High spatial resolution ultrasonic imaging is necessary in several fields of investigation, in order to permit greater precision of clinical diagnosis in the dermatology, ophthalmology etc. We present a B-mode scan system using sector scanning probe of 20MHz center frequency. This developed system allow the high resolution image of 250${\mu}m$ in lateral and 80${\mu}m$ in axial, which of display the size of a $5mm {\times} 5mm$ image with 20 frames/sec. We have shown the images of various structural elements of the human skin and of the nail. We have compared the skin images obtained for each of the different age and we have shown in a general with the age, the atrophy of the skin thickness and the appearance of the abnormal hypoechogene band under epidermis (named SENEB : Sub Epidermal Non Echogene Band).

In this study, to improve the quality of school lunch in local colleges, we conducted a survey on students who attend 2 year colleges in Jeju region. With its own unique regional characteristics and the change of its school lunch program from direct management to consignment, there were some questions about how each factor in school lunch program affects on students' satisfaction with it and we tried to present helpful data to improve school lunch programs in each region. The survey took place from May 5 to May 10, 2005 covering the colleges only in Jeju region. There were 200 sets of questionnaires issued and distributed to the students who are currently using school lunch programs. Only 168 sets were retrieved and processed statistically. 2 sets out of 168 questionnaires had to be thrown away because there were wrong entries of some questions, which made overall retrieving rate 83%. In this study, SPSS 10.0 , one of the statistical package programs, was used as an analyzing tool to make Frequency Analysis. To verify credibility, Cronbach's Alpha Element Analysis was done and T-test and ANOVA was also made. After Recurrence Analysis for elements of satisfaction regarding main factors that is considered to be important to customers, we found that importance of following factors: appearance of food, incongruity between main and side dishes, availability of seasonal food, availability of preferred menu, absence of food stock, waiting time, accessibility of food counters, space between chairs, presentation of a menu, food tray's shape, and color of food trays. The importance of those showed high but satisfaction with the same factors was low. So the primary improvement on these factors should be made to increase satisfaction. Finally we concluded that in large extent, importance of each factor definitely affects on students' satisfaction.

Hemolytic disease in a newborn that causes early jaundice is common. It is often due to the Rh (D) and ABO incompatibility, but rarely due to unexpected antibodies. Among these unexpected antibodies, the anti-$Di^a$Dia antibody rarely occurs. The anti-$Di^a$ antibody was observed in the serum and red-cell eluate of an infant, and in the serum of his mother. The frequency of the appearance of the $Di^a$ antigen in the Korean population is estimated to be 6.4-14.5%. This paper reports a case of hemolytic disease in a newborn associated with the anti-$Di^a$ antibody. A full-term male infant was transferred to the authors' hospital due to hyperbilirubinemia the day after his birth. The laboratory data indicated a hemoglobin value of 11.6 g/dL, a reticulocyte count of 10.6%, a total bilirubin count of 14.4 mg/dL, a direct bilirubin count of 0.6 mg/dL, and a positive result in the direct Coombs' test. Due to the identification of an irregular antibody from the maternal serum, an anti-$Di^a$ antibody was detected, which was also found in the eluate made from the infant's blood. The infant had been treated with phototherapy and intravenous immunoglobulin since the second day after his birth and was discharged due to an improved condition without exchange transfusion. Therefore, in cases of iso-immune hemolytic disease in a newborn within 24 hours from birth who had a negative result in an antibody screening test, the conduct of an anti-$Di^a$ antibody identification test is recommended due to the suspicion of an anti-$Di^a$ antigen, followed by early administration of intravenous immunoglobulin.

The frequency and distribution of lymphoma caused by bovine leukemia virus (BLV) infection in various organs were investigated. Lymphoma samples were obtained from slaughtered cattle or from cattle submitted to the National Veterinary Research and Quarantine Service, Korea. Thirty female Holstein-Friesian dairy cattle aged over three years with the BLV-associated lymphoma were studied. None of the Korean native cattle (Hanwoo) had lymphoma in this study however. Lymphoma tissues were gray to pink in color, soft in consistency, and bulged from the cut surface. In advanced lymphoma tissues, there was great variety in the appearance of involved structures due to hemorrhage, necrosis, and/or calcification. Neoplastic tissues were observed in lymph nodes in all lymphoma cases. Intestine (96.4%), heart (88.9%), stomach (73.1%), and diaphragm (62.5%) were frequently involved with lymphoma. However, there was no lymphoma detected in liver. Large neoplastic masses, sometimes reaching the size of over 20 cm, were found in the abdominal cavities. It is suggested that metastasis of lymphomas occurs mainly via lymph based on gross observations; neoplasia may have been initiated in the serosal surface of the lung, heart, peritoneum, and numerous hollow organs in the abdominal cavity. Also many organs in the abdominal and thoracic cavity were affected by neoplastic tissues simultaneously. Characteristics observed in this study could be used as criteria to differentiate BLV-associated lymphoma from other nodular lesions in the slaughterhouse and as fundamental data to make clear the mechanism of metastasis or pathogenesis of EBL.

Background: There is strong evidence that delayed diagnosis of breast cancer is associated with poor survival. Our objectives were to determine the frequency of breast cancer patients with delayed presentation, the reasons of delay and its association with different socio-demographic variables in our North Pakistan setting. Materials and Methods: We interviewed 315 histologically confirmed breast cancer patients. Delay was defined as more than 3 months from appearance of symptoms to consultation with a doctor. Questions were asked from each patient which could reflect their understanding about the disease and which could be the likely reasons for their delayed presentation. Results: 39.0 % (n=123) of patients presented late and out of those, 40.7% wasted time using alternative medicines; 25.2 % did not having enough resources; 17.1 % presented late due to painless lump; 10.6% felt shyness and 6.5% presented late due to other reasons. Higher age, negative family history, < 8 school years of education and low to middle socio-economic status were significantly associated with delayed presentation (p< 0.05). Education and socioeconomic status were two independent variables related to the delayed presentation after adjustment for others (OR of 2.26, 2.29 and 95%CI was 1.25-4.10, 1.06-4.94 respectively). Conclusions: Significant numbers of women with breast cancer in North Pakistan experience presentation delay due to their misconceptions about the disease. Coordinated efforts with public health departments are needed to educate the focused groups and removing the barriers identified in the study. Long term impact will be reduced overall burden of the disease in the region.

Objectives: This study investigated the perception on the effects of malocclusion on employment, and aimed to provide information to those who are seeking employment. Methods: The study examined 306 subjects aged 19 to 39 in Seoul and Gyeonggi-do during the month of December, 2016. The data obtained were analyzed using frequency analysis, t-test, one-way ANOVA, chi-square test and multiple regression analysis among others. Results: The most important factors in job success were education (35.9%), followed by appearance (23.8%), and major (22.1%). On whether there is a correlation between social life and malocclusion, 49.0% and 51.0% of the subjects answered 'Yes' and 'No', respectively. When the factors influencing the perception of the effects of malocclusion on employment were reviewed, it was found that for female(p<0.01) subjects, the perceived effect of malocclusion on life and on employment (p<.001), and the perceived effect of malocclusion on employment were lower in 20-24 year olds and 25-29 year - olds (p<0.01). Conclusions: Many people believe that malocclusion affects employment and that it is necessary to provide information on orthodontic treatment to those who are preparing for employment and ordinary. However, it is important to provide correct information about orthodontic treatments, including functional improvement, rather than simply focusing too much on aesthetic effects alone.
