The purpose of this study is to provide a basis for nursing intervention strategies to promote quality of life in cancer patients. Therefore the study is designed to evaluate the effectiveness of perceived health status, self-esteem, health locus of control, self-efficacy, perceived susceptibility /severity, health promoting behaviors, and hope for quality of life. The sample was composed of 164 stomach cancer patients who visited outpatient clinics at a university hospital in Seoul. The following instruments were used in the study after some adaptation : Lawstone and others' Health Self-rating Scale, Rosenberg's Self-esteem Scale, Wallston and others 'Multidimensional Health Locus of Control Scale, Sherer & Maddux's Self-efficacy Scale, Moon's Health Beliefs Scale, Walker and others' Health Promoting Lifestyle Profile, Nowotney's Hope scale and Noh's Quality of Life Scale. Data were analyzed using a SAS program for Pearson correlation coefficients, descriptive correlational statistics and stepwise multiple regression. The results are as follows : 1. The scores on the quality of life scale ranged from 115 to 243 with a mean of 177.84(SD : 25.35). The mean scores(range 1-5) on the different dimensions were : emotional state 3.37 : economic life 3.47 : physical state & function 3.52 : self-esteem 3.66 : relationship with neighbors 3.37 ; family relationships 3.80. 2. There was a significant correlation between all the predictive variables and the quality of life (r=.20-.65, p<.01). 3. Stepwise multiple regression analysis showed that : 1) Self-esteem was the main predictor of quality of life and accounted for 46.9% of the variance in quality of life. 2) Perceived health status, hope and perceived susceptibility/severity accounted for 11.8%, 8.3%, 1.5% of the variance in quality of life, respectively. 3) Self-esteem, perceived health status, hope & perceived susceptibility /severity combined accounted for 68.5% of the variance in quality of life. In conclusion, self-esteem, perceived health status, hope and perceived susceptibility / severity were identified as important variables in the quality of life of cancer patients.

본 논문에서는 Dual oxide를 갖는 Nano-scale CMOSFET에서 각 소자의 Hot carrier 특성을 분석하여 두 가지 중요한 결과를 나타내었다. 하나는 NMOSFET Thin/Thick인 경우 CHC stress 보다는 DAHC stress에 의한 소자 열화가 지배적이고, Hot electron이 중요하게 영향을 미치고 있는 반면에, PMOSFET에서는 특히 Hot hole에 의한 영향이 주로 나타나고 있다는 것이다. 다른 하나는, Thick MOSFET인 경우 여전히 NMOSFET의 수명이 PMOSFET의 수명에 비해 작지만, Thin MOSFET에서는 오히려 PMOSFET의 수명이 NMOSFET보다 작다는 것이다. 이러한 분석결과는 Charge pumping current 측정을 통해 간접적으로 확인하였다. 따라서 Nano-scale CMOSFET에서의 NMOSFET보다는 PMOSFET에 대한 Hot camel lifetime 감소에 관심을 기울여야 하며, Hot hole에 대한 연구가 진행되어야 한다고 할 수 있다.

The present study performed subjective evaluation experiments using slides and scale down models in order to propose guidelines for lighting environment desirable for each behavior in the house. The evaluation measure was composed of 20 mood items and 15 behavior items. As for experiment methods, the slide experiment used SD method, and the scale down model experiment used Scheffe's paired comparison. The results of this study are as follows. 1) Desirable lighting environment for working and talking is active atmosphere. 2) Lighting environment desirable far relaxation is to heighten lighting contrast using candescent lamps and local lights. In other words, active atmosphere, which is desirable for working and talking, is not desirable for relaxation. 3) Lighting for working requires bright illuminance and high color temperature(6000k). 4) Lighting for relaxation requires somewhat low brightness regardless of color temperature. If the light is bright it is better to use lamps of low color temperature. 5) for conversation, bright illuminance is more desirable than dark one, and the most adequate color temperature is 4000K.

Form-ratio means the ratio of height/Width/Depth in 3-dimensions. The golden ratio or golden section is included as one of the form-ratio. We conducted two kinds of kansei experiments of cubic model and refrigerator varied from 1:1:1 to 1:1:3.66 on the scale of x:y:z. The subjects evaluate the form-ratios of 3-dimensional cubes and virtual products with SD-scale Kansei words(feelings and images). We applied the factor analysis to identify semantic space in cube model and virtual products. Finally, we compared with kansei structure of cube model and virtual product.

The Korean version of the Multidimensional Students' Life Satisfaction Scale for children(K-MSLSS) assesses children's subjective perceptions of Life Satisfaction(LS) in five conceptually relevant domains : Friends, School, Family, Living Environment, and Self. The purpose of the present study was to validate the five-factor structure of the K-MSLSS using Confirmatory Factor Analysis(CFA) procedures by means of the AMOS 7.0 statistical program. Of the 681 children(10.5 years, SD=1.1) recruited from three public elementary schools in Seoul 431 children were the calibration sample and 430 children were the validation sample. Results of the analyses found that the five-factor structure of K-MSLSS is applicable for use with Korean children from 9-12 years of age regardless of gender.

In this paper, quantization and inverse quantizatio unit, a sa component of MPEG-2 moving picture compression system, ar edesigned. In the processing of quantization, this design adopted newly designed arithmetic units in which quantization matrices and scale code was expressed with SD(signed-digit) code. In the arithmetic unit of inverse quantization, quantization scale code, which has 5-bits length, is splited into two pieces; 2-bits for control code, 3-bits for quantization data, and the method to devise quantization step size is proposed. The design was coded with VHDL and synthesis results in that it consumed about 6,110 gates, and operating speed is 52MHz.

The purpose of this study was to examine the feasibility of validating the Kaufman Assessment Battery for Children(K-ABC) with Korean preschoolers. Subjects were 197 preschoolers of 3,4 and 5 years of age. The mean of the MPC(Mental Processing Composite) scores was 111.7 and SD was 12.26. According to the item discriminant method, most subtests of Sequential Processing and the triangle subtest of Simultaneous Processing were significant, but the other subtests were insignificant. All subtests were highly correlated with MPC, and both the Sequential Processing Scale and Simultaneous Processing Scale were highly correlated with MPC; but the correlation between the two scales was low. Internal consistency was satisfactory on both scales(Cronbach' ${\alpha}$=.76 -.86). A further study is needed to diminish cultural discriminants and to include more samples from diverse subject groups.

Purpose: The purpose of this study was to identify the differences in preference for terminal care between hospitalized patients and nurses. Methods: A cross-sectional descriptive design was used in 79 patients and 107 nurses. The data were collected from August to October 2011, using the Preference for Care near the End of life Scale - Korean Version (PCEOL-K) with 5-point scale of 26 items. The reliability of the tool was Cronbach's ${\alpha}=.74$. Results: The mean score (SD) of PCEOL-K's sub-dimensions in nurses' priority was: (a) pain $3.70{\pm}0.63$, (b) spirituality $3.63{\pm}0.61$, (c) family $3.40{\pm}0.70$, (d) autonomous decision making $2.30{\pm}0.66$, and (e) decision making by healthcare professionals $2.14{\pm}0.64$. In patients' priority, the $M{\pm}SD$ score of each sub-dimension was: (a) pain $3.86{\pm}0.65$, (b) family $3.83{\pm}0.57$, (c) decision making by healthcare professionals $3.37{\pm}0.85$, (d) spirituality $3.01{\pm}0.80$, and (e) autonomous decision making $2.43{\pm}0.63$. Results indicated significant differences between nurses and patients regarding decision making by healthcare professionals (t=-11.28, p<.001), family (t=-4.66, p<.001), and spirituality (t=5.71, p<.001). Conclusion: The PCEOL-K of patients was higher than nurses'. A terminal care program for hospitalized patients at the end of life should be planned according to the results of PCEOL-K in nurses and patients.

본 논문에서는 옥천 및 창녕지역에서 총 24회 수행한 암반앵커 현장인발시험의 결과를 나타내었다. 시험앵커의 정착깊이는 1~6m로 서로다른 암반내에 설치하였다. 앵커의 대부분은 고강도 이형철근인 SD40-D51mm를 사용함으로써 다른 파괴가 일어나기 전에 암반파괴가 먼저 일어나도록 유도하여 암반의 인발저항력을 파악하고자 하였으며, 일부에서는 SD40-D32mm앵커를 설치하여 앵커의 파괴도 아울러 살펴보았다. 많은 시험에서 파괴는 항복에 이르는 극한하중까지 관찰할 수 있었으며, 암반파괴형상은 암반이 들어올려지면서 방사상으로 균열이 발달하는 형태를 나타내었다. 또한 시멘트그라우트와 텐던사이의 부착강도를 평가하고자 방식쉬이스가 설치된 앵커에 대해 실내실험을 실시하였다. 실험결과 텐던-그라우트 사이의 부착강도는 그라우트 일축압축강도의 18~25%로 나타났으며, 방식쉬이스에 의한 부착력 감소는 무시할 수 있을 정도로 작게 나타났다.
