본 연구에서는 무분별한 개발로 인한 자연경관훼손의 예방을 목적으로 자연경관보존방안을 제정하기 위한 경관평가를 수행하였다. 우리나라에서의 경관평가는 개발계획에 따른 시각경관만을 평가하고 있는 현실이며, 경관의 생태적 본질까지 동시에 평가하지는 못하고 있는 실정이어서 이에 대한 대책이 요구되고 있다. 본 연구에서는 이를 위해 시각경관민감도와 생태경관다양성을 요소로 하는 경관평가를 진행하였다. 경관평가의 목적은 실질적인 보존지역을 설정하고 그에 따른 계획을 수립하기 위함이기 때문에 이앤 맥하그(Ian McHarg)의 도면중첩법을 적용한 지리정보시스템(Geographic Information System: GIS)를 활용하였으며, 생태경관다양도와 시각경관민감도를 측정하여 중첩분석하였다. 또한, 경관영향요소의 영향력분석을 통해 집중관리지역을 분석할 수 있었다.

본 연구는 치과의원에 내원한 환자의 치과서비스에 대한 차별감이 재이용의사에 미치는 영향을 파악하기 위하여 충청북도 J시 소재 치과의원에 내원한 만 20세 이상 환자 432명을 대상으로 2015년 3월 9일부터 2015년 3월 31일까지 설문조사를 실시하여 다음과 같은 결과를 얻었다. 재이용의사에 영향을 미치는 중요한 변수로는 치과 의료서비스 질의 의료진, 친절성, 병원 이미지, 이용 편의성, 및 서비스 가치, 치과 서비스에 대한 차별감이 있었고, 이 변수들의 전체 설명력은 78.2%이었다. 또한 고학력군, 월평균 가족수입 400만원 이상군, 사무직군, 임플란트 치료의 방문목적군, 주위소개군 뿐만 아니라 서비스 가치, 의료진, 환경시설, 이용 편의성, 친절성, 병원 이미지가 높을수록 유의한 관련성이 있었다. 따라서 치과서비스 제공자들은 환자들의 치과 서비스에 대한 차별감을 인지하여 외적인 요인뿐만 아니라 환자가 느끼는 차별감이 최소화 될 수 있도록 양질의 치과 서비스를 통해 이를 충족시키기 위한 노력이 필요하다고 본다.

Objectives: This study examined the statistical relevance of whether the systemic predisposing factors affect the prognosis of surgical treatment of bisphosphonate-related osteonecrosis of the jaw (BRONJ). All cases had undergone bone biopsies to determine the characteristics of the mechanisms of BRONJ by optical microscopy. Materials and Methods: The data included 54 BRONJ cases who underwent surgery and in whom bone biopsies were performed. The results of surgery were evaluated and the results were classified into 3 categories: normal recovery, delayed recovery, and recurrence after surgery. The medical history, such as diabetes mellitus, medication of steroids, malignancies on other sites was investigated for an evaluation of the systemic predisposing factors in relation to the prognosis. The three factors involved with the medication of bisphosphonate (BP) were the medication route, medication period, and drug holiday of BP before surgery. The serum C-terminal cross-linking telopeptide (CTX) value and presence of microorganism colony in bone biopsy specimens were also checked. Statistical analysis was then carried out to determine the relationship between these factors and the results of surgery. Results: The group of patients suffering from diabetes and on steroids tended to show poorer results after surgery. Parenteral medication of BP made the patients have a poorer prognosis after surgery than oral medication. In contrast, the medication period and drug holiday of BP before surgery did not have significance with the results of surgery nor did the serum CTX value and presence of microorganism colony. Necrotic bone specimens in this study typically showed disappearing new bone formation around the osteocytic lacunae and destroyed Howship's lacunae. Conclusion: Although many variables exist, this study could in part, predict the prognosis of surgical treatment of BRONJ by taking the patient's medical history.

Objectives : The aim of this study was to prepare the validity and relevance for National Health Insurance of Chuna manual therapy through measurement of resource-based relative value scale(RBRVS) scores. Methods : To prepare for National Health Insurance, we studied it about standardized classification of the practice and definition, and speciality by difficulty and safety of Chuna manual therapy. Results : Classification of the practice could be classified to 7 of Chuna manual therapy and 24 traditional manual therapy, it also categorized as one of 3 kinds(basic, simple, special). The RBRVS scores of Chuna manual therapy were measured to 283.28, 566.57 and 1133.14. Conclusions : This study could be used to basis data for National Health Insurance of Chuna manual therapy, but further studies must be needed more objective investigation and data to calculate RBRVS scores.

Purpose: This study was performed to investigate the level of ethical values and its related factors among some paramedic students. Methods: The subjects of this study were 480 paramedic students from five universities located in G-metropolitan city and J province. Data were collected using a self-administered questionnaire and analyzed using t-test, ANOVA, Pearson's correlations, and multiple regression analysis. Results: The mean scores of level of ethical values, academic self-efficacy and self-esteem were $3.70{\pm}0.45$, $3.15{\pm}0.42$ and $3.60{\pm}0.70$, respectively. In the correlation analysis, ethical value level was significantly positively correlated with self-esteem (r=.195, p< .001) and academic self-efficacy (r=.156, p= .001), of domains in academic self-efficacy, self-regulation efficacy (r=.230, p< .001) and confidence (r=.105, p= .022). In multiple regression analysis, self-esteem (${\beta}=.163$, p= .026), task ease preferences (${\beta}=-.350$, p< .001) and confidence (${\beta}=.403$, p< .001) were significantly related to ethical value levels. In addition, subjects willing to participate in the bioethics education showed higher relevance to ethical values than indifferent subjects (${\beta}=2.751$, p= .003). Conclusion: Concrete and systematic education will be needed in order to foster the establishment of ethical values of the paramedic students. Additionally, to fulfill their roles and obligations as emergency medical technicians, in the field, various educational curricula based on simulated cases in the university should be introduced.

In order to reduce the radiation exposure dose of the patient and to obtain accurate diagnosis results, the quality control of the diagnostic radiation generator must be conducted periodically In particular, bone density test equipment could be influenced by many factors, and it is far more important because inaccurate measurement would eventually affect the result value. However, the cross-correction phantom of DXA equipment is poorly penetrated due to lack of awareness of the industry and the high cost. Therefore, this study developed a BMD phantom using a 3D printer and Korean BMD phantom with low cost by cross analyzing Korean BMD value from The Korean National Health and Nutrition Examination Survey and evaluated it. The L1, L2, and L3 BMD values of phantoms produced with the 3D printer were measured to be $0.887{\pm}0.006g/cm^2$, $0.927{\pm}0.006g/cm^2$, and $0.960{\pm}0.005g/cm^2$, at 215 mm height and $0.882{\pm}0.011g/cm^2$, $0.914{\pm}0.005g/cm^2$, $0.933{\pm}0.008g/cm^2$ at 155 mm height displaying statistically significant relevance. The result suggests that a proper quality control and cross calibration of DXA device be possible and expected to be an essential data for various medical phantom manufacture development using 3D printer.

Importance: Over the past decade, catfish farming has increased in Southeast Asia. However, there has been no existing for pharmacokinetic data in the hybrid catfish (Clarias macrocephalus x C. gariepinus). Objective: This study was designed to evaluate the pharmacokinetic characteristics of oxytetracycline (OTC) in the hybrid catfish, following single intravascular (IV) or oral (PO) administration at a single dosage of 50 mg/kg body weight (BW). Methods: In total, 140 catfish (each about 100-120 g BW) were divided into two groups (n = 70). Blood samples (0.6-0.8 mL) were collected from ventral caudal vein at pre-assigned times up to 144 h (sparse samples design). OTC plasma concentrations were analyzed using high-performance liquid chromatography-photodiode array detector. Results: The pharmacokinetic parameter of OTC was evaluated using a non-compartment model. OTC plasma concentrations were detectable for up to 144 and 120 h after IV and PO, respectively. The elimination half-life value of OTC was long with slow clearance after IV administration in hybrid catfish. The average maximum concentration value of OTC was 2.72 ㎍/mL with a time at the maximum concentration of 8 h. The absolute PO bioavailability was low (2.47%). Conclusions and Relevance: These results showed that PO administration of OTC at a dosage of 50 mg/kg BW was unlikely to be effective for clinical use in catfish. The pharmacodynamic properties and clinical efficacy of OTC after multiple medicated feed are warranted.
