As computer Programs for cephalometric analysis were developed in diagnosis & treatment planning, digital imaging of film-based cephalograms came to be needed. When a digital camera is used, a problem encountered the image distortion produced according to the focal length, which causes errors in indentifying landmarks. In addition, changes in the image size and compression ratio will inevitably produce a low quality image, causing errors in identifying landmarks. Hence. we have found the focal length producing the least image distortion when digital imaging the film-based cephalograms and the minimal digital camera setting which helps to identify the correct landmarks using the COOLPIX4500 digital camera (Nikon, Japan). The results were as follows The image distortion was minimized at a focal length of 16.4mm (79.4mm when converted into a 35mm film camera) when digital imaging the film-based cephalograms. When wide imaging, with a focal length of under IS.4mm, barrel distortion was found and when tole imaging. with a focal length of over 15.4mm pincushion distortion was found. The minimal digital camera setting was $2272{\times}1704$ pixel at normal (1/8) compression from which we can identify the correct landmarks at the same level as tracing the film-based cephalograms manually. As a result. when digital imaging the film-based cephalograms, using a COOLPIX4500 digital camera (Nikon, Japan), the focal length should be 16.4mm the pixel image size over $2272{\times}1704$, and the compression ratio over normal (1/8).

Objective: Oxidative stress plays a key role in the pathogenesis of male infertility. But, the adverse effects of oxidative biomarkers on sperm quality remain unclear. This study aimed to investigate the levels of nitric oxide (NO), 8-hydroxydesoxyguanosine (8-OHdG), and total antioxidant capacity (TAC) oxidative biomarkers in seminal plasma and their relationship with sperm parameters. Methods: A total of 77 volunteers participated in the study, including fertile (n = 40) and infertile men (n = 37). NO, 8-OHdG, and TAC levels were measured using the ferric reducing ability of plasma, Griess reagent method and an enzyme-linked immunosorbent assay kit, respectively. Results: The mean values of sperm parameters in the infertile group were significantly lower than those in the fertile group (p< 0.001). The mean 8-OHdG in the seminal plasma of infertile men was significantly higher (p= 0.013) than those of controls, while the mean TAC was significantly lower (p= 0.046). There was no significant difference in NO level between the two groups. The elevated seminal 8-OHdG levels were negatively correlated with semen volume, total sperm counts and morphology (p< 0.001, p= 0.001 and p= 0.052, respectively). NO levels were negatively correlated with semen volume, total sperm counts and morphology (p= 0.014, p= 0.020 and p= 0.060, respectively). Positive correlations between TAC and both sperm count and morphology (p= 0.043 and p= 0.025, respectively) were also found. Conclusion: These results suggested that increased levels of NO and 8-OHdG in seminal plasma could have a negative effect on sperm function by inducing damage to the sperm DNA hence their fertility potentials. Therefore, these biomarkers can be useful in the diagnosis and treatment of male infertility.

This study was performed to analyze the patient's experience during the progress of disease in the patients with osteoarthritis, who are taken the replacement surgery of knee Joint. The examine was consisted of five patients with osteoarthritis, who are taken the replacement surgery of knee joint from Dec. 4. 1995 to May, 20, 1996 at C university hospital. After hospitalization, the physical and psycho-logical status of the patients during preoperation, postoperation and discharge was examined. The data were examined according to the ethnographic method. The results are as follows. The patients experienced the periods of embarrasment, conflict, before surgery suffering, acceptance period after surgery. In the embarrasment period, the patients take a multiple medication therapy including hospital treatment, oriental medication and folk medication to ameliorate joint pain after first diagnosis on arthritis. The embarrasment period includes compulsive drug medication, oriental medication, folk medication, trouble some, sadness and survey of hospitals. In the conflict period, the patients consider the operation of knee because of working difficulty and severe Joint Pain, while they feel anxiety about the surgery. They condemn their physical situations. They have the conflict and anxiety on surgical operation. they consider the quality of life. They hope the surgery makes patients to improve walking ability. This period includes self-condemned, sorry, tiresomeness, expectation, worrisomeness, anxiety and hesitance. In the suffering period, the patients experience post operation physical discomfort after the total knee replacement. They do physical exercise, including extension and straight leg raising to maintain walking ability, while they endure to wait approximately 6 months for normal walking movements and they are also unstable to environmental people's sight. This period includes postoperative pain, continuous discomfort, inability and communication difficulty to other's people. In the acceptance period, the patients consider longerity of artificial Joint and also endure mild remaining joint pain. Some of them have religions for their wellbeing of life. This period include a self-protesting policy, abandonment, self-consolation, dependence on religions. According to the result from this study I suggested these shown below. 1) After replacement surgery of knee joint, continuous investigation on outcome patient is necessary. 2) It is also necessary to analyze on patient's experiences, who are taken the replacement surgery of hip Joint. 3) Study on disease experiences of patients with rhematoid arthritis, who take drug medication and physical therapy alone without surgery, is necessary. 4) Investigation on patient's favorable folk medication may be helpful to analyze disease experience of patients with osteoarthritis.

In the past, a patient went to the room where an ultrasound image diagnosis device was set, and then he or she was examined by a doctor. However, currently a doctor can go and examine the patient with a handheld ultrasound device who stays in a room. However, it was implemented with only fundamental functions, and can not meet the high performance required by the focusing algorithm of ultrasound beam which determines the quality of ultrasound image. In addition, low energy consumption was satisfied for the mobile ultrasound device. To satisfy these requirements, this paper proposes a high-performance and low-power single instruction, multiple data (SIMD) based multi-core processor that supports a representative beamforming algorithm out of several focusing methods of mobile ultrasound image signals. The proposed SIMD multi-core processor, which consists of 16 processing elements (PEs), satisfies the high-performance required by the beamforming algorithm by exploiting considerable data-level parallelism inherent in the echo image data of ultrasound. Experimental results showed that the proposed multi-core processor outperforms a commercial high-performance processor, TI DSP C6416, in terms of execution time (15.8 times better), energy efficiency (6.9 times better), and area efficiency (10 times better).

The breast cancer has the highest occurrence rate among the female cancers, and as the living style changes, the occurrence is increasing gradually. For the breast cancer test among women, who comprises up to 50% of the total population, the mammography is mainly used as the screening test, and the accuracy control is the most important aspect of the testing. Therefore this research divided the northern part of Kyeongsangbuk-do into 4 regions and investigated the accordance ratio of examination field and light examination field, the total focus using the optical density and compression rate, and the overall maintenance of mammography within the regions. The equipments of 11 hospitals were investigated, and the 7 hospitals passed the standard level of the accordance ratio of examination field. 6 hospitals passed the standard optical density, and 7 hospitals had the passing performance in the compression rate. Fibers, group of specks, and masses within the Mammographic Accreditation Phantom scored 10, being within the standard range. However, only 3 hospitals were equipped with private development processor and illumination. The result reflects the fact that the image quality of breast is not correctly being maintained. Moreover, only 27.27% satisfied all the three categories of compression fitting, accordance ratio of examination field, and phantom image evaluation at the same time. The accuracy control must be maintained more precisely for the accurate diagnosis of breast cancer.

The subjects were recruited women from Wonju city 18 years or older. 1. The results showed that about 50% of the women were satisfied with their lives as women, 23% of the sample felt there was a need for a women's health care center. The mean number of health problems was 3.1 and the prevalence rate, 44.4%. 2. We developed on educational program according to group differences related to health problems, diagnosis of disease, variables influencing health promotion behavior, and programs which each group wanted. Also we stressed self-efficacy and self-help group for the management of individual health to all groups. 3. The diagnoses of diseases that were experienced premarital over the past year were gastritis, bronchitis, spinal disk, and fracture, for the childbearing/rearing group, gastritis, vaginitis and cervicitis, cervical cancer and cystitis and nephritis and arthritis and for the middle-aged/elderly group arthritis, gastritis, vaginitis and cervicitis, and spinal disk. Of the sample 30.5% did not have a health exam in the past year, and only 10% of the premarital group, 12.5% of the childbearing/child-rearing group, and 18.3% of the middle aged-elderly group were concerned about their health and did something for their health. 4. The average score on the HPLP was 2.41. the HPLP was scores according to group were found to have significant differences. self-efficacy, family functions, health attention and were considered important variables in the premarital group, in the childbearing/child-rearing group self-efficacy, family functions, internal locus of control, health attention, and health perception and power others locus of control and then for the middle aged-elderly group self-efficacy, health attention, internal locus of control, family functions and health perception. 5. There are a few educational programs in the city provided by the Wonju Health Center and by community health nurse practitioners. The premarital group requested the educational programs on diet, health exercise, family health and stress management. Also the childbearing/child-rearing group wanted programs on diet, family health, stress management, and health exercise, and the middle-aged/elderly group wanted that of family health, diet, climacteric changes stress management and health exercise. The program suggested that this program should be applied to women in the community to insure adequate management of women's health. Follow-up research with PROCEED is needed to analyze health outcomes, also, a women's health nursing specialist system is required to develop health promotion, and improve the quality of life for women.

In this era of big data, a variety of government organizations are trying to create new added value via Information Integration. Therefore, several projects related to government agencies' information sharing have activated system connection/integration. The risk factors of system operation, however, have increased as the volume of Information Integration System grows. The interference in information sharing is predicted to affect the operation of the agencies, and the issue will grow even worse with massive impact on civil society when the agency operation is interrupted due to system failures in terms of infrastructure, software, data quality, and security. Diverse studies related to the maintenance of Information System have been conducted, but there is currently no evaluation framework for the operational system of Information Integration between various government agencies. In this respect, this study distinguishes each of the Information System components, Data, IT, People, Process, systematizes with Plan-Do-See, and finally presents a maturity model for Information Integration. Nine derived processes were analyzed through interview and questionnaires from Information Integration System officials, further suggesting maturity stage applying CMMI. This model allows diagnosis of the maturity level of an Information Integration System, and is expected to be utilized as resource for improving organizational processes.
