This study explored differences in how medical and surgical patients compare on the degree of hospital stress and their subjective physical status. Subjects were 343 medical and surgical patients in five university hospitals in Seoul and Taegu. They responded to the Hospital Stress Rating Scale and a self-report on physical status. The controlled variables were age, education, number of previous hospitalizations and seriousness of the illness. Medical and surgical patient differences on nine factors of the hospital stres scale and nine areas of physical conditions were reported as follows edplored : 1. 1) There was not a statistically significant difference at the .05 level in the total mean score for hospital stress between medical patients and surgical patients. 2) The mean score of the factor lack of information (M＝2.308) for medical patients was higher than the mean score (M＝2.064) of the surgical patients. 3) The mean scores of the factor of discomfort (M＝2.130), loss of independence (M＝1.889) for surgical patients were higher than for medical patients. 2. 1) There was a statistically significant difference at the .05 level in the total mean score for physical status between medical patients and surgical patients. 2) The mean scores were lower in subjective physical status for surgical patients(S) than for medical patients (M) ; stomach condition (S : M＝2.8433, M : M＝3.0-000), self-assistance(S : M＝3.0373, M : M＝3.4498), movement (S : M＝2.6716, M : M＝3.2392), interest in your surroundings (S : M＝3.0522, M : M＝3.2632). 3. Patients scoring high on the subjective physical status such as sleep, appetite, stomach condition bowel condition and urination states had higher scores in hospital stress than with patients scoring low on those subjective Physical status. The results suggest that subjective physical status might be on expression of hospital stress. Also patients with high scores in subjective physical statas might be predicted have a high level of stress on admission. And surgical patients had a higher level of hospital stress than medical patients.

Purpose In this study, radiation workers who work in nuclear medicine department were analyzed to find the cause of differences of radiation exposure from General Characteristic, Knowledge, Recognition and Conduct, especially females working on nuclear medicine radiation, in order to pave the way for positive defense against radiation exposure. Materials and Methods The subjects were 106 radiation workers who were divided into two groups of sixty-four males and forty-two females answered questions about their General Characteristic, Knowledge, Recognition, Conduct, and radiation exposure dose which was measured by TLD (Thermo Luminescence Dosimeter). Results The results of the analysis revealed that as the higher score of knowledge and conduct was shown, the radiation exposure decreased in female groups, and as the higher score of conduct was shown, the radiation exposure decreased in male groups. In the correlation analysis of female groups, the non-experienced in pregnancy showed decreasing amount of radiation exposure as the score of knowledge and conduct was higher and the experienced in pregnancy showed decreasing amount of radiation exposure as the score of recognition and conduct was higher. In the regression analysis on related factors of radiation exposure dose of nuclear medicine radiation workers, the gender caused the meaningful result and the amount of radiation exposure of female groups compared to male groups. In the regression analysis on related factors of radiation exposure dose of female groups, the factor of conduct showed a meaningful result and the amount of radiation exposure of the experienced in pregnancy was lower compared to the non-experienced. Conclusion The conclusion of this study revealed that radiation exposure of female groups was lower than that of male groups. Therefore, male groups need to more actively defend themselves against radiation exposure. Among the female groups, the experienced in pregnancy who have an active defense tendency showed a lower radiation exposure. Thus, those who have never been pregnant need to have a more active defensive conduct for the future possibility of pregnancy.

Objective : This study aims to investigate the relationship between addictive mobile phone use and post-traumatic stress disorder (PTSD) symptoms in bullies who experienced school violence. Methods : The study subjects consisted of 97 adolescents in The Foundation for Preventing Youth Violence after school violence. The participants conducted self-report questionnaire for addictive mobile phone use and Impacted Event Scale-revised-Korean version (IES-R-K). Partial correlation and multiple logistic regressions were performed. Results : The scores related to addictive mobile phone use were correlated with total score (r=0.21, p=0.04), avoidance score (r=0.21, p=0.04) and intrusive score (r=0.26, p=0.01) related to PTSD symptoms on the IES-R-K. Intrusive score related to PTSD symptoms on the IES-R-K were significant risk factor for addictive mobile phone use (O.R=1.25, 95% CI=1.12-1.39). Conclusion : This data supports that PTSD intrusive symptoms could be predictable factor of addictive mobile phone use. An appropriate intervention about PTSD symptoms might play a useful role in preventing addictive mobile phone use in bullies of school violence.

Objective : Trauma has been a controversial issue although it has been considered to be a major factor for the temporomandibular disorder(TMD). We evaluated the relationship between macrotrauma or microtrauma and TMD. Methods : This study was performed in patients with TMD undergoing treatment at SNUBH from October 2006 to January 2007. Sixty one male patients and 166 female patients(total 227) were included and the average age was 34 years(ranging from 14 to 85 years). We investigated the possible etiologic factors, diagnosis and treatment with the review of medical records and radiography. Chronic pain, depression, somatic score(including pain item), somatic score(excluding pain item) were evaluated on the basis of diagnostic index from the Research Diagnostic Criteria on TMD. Results : Eighteen patients(7.9%) out of 227 patients suffered from TMD as a result of macrotrauma. Ninety four(41.4%) patients had microtrauma and six patients(2.6%) had both macro- and microtrauma(etiologic factor). The main symptoms included pain. joint noise and mouth opening limitation while the other symptoms were headache and tinnitus. The patients had suffered from TMD for average 41 weeks (ranging from 1 to 480 weeks). 116 patients took splint as a major treatment. As a prognosis, 19 patients(8.4%) recovered completely. 26(11.0%) had improvement and 181(80%) had persistent symptoms. 1 patient(0.4%) underwent an arthroplasty. Diagnostic index from RDC chart showed that macrotrauma was the highest score(except depression score) among the other etiologic factors. Conclusion : This study showed that macro- and microtrauma can be considered to be the major etiologic factors of TMD, which also affect the chronic, depression and somatic discomfort.

Objectives: TNM staging, especially for lymph node metastasis, is the scoring system most widely used among prognostic factors for cancer survival. Several biomarkers have been studied as serologic markers, but their specificity is low and clinical applications are difficult. This study aimed to establish a scoring system for patients with oral squamous cell carcinoma (OSCC) using platelet (PLT) and mean platelet volume (MPV) levels measured postoperatively and to evaluate their significance as prognostic factors. Materials and Methods: We studied 40 patients admitted to the Department of Oral and Maxillofacial Surgery of Dankook University Hospital who were diagnosed with primary OSCC histopathologically between May 2006 and May 2012. Clinical pathological information obtained from the medical records of each patient included age, sex, height, weight, tumor location, degree of differentiation, tumor diameter, lymph node metastasis, TNM stage, and other test values including white blood cell, MPV, PLT, C-reactive protein (CRP), and albumin obtained through a test conducted within 7 days before surgery. Count of platelet (COP)-MPV Score: Patients with both PLT and MPV values below the cut-off values were defined as score 0 (group A). Patients with at least one of the two higher than the cut-off value were defined as score 1 (group B). Results: Univariate analyses showed N-metastasis, COP-MPV (A vs B), PLT, platelet-lymphocyte ratio, and CRP were statistically significant prognostic factors. A multivariate Cox proportional hazards model showed N-metastasis (hazard ratio [HR] 6.227, P=0.016) and COP-MPV (A vs B) (HR 18.992, P=0.013) were independent prognostic factors with a significant effect on survival. Conclusion: COP-MPV score is a simple and cost-effective test method and is considered a more effective prognostic factor than other considered factors in predicting the prognosis of OSCC patients.

프로젝트의 특성을 고려한 건설공사의 입찰방식 선정은 매우 중요한 요소이며, 발주자와 시공자 모두의 입장에서 공공건설공사에서 입찰방식의 이해는 그 중요성이 매우 크다. 설계시공일괄방식은 국내에서 흔히 턴키라 불리며 설계에 신기술을 적용할 수 있고 발주자의 리스크 관리가 용이하여 대형 공공건설공사에 많이 적용되는 입찰방식이다. 이 입찰방식에는 낙찰자 선정에 영향을 미치는 단 2개의 영향인자(설계점수, 가격점수)가 있어 각 영향인자 간 영향력에 대한 이해력이 중요함에도 불구하고 관련된 연구는 미흡한 실정이었다. 본 연구는 국내 공공공사의 다양한 입찰데이터를 분석하여 영향인자의 영향력을 분석하고 입찰전략 수립에 참고할 수 있는 근거를 제공하고자 한다. 연구 결과, 기술강조형, 가격강조형, 균등평가형 이 세가지 가중치 평가방식 모두 입찰자평가 순위에 더 많은 영향을 주는 요소는 설계점수인 것으로 나타났다. 또한 계약금액의 조정이 용이하지 않은 입찰방식 자체의 특징 및 총점 차등제 등 입찰평가구조로 인해 설계점수와 가격점수 간 상관관계는 크게 나타나지 않음을 확인할 수 있었다.
