It is said that we live in an age of technology. And indeed, science and technology do play key roles to our life of happiness, but they are equally central in all events that threaten it. Science and technology are the means we often turn to in seeking solutions to our problems, and in turn are often the apparent sources of new problems. Thus it is not surprising that they have two aspects at the same time. CCTV has been presented to us as a technical solution to security problems. With the help of CCTV, we can more effectively prevent, detect, and prosecute crimes. With the help of CCTV, both public and private spaces can be made more secure. But of course, CCTV also has a down side. The down side most prominently anticipated has been loss of privacy and proliferation of surveillance. It is largely this potential problem with CCTV that has been regulated against. It is said that one reason for imposing a limitation on individual privacy is the societal interest in the prevention of crime. Accordingly a balance between the need to prevent crime through the use of CCTV and the duty to respect the privacy interests of individual citizens is in need of redress. In other hand, two theories of socio-political philosophy may have provided useful ways of understanding the role of CCTV in contemporary society. Firstly, neo-Marxist frameworks, for instance, stress the use of CCTV to police existing unequal socioeconomic divisions within society and the dominance of particular forms of order based upon materialist agendas. Secondly, Foucauldian frameworks contend that Foucault's notion of panoptic surveillance underpinning (self) disciplinary society is an appropriate template for understanding CCTV in late-modern society. In order to find a new point of valance between security and privacy in the use of CCTV, the participation of each citizen in the discourse to make the new norm is necessary. And to prevent its political misuse, their surveillance, or check for the potential surveillance-power is required.

Purpose: We wanted to evaluate the results of surgical treatment for fracture of the scapular body. Materials and methods: The subjects of this study were seven patients with fracture of the scapular body and all these patients were managed surgically. We considered the operative indications as being 100% translation of the lateral border, or $25^{\circ}$ of angular deformity of the glenoid, or 1cm medialization or the variant of the double disruption of the superior scapular suspensory complex. There were five males and two females, and their ages ranged between 40 and 58 years (mean age: 49) with average follow up of 11 months (6~24 months). Two patients sustained multiple fractures of the ribs and spines. The surgical results were evaluated according to the subjective satisfaction, the UCLA score and the Korean shoulder score. Results: The mean UCLA score was 29 (17~33) and the mean Korean shoulder score was 86 (63~94). The self assessment for subjective satisfaction was 7.7 (4~9). There were two complications; one case of screw pull-out without the loss of the fracture fixation and the other case with screw penetration of the glenoid cavity. Conclusion: Surgical treatment may be effective for the management of severely displaced fracture of the scapular body in order to prevent the impairment of the shoulder function caused by the altered glenohumeral and scapulothoracic kinematics.

The purpose of this study is to investigate the stress and coping level as a result of dysmenorrhea which was experienced by girls. For the collection of data, the girls from the 1st to the 3rd grade in middle school in Seoul were selected through a random sampling technique. The survey was conducted from the 1st. to the 14th of June, 1991 by the use of questionnaires made after a pilot study. The final subjects for analysis were restricted to only those who had experienced me~arche, the number of which totaled 1,131. The stress, coping level, and other variables, were tested and analysed by descriptive statistics (eg, frequency, percentage, mean and standard deviation), t-test, ANOVA and Pearson's correlation coefficients. The obtained results are summarized as follows. 1. The chronological start for menarche was at a mean age of 13.1 The respondents who had experienced menarche numbered $70.9\%$ of the 1st grades and $96.2\%$ of the 2nd grades in middle school, otherwise the starting age for menarche was in the 4th grade in primary school. 2. Their menstrual cycle and period were longer than adult's one. The number of students studied who had experienced dysmenorrhea during their menstrual cycle were 860, and 650 of those revealed that their mothers or sisters had experienced similar problems. 3. The subjects who were late or head left early rather than being absent from school every menstruation cycle were more stressful. The results are thought to show that the girl's perception of dysmenorrhea seems to be more sensitive than adult's one. 4, A significant negative correlation was found between the perception of menstrual flow and strees level. It means that an increase in the stress of dysmenorrhea was associated with decreased menstrual bleeding. The degree of hypochondrical concern assessed by the girls was significantly correlated to stress and coping level. When the girls perceived high stress as a result of dysmenorrhea, they worried about their physical health more. The above results lead us to the suggestion that the starting point of early education with a school program is appropriate for the 4th grade in primary school. Especially if the girls in middle school should be required to give the information about correct knowledge and sufficient self -care management of menstruation monthly, if this could be implemented the loss in school days among the students due to dysmenorrhea would be minimized with more ease.

Purpose: The bony mallet finger injury is generally managed by conservative treatments, but operative treatments are needed especially when the fractures involve above 30% of articular surface or distal phalanx is accompanied by subluxation in the volar side. This is the reason they often result in chronic instability, articular subluxation and unsatisfactory cosmetic. In this report, We describe new method using the hook plate as an operative treatment of Mallet finger deformity. Methods: Among 13 patients with Mallet finger deformity who came from February 2006 to February 2008, six patient were included in surgical indication. Under local anesthesia, H or Y type incision was made at the DIP joint area. After the DIP joint extension, the hook plate was put on the fracture line, and one self tapping screw was used for fixation. 2 hole plate which was one of the holes in 1.5 mm diameter was cut in almost half and bended through approximately $100^{\circ}$. Results: In all six cases which applied the hook plate, complications such as loss of reduction or nail deformity were not seen. In only one patient, hook pate was removed due to inflammatory reaction after surgery. At 2 weeks after operation, active motion of DIP joint was performed. The result was satisfactory not only cosmetically but also functionally. At 6 weeks after operation, the range of motion of DIP joint was average $64^{\circ}$. Conclusion: The purpose of the operative treatment for mallet finger deformity using the hook plate is to provide anatomical reduction with rigid fixation and to prevent contracture at the DIP joint. While other operations take 6 weeks, the operation using the hook plate begins an active motion at 2 weeks after operation. Complication rate was low and the method is rather simple. Thus, the operation using the hook plate is recommended as a good alternative method of the mallet finger deformity treatment.

The authors studied depression, using Zung's self-rating Depression Scale(SDS), in the subjects of 65 males and 231 females at the homes for the aged in Taegu and Kyong-buk areas. The authors collected the data of SDS during the period from June to August, 1986, and applied ANOVA and t-test on the depression scores in order to compare them between various psychosocial factors and sexes. The results could be summarized as follows: There was significantly difference in the mean average of total depression scores between the two groups: elderly males scored $38.80{\pm}11.92$, elderly females scored $43.21{\pm}14.33$(P<0.05). The depression scores in the items of hopelessness, personal devaluation, weight loss, emptiness and confusion were relatively higher than the scores in the other items in both groups. Nine elderly males(16%) showed seriously high depression scores of 50 and over, while fourth-seven elderly females(33%) showed the same scores. Among these psychosocial factors, age, birth place, and growing place are significantly related to higher depression scores in both groups.

BACKGROUND: Ammonia gas emitted from nitrogen fertilizers applied in agricultural land is an environmental pollutant that catalyzes the formation of fine particulate matter (PM2.5). A significant portion (12-18%) of nitrogen fertilizer input for crop cultivation is emitted to the atmosphere as ammonia gas, a loss form of nitrogen fertilizer in agricultural land. The widely practiced method for fertilizer use in agricultural fields involves spraying the fertilizers on the surface of farmlands and mixing those with the soils through such means as rotary work. To test the potential reduction of ammonia emission by nitrogen fertilizers from the soil surface, we have added N, P, and K at 2 g each to the glass greenhouse soil, and the ammonia emission was analyzed. METHODS AND RESULTS: The treatment consisted of non-fertilization, surface spray (conventional fertilization), and soil depth spray at 10, 15, 20, 25, and 30 cm. Ammonia was collected using a self-manufactured vertical wind tunnel chamber, and it was quantified by the indophenol-blue method. As a result of analyzing ammonia emission after fertilizer treatments by soil depth, ammonia was emitted by the surface spray treatment immediately after spraying the fertilizer in the paddy soil, with no ammonia emission occurring at a soil depth of 10 cm to 30 cm. In the upland soil, ammonia was emitted by the surface spray treatment after 2 days of treatment, and there was no ammonia emission at a soil depth of 15 cm to 30 cm. Lettuce and Chinese cabbage treated with fertilizer at depths of 20 cm and 30 cm showed increases of fresh weight and nutrient and potassium contents. CONCLUSION(S): In conclusion, rather than the current fertilization method of spraying and mixing the fertilizers on the soil surface, deep placement of the nitrogen fertilizer in the soil at 10 cm or more in paddy fields and 15 cm or more in upland fields was considered as a better fertilization method to reduce ammonia emission.

The effect of nanoclay (Cloisite 20A) on the self-adhesion behavior of uncured brominated-isobutylene-isoprene rubber (BIIR) has been studied. The dispersion state of nanoclay into the rubber matrix was examined by SEM, TEM and XRD analysis. The thermal degradation behavior of the filled and unfilled samples was examined by TGA and improvement in the thermal stability of the nanocomposites occurred based on the weight loss (%) measurements. Also, addition of nanoclay enhanced the cohesive strength of the material by reinforcement action thereby reducing the degree of molecular diffusion across the interface of butyl rubber. However, the average depth of penetration of the inter-diffused chains was still adequate to form entanglement on either side of the interface, and thus offered greater resistance to peeling, resulting in high tack strength measurements. The improvement in tack strength was only achieved at critical nanoclay loading above 8 phr. Contact angle measurement was also made to examine the surface characteristics. There was no significant interfacial property change by employing the nanoclay.

Objectives : This study was performed to investigate the distribution of apolipoproteins A-I and B among Korean employees and their partners. Methods : The study population consisted of 7,633 men and women (4,578 men and 3,054 women) residing in Seoul and Kyung-gee Do, with an average age of $43.5{\pm}8.3$ years. Blood samples were collected following at least 12 hours of fasting. Apolipoproteins A-I and B were measured using a Behring Nephelometer analyzer. The body mass index (BMI) for each participant was calculated as weight (kg) divided by height squared $(m^2)$. Information on health-related behaviors such as exercise, alcohol intake, and smoking habits was collected through self-administrated questionnaires. Results : The mean concentrations of Apo A-I were $132.6{\pm}22.3mg/dL$ and $142.9{\pm}24.8mg/dL$ in the men and women, respectively. The concentration of Apo A-I increased significantly across all age categories of men. The mean concentrations of Apo B were $101.7{\pm}23.2mg/dL$ and $87.8{\pm}23.5mg/dL$ in the men and women, respectively, and Apo B increased significantly across all age categories for both the men and women. Exercise and BMI were major determinants for Apo A-I and B levels. The 10th percentile of Apo A-I concentration was 109 mg/dL in the men and 113 mg/dL in the women, and the 90th percentile of Apo B concentration was 131 mg/dL in the men and 118 mg/dL women. Conclusions : For the prevention of coronary artery disease, we recommend that for individuals in the 10th percentile of concentration for Apo A-I and the 90th percentile of concentration for Apo B, active preventive interventions such as weight loss and exercise should be taken. This study, within its limitations, may be useful for evaluating apolipoprotein A-I and B concentrations in Korean adults.

The purpose of this paper was to identify the performance of health promoting lifestyles and health perception over 18 years old women living Wonju city so that the results will be based for setting up women's health nursing center. The subjects were 1080 women selected by stratified and purposive sampling. The data were collected by self reporting questionnaire and interview from May to June, 1998. Data were analyzed by SPSS win program. The results were as follows : 1. The range of age was 18-84 years, The proportion according to women's lifecycle was premarital group 20.0%, delivery and rearing group 49.9%, over middle aged-elderly group 29.8%. 2. The mean menarchial age was 15.2 and menopausal age was 48. Mean frequenices of pregnancy is 2.4 and artificical abortion rate is 36.4%. Primary cause of abortion was unwanted babies 42.8%. The practice rate of family planning was 79.4% and permanent sterilization rate was 37.6%. 3. Fatigue was predominated problem in target population. Depression and headache was predominated in premarital group, headache and nervous felling in delivery and rearing group, arthritis and loss of memory in over middle aged-elderly group. 4. Only 13.7% of the target population make some efforts for their health in compare to 85.9% have attention for their health. Perception of unhealthy rate was 9.1% in premarital group, 24.8% in delivery and rearing group, 30.1% in middle aged-elderly group. 5. The average score of the HPLP(Health Promoting Lifestyle Profile) was 2.41. The variable with the highest degree of performance was interpersonal relationship, whereas the one with the lowest degree was the professional health maintenance. The significant difference was found in HPLP according to age, residential area, marital status, educational level, income level. 6. Majority(95.1%) of the target population agreed on necessity for women's health nursing center. Proper location area was presented to women's center and public health center. The priority for health education program was proper diet, family health, stress management, and exercise. In conclusion, we should prepare the education program for women's health according to women's lifecycle, because health perception, HPLP, and education program needed was differentiated in women's lifecycle. Also we suggest that women's health nursing center based community was needed for proper management of women's health.

Efficient gene transfer into hematopoietic stem cells is a great tool for gene therapy of hematopoietic disease. Retrovirus have been extensively used for gene delivery and gene therapy. However, current in vitro gene transfer has some obstacles suck as induction of differentiation loss of self-renewal capacity, and down-regulation of homing efficiency for in vitro hematopoietic stem cells transplantation. To overcome these problems, we developed efficient in vitro retroviral transfer technique by direct intra-bone marrow injection (IBM). We identified effective retrovirus gene transfer in bone marrow hematopoietic cells in vitro. Two weeks after retrovirus transfer via IBM injection, we observed stable EGFP gene expression in bone marrow, lymph node, spleen, and liver cells. In addition, $6.4{\pm}2.7%$ of hematopoietic stem/progenitor cells were expressed EGFP transgene from flow cytometry analysis. Our results demonstrate that in vitro retrovirus gene transfer via IBM injection can provide a viable alternative to current or moo gene transfer approach.
