Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

조선시대의 선비들은 평생동안 글읽기와 글쓰기를 그들 삶의 한 부분으로 자리매김하며 살았던 계층이라 할 수 있다. 입신양명을 위한 벼슬에 오르기까지 선비들은 부단히 경저 읽기와 글쓰기를 연마하였고, 과거를 통해 벼슬에 올라 대부가 된 후에도 글읽기와 글쓰기는 계속되는 것이 상례였다. 또한 선비들은 자신의 세계 인식과 관점. 태도를 드러내는 중요한 방편으로 글쓰기를 선택, 활용하였다는 점에서도 특이한 존재였다. 선비들에게 글읽기와 글쓰기는 그들의 삶과 밀접한 관련을 가졌음을 알 수 있으며, 그들에게 글읽기와 글쓰기는 별개의 행위가 아니었다고 할 수 있다.

Typical goals of parent education include information sharing, skill building, self-awareness, problem solving. But Most programs for parents with young children has been focused on information transmissions about child rearing and education and skill building. By reviewing related literatures, It needs that parents understand the importance of self-awareness and self-reflection on their parenting to be more efficient. That is, reflection is the essential process in parenting to alter their mistaken role performance and imperative process to try self-directed and critical practitioner about the amount information of the world. The concepts like reflective thinking would be the key themes of the program.

Purpose : To assess the width of the labial alveolar bone of the incisive canal and the width of the incisive canal on spiral computed tomographic images of the anterior portion of the maxilla. Materials and Methods : Study materials included 38 CT scans taken for preoperative planning of implant placement. Axial cross-sectioned image entirely showing the incisive canal was selected and scanned with 600 DPI resolution. The width of the labial alveolar bone of the incisive canal at an orifice to the oral cavity, middle portion, and an orifice to the nasal cavity and the diameter of the incisive canal at the middle portion were determined by two specialist using Digora for Windows 2.1. The statistical analyses were carried out using SPSS 12.0.1. Results : When the maxillary central incisors remained, the mean labial alveolar bone width were 6.81±1.41 mm, 6.46±1.33 mm, and 7.91±1.33 mm. When the maxillary central incisors were missed the mean width were 5.42±2.20 mm, 6.23±29 mm, and 7.89±2.13 mm. Conclusions : The labial alveolar bone width at middle portion and an orifice to the nasal cavity were of no statistical significant difference according to presence of the maxillary central incisors (P>0.05). The width between oral cavity and nasal cavity, middle portion and to nasal cavity revealed statistically significant difference (P<0.05).

This study formulates economic evaluation model of ecotourism tourism investment project used by fuzzy set theory. In this paper, we first consider the elementary concepts, in the mathematics of finance, present value and future value, In all cases the cash amounts, interest rates and number of compoundings may all be fuzzy and we used both triangular and trapezoidal shaped fuzzy numbers. Two commonly used model of comparing mutually exclusive investment projects are net present value(NPV), In the NPV method, one finds the present value of all future net returns discounted at the appropriate discounted rate, minus any intial cash outlays. If we have a number of investment proposals under consideration with cashflows, one ranks these proposals with from highest NPV to lowestNPV and selects investments in that order until the investment capital cost of is exhausted. At first glance this procedure appears sound but do not forget that all future cashflows have to be estimated and that interest rate may also be estimated. The results in this paper indicate a successful application of fuzzy set techniques to economical evaluation of tourism investment project. Based on this success one would think that there are many other areas in tourism economics and tourism corporate finance that are awaiting extension to fuzzy set theory.

Smoking damages nonsmoker's health who have been exposed to passive smoking as well as smoker's own health. Passive smoking can cause serious health damage to particular groups, such as the old aged, children and pregnant women. The purpose of this study is to investigate the relationship between nicotine concentrations in environmental tobacco smoke (ETS) and urinary cotinine concentrations of nonsmokers exposed to ETS, and to provide basic information related to health risk assessment. The results of this study were summarized as follows: 1. When 180 cigarrette were smoked during 5 hours (high concentrations exposure) in 132 m³ chamber, mean concentrations of nicotine in ETS showed 263.52㎍/m³±51.93. When 45 cigarretts were smoked (low concentrations exposure), it was 69.43±8.96㎍/m³. 2. The urinary cotinine concentrations of each times (0, 2.5, 5, 17 and 24 hours) in nonsmokers ranged from 0.27~12.52ng/ml in high concentrations exposure and 0.22~2.28ng/ml in low concentrations exposure. Mean while the total urinary cotinine concentrations during 24 hours ranged from 11.62~31.65㎍/ml in high concentrations exposure and 3.45~5.64ng/ml in low concentrations exposure. 3. The correlation equation and coefficient between cotinine concentrations in nonsmokers' urine(y) and nicotine concentrations in ETS(x) was y=0.421+0.0171x and 0:875 (p<0.01) respectively. 4. The quantity of nonsmokers' smoking exposure by passive smoking can be assumed as based on the estimation of nicotine concentrations in ETS by measuring cotinine concentrations of nonsmokers' urine.

The purpose of this study was to compare and to evaluate the combination use of 5 kinds of dentin adhesiye systems and 5 kinds of composite resins using micro-shear bond test. Five adhesive systems (Prime & Bond NT (PBN), Onecoat bond (OC), Excite (EX), Syntac (SY), Clearfil SE bond (CS)) and five composite resins (Spectrum (SP) Synergy Compact (SC), Tetric Ceram (TC), Clearfil AP-X (CA). Z100 (Z1)) were used for thing study (5×5 = 25group, n = 14/group). The slices of horizontally sectioned human tooth were bonded with each bonding system and each composite resin, and tested by a micro-shear bond strength test. These results were analyzed statistically. The mean micro-shear bond strength of dentin adhesive systems were in order of CS (22.642 Mpa), SY (18.368 MPa), EX (14.599 MPa), OC (13.702 MPa), PBN(12.753 MPa). The mean bond strength of self-etching primer system group (CS, SY) in dentin was higher than that of self-priming adhesive system groups (PBN, EX, OC) significantly (P<0.05). The mean bond strength of composite resins was in ordel of SP (19.008 MPa), EA (17.532 MPAa), SC (15.787 MPa), TC (15.058 MPa), Z1 (14.578 MPa) Micro-shear bond strength of SP was stronger than those of other composite resins significantly (P < 0.05). And those of TC and Z1 were weaker than other composite resins significantly (P < 0.05). No difference was found in micro-shear bond strength of composite resin in self-etching primer adhesive system groups (CS, SY) statistically. However, there was significant difference of micro-shear bond strength of composite resin groups in self-priming adhesive systems group (PBN, EX, OC). The combination of composite resin and dentin adhesive system recommended by manufacturer did not represent positive correlation. It didn't seem to be a significant factor.
