Objectives : The Internalized Stigma of Mental Illness (ISMI) scale designed to measure the subjective experience of stigma with sub-scales measuring Alienation, Stereotype Endorsement. Perceived Discrimination, Stigma Resistance, and Social Withdrawal. The purpose of this study was to examine the reliability and validity of the Korean version of ISMI. Methods : The subjects were 194 schizophrenic patients and 205 peoples with depressive disorder. K-ISMI, CES-D (The Center for Epidemiologic Studies Depression Scale) and Self Esteem scale were performed. Results : Results showed that the ISMI had high internal consistence and split-half reliabilities. The internal consistency coefficients (Cronbach alpha) of each subscale ranged from .83 to .93. The validity of the ISMI was investigated by principal axis factoring analysis, yielding 5 factors of alienation, Perceived discrimination, negative stereotype, stigma resistance, devaluation and social withdrawal. 5 subscales explained 60.67% of total variance. Concurrent validity was supported by comparisons against scales measuring related constructs. As expected, the ISMI had positive correlations with CES-D, and it had negative correlation with self-esteem scale. Subsidiary analysis showed that schizophrenic patients showed higher internalized stigma than depressed patients. Conclusion : Overall, the findings support the utility of ISMl as a tool to evaluate internalized stigma of persons with mental illness. Interventions that can lessen internalized stigma may well hasten the recovery process in individuals with mental illness.

In order to grasp how the indoor air levels affect on job satisfaction of beauty salon workers, we analyzed air environment levels of 30 beauty shops in Pusan and surveyed questionnaires of 130 persons who have worked there. The indoor temperature, relative humidity, discomfort index, and affective temperature were in comfort zone. Most measured values in the afternoon were higher than in the morning. Carbon dioxide concentration(1,115.6±766.7ppm even for A.M.) and monoxide(13.0±58.78ppm only for P.M.) were higher than safety standards(1,000 and 10 ppm, respectively). The indoor dry bulb temperature was positively correlated with discomfort index, globe and effective temperature(r=0.961, 0.665, and 0.957, respectively), while air velocity negatively with carbon di- mono-oxide and suspended dust quantity(r=0.416, -0.276, and -0.372, respectively). Backward stepwise regression equation showed that job satisfaction was affected by indoor air levels and environment recognition: Job satisfaction = 106.101 - 1.451(Environment recognition) + 4.137(Job responsibility) + 3.051(Job recommendation) - 4.008(Job renunciation) + 12.329(Relative humidity in the afternoon) + 12.378(Noise in the afternoon). From these results we conclude that the indoor physical environment plays a significant role in job satisfaction of beauty salon workers.

Purpose : To observe the histopathological changes following irradiation on the wound healing after tooth extraction in the rachitic rats. Materials and Methods : In order to carry out this study, the rats were divided into four groups: Group 1 (normal diet/non-irradiation group), Group 2 (normal diet/irradiation group), Group 3 (rachitogenic diet/non-irradiation group), and Group 4 (rachitogenic diet/irradiation group). Rachitic changes were induced with rachitogenic diet No. 2 (high calcium, low phosphorus, and Vitamin D deficient diet) for 5 weeks. After the extraction of both maxillary first molars of the rats in Group 2 and 4, the head and neck of the rats were irradiated with single absorbed dose of 10 Gy. The rats were sacrificed at the 1st, 5th, 10th, and 15th day after tooth extraction. The specimens including the extraction wound were sectioned, stained with the hematoxylin-eosin and Masson's trichrome method and examined under the light microscope. Results : In the Group 2, the amount of newly formed bone trabeculae on the periphery of extraction socket and osteoblastic activity were reduced. In the Group 3, epithelial fusion was not revealed on the 5th day after toothe extraction and growth rate of osteoid formation was reduced. In the Group 4, necrotized tissue at the outer surface of extraction socket and destructive changes on the alveolar bones were noted on the 10th day. Epithelial fusion was not revealed and large amounts of osteoclast were noted on alveolar bone on the 15th day. Conclusion : The healing process of wound after tooth extraction was retarded by irradiation and especially in the rachitic rats. (Korean J Oral Maxillofac Radiol 2002; 32 : 1-10)

Bowers(Actinidia arguta planch) grow widely in the mountains of Korea. This deciduous vine is now considered worth while to exploit as an outstanding edible landscape plant. The present study was carried out to find out the suitable propagation method of bowers For this experiment, cuttings were taken from the one-year-old stem. Rooting beds in a green house were filled with vermiculite and installed with the electric wires for heating under the beds. Rooting bed were closed with polyethylene film to maintain temperature and humidity. The results obtained are summarized as follows. The rooting percentage and rootlet number of male plant are higher than that of female plant. The male and female plants cuttings tended to have the largest root system in the 20±2℃ cutting bed. Cuttings treated with IBA 500ppm 30 secdip rooted better and larger root systems than other treatments. The rooting percentage, length of root and rootlet number in the 20±2℃ bed temperature was higher than those in the 15±2℃.

Digital signal processing mainly needs high speed arithmetic operations in real time. Therefore in order to process signals at high speed, the DSP with special hardware structures including multiplier, barrel shifter, and junction table etc. has appeared. In this paper, we designed function block of 16-bit fixed-point DSP core with RISC structure. Internal structure of DSP core is designed with each function block. Multiplier, ALU, Barrel Shifter of data part and Register part are programed in VHDL. Especially, designed adder which is one of multiplier's composition elements showed more progressive result than conventional CMOS adder and CPL adder about delay time and poser consumption. Timing diagram of MAC struction for design of control signal block is manufactured and implemented with ASM(Algorithmic State Machine), ASM chart is synthesized logically and then state-machine of MAC instruction is based on the results obtained

Purpose : The purpose of the experiment was to evaluating the diagnostic ability of dental caries detection using digital subtraction in the artificial caries activity model. Materials and Methods : Digital radiographies of five teeth with 8 proximal surfaces were obtained by CCD sensor (Kodak RVG 6100 using a size #2). The digital radiographic images and subtraction images from artificial proximal caries were examined and interpreted. In this study, we proposed novel caries detection method which could diagnose the dental proximal caries from single digital radiographic image. Results : In artificial caries activity model, the range of lesional depth was 572-1,374 μm and the range of lesional area was 36.95-138.52mm². The lesional depth and the area were significantly increased with demineralization time (p<0.001). Furthermore, the proximal caries detection using digital subtraction radiography showed high detection rate compared to the proximal caries examination using simple digital radiograph. Conclusion : The results demonstrated that the digital subtraction radiography from single radiographic image of artificial caries was highly efficient in the detection of dental caries compared to the data from simple digital radiograph.

Purpose : The purpose of this study was to develop the radiographic technique for detecting the demineralization which is known as indication of dental caries. Materials and Methods : This technique was based on the comparing of multiple radiographs which was irradiated by multiple X-ray spectra. For the meaningful comparing, the multiple radiographs were reconstructed to the dosimetrically consistent images using a standard material. The difference of resulting images of same target with multiple spectra represents the difference of response of material as regards the spectra. Results : We have found about 10% of demineralization of dental hard tissues particularly in the proximal region through the analyzing of differences. Conclusion : Most intriguing thing in this investigation was that the method to analyze difference shows us to an anatomic structure of dental hard tissues even if absolute values of optical density were excluded during the procedures.
