjusting the frequency of the use was statistically significant in both paths: motivation/flow and flow/problem gambling. It was also shown that, in the model with excitement, avoidance and social motivation, the adjustment of the frequency was only significant in the causal relationship between the flow and problem gambling. Based on these findings, this study made clinical and policy suggestions for intervention for gamblers and user protection regulations.

현재까지도 본질병의 원인체인 Eperythozoon에 대한 생활환 감염경로 및 매체등 역학적인 연구가 되어 있지 않은 상태이다. 더욱이 우리나라에서는 본증의 연구 조사가 거의 전국적 규모에서 이루어져 있지 않은 실정인데, 본인등이 건강돈으로 도살되는 성돈에서 $72\%$의 자연 감염율을 관찰할 수 있었으며, 대단위 양돈장에서 높은 자돈의 치사율을 보이는 본증의 유행상을 경험한 점을 감안할때 앞으로 우리나라에서 효과적인 양돈사업의 육성을 위해서 본질병에 대하여 더욱 관심과 연구를 집중해야 될 줄 믿는다. 또한 본 원인균은 일반 전염병 치료제로 많이 애용되는 Sulfa제나 항생제에 대하여 전혀 감수성이 없으며 매독성이 비소제인 Arsphenamine만이 특효가 있다. 점도 임상수의사들이 관심을 기울여야 할 사항이면, 보다 저독성이며 효과적인 치료제 개발도 시급히 요구되는 실정이라 하겠다.

HBV는 인체에 감염하여 간염, 간경변 및 간암을 유발하는 hepadnaviruses의 일종으로써 임상적으로 매우 중요한 바이러스이다. 그러나 이 바이러스에 의한 간암(HCC)의 발생 메커니즘은 아직 불확실하다. 최근에는 HBV의 X 단백질(HBx)이 간암 발생에 중요한 역할을 수행하는 것으로 보고되고 있다. HBx 단백질은 전사 활성인자(transcriptional activator)로써 숙주세포의 유전자발현에 영향을 미치어 세포증식 및 분화에 영향을 줄 수 있다. 본 연구에서는 HBx 단백질이 NIH 3T3 cell의 증식 및 형질전환에 미치는 영향을 조사하였다. HBx 단백질을 발현하는 세포주는 정상세포에 비하여 증식 속도가 2배 정도 빠르며, soft agar assay 결과에 의하면 대조군과 비교하여 더 많은 수의 colony를 형성하였다. 또한, 이들 HBx 발현 세포들은 접촉 저해 능력을 상실하여 HBx가 세포 형질 전환 능력을 가짐을 알수 있다 또한 HBx 발현 세포주에 있어서 p21의 RNA 및 protein수준이 정상세포에 비하여 낮으므로 HBx에 의한 증식 촉진 및 세포 형질 전환이 p21을 매개하여 이루어 짐을 알 수 있었다. HBx에 의한 p21 유전자의 발현 감소는 p21의 전사 수준에서 이루어지며 이는 p53-비의존적 경로에 의하여 이루어졌다.

This study sought to examine the factors influencing clinical competence of dental hygienists. A survey on burnout, critical thinking tendency, self-esteem, self-leadership, professional self-concept and clinical competence was conducted with 254 dental hygienists using self-administered questionnaires. Correlation analysis was performed between study variables, and linear regression analysis identified factors influencing clinical competence. To determine a causal relationship among these factors, a path analysis was conducted at the 0.05 level of significance. Relationships among research variables showed significant positive correlations (p<0.01). Self-esteem, self-leadership, and professional self-concept were found to influence clinical competence (p<0.01). A causal relationship was also found among variables influencing clinical competence. Burnout and critical thinking had an indirect effect, whereas self-esteem, professional self-concept, and self-leadership had both direct and indirect effects. In conclusion, important factors influencing clinical competence of dental hygienists include self-esteem, self-leadership, and professional self-concept. Based on these findings, programs to enhance clinical competence of dental hygienists should be developed.
