Background: Woori-Heukdon (KWH) is a Korean synthetic pig breed generated using Chookjin-Duroc (KCD), Chookjin-Chamdon (KCC), and their crossbreds. Currently, there is a severe lack of studies investigating the Korean breed populations including wild boars (KWB) throughout the genome. Objective: This study was performed to investigate the genetic characteristics of Korean pig populations at the genome-wide level. Methods: Using the SNP dataset derived from genotyped and downloaded datasets using the Illumina PorcineSNP60K BeadChip, we compared the genomes of 532 individuals derived from 23 pig breeds to assess the genetic diversity, inbreeding coefficient, genetic differentiation, and population structure. Results: KWB showed the lowest average expected heterozygosity (HE = 0.1904), while KWH showed the highest genetic diversity (HE = 0.02859) among Korean populations. We verified that the genetic composition of KWH, showing USD of 74.8% and KCC of 25.2% in ADMIXTURE analysis. In population structure analyses, KCC was consistently shown to be separated from other pig populations. In addition, we observed gene flow from Western pigs to a part of Chinese populations. Conclusion: This study showed that Korean native pigs, KCC have genetic differences in comparison with Chinese and Western pigs; despite some historical records and recent genetic studies, we could not find any clear evidence that KCC was significantly influenced by Chinese or Western breeds in this study. We also verified the theoretical genomic composition of KWH at the molecular level in structure analyses. To our knowledge, this is the first genomic study to investigate the genomic characteristics of KWH and KCC.

Endotracheal intubation has been used widely for the maintenance of airway in the emergency patient and CPR in the acute airway obstruction patient and to treat respiratory insufficiency. Endotracheal intubation has many advantages but it may cause several complications which rate about 4% of endotracheal intubation patient. Among these complications, laryngeal granuloma is a relatively rare complication arising about 1 case per 10,000∼20,000 cases. Authors report a case of laryngeal granuloma which developed after endotracheal intubation required during emergency treatment. Case: A 55-year old female patient visited Chosun University Hospital Emergency Room complaining of dyspnea, cyanosis and sweating on Feb. 8th 1995. According to past history, she had a little obesity, dyspnea on exercise and mild hypertension. At arrival, blood pressure was 240/110mmHg, pulse rate 150 rates/min, respiratory rate 12/min, body temperature 36.5℃ and cyanosis with sweating on whole body was observed. And the mental state was semicoma. At 5 minutes after arrival, sudden respiratory arrest developed and immediate endotracheal intubation which emergency treatment was performed it was difficult to intubate endotracheally due to short neck and obesity. At 1 hour after arrival, general condition of the patient recovered well and extubation was done. The patient was transferred to internal medicine department and discharged after 12 days of medical treatment. At 2 months after discharge, the patient felt a progressive hoarseness and foreign body sensation of larynx. She was diagnosed as laryngeal granuloma at ENT department of Chosun University. She underwent the surgical operation and discharged in good health after 7 days of admission.

Locoregional recurrence is the most common type of recurrence in surgical operation of gastric adenocarcinoma, and peritoneal dissemination is one of the most difficult problems in advanced gastric adenocarcinoma treatment. Because the peritoneal cavity is the most common site of the first recurrence after gastric cancer resection, intraperitoneal chemotherpy seems a logical choice for cancer chemotherapy. The Mitomycin C(MMC) adsorbed by the activated charcoal particles(CH) is relatively released when the drug concentration surrounding the carbon particles becomes low in the peritoneum of the peritoneal cavity. For the intraperitoneal chemotherapy on the advanced gastric adenocarcnoma, mitomycin C adsorbed on activated carbon particles was administered in the peritoneal cavity just before abdominal wall closure. The closed drainage tubes were inserted in the peritoneal cavity and clamped for tuo hours after completion of operation. MMC concentrations were serially measured in peritoneal fluid, plasma and urine at 2hour, 48 hour, 72 hour and 168 hour following its administration in order to study the efficacy of the MMC-CH as a drug delivery system. There were minimal toxicities in born marrow, liver, and gastrointestinal system after intraperitoneal MMC-CH administration. The data of this study suggested that MMC-CH may have a somewhat more beneficial effect than surgery alone when administered in optimal dose and schedules, but the MMC concentration of the peritoneal fluid was not sufficient to eradicate remnant cancer cells, and effective duration of maintenance was only below 24 hours in the peritoneal fluid and plasma.

The authors examined human immunity indicators such as CD4, CD8, Natural Killer(NK) cell, IgG, IgA, and IgM, and heavy metals such as Pb, Cr, Cd to evaluate the health hazard of welders. We selected total 126 male subjects, 60 welders who had more than 5 year working history as an exposure group, and 66 office workers and medical college students as a control group. This immunity evaluation approach is the first newly designed study that has never been tried in past studies on welder's heath evaluation. And the results were as follows. 1. Total lymphocyte count of peripheral blood was significantly higher in welder group, 2,615±650 ea/㎕ compared with 2,368±681 ea/㎕ in control group(p>0.05). 2. The proportion of CD4, CD8, NK cell in welder group was 37.5±9.4%, 24.0±8.8%, and 21.0±9.5%, respectively, and 35.5±6.5%, 25.0±6.9%, and 19.6±8.8% in control group. CD4 and NK cell were slightly higher, and CD8 was slightly lower in welder group. but there was no statistical significance between two groups(p≥0.05). 3. IgG, IgA, and IgM in welder group were 15.9㎎/㎗, 2.7㎎/㎗ and 1.5㎎/㎗, respectively, and 15.6㎎/㎗, 2.9㎎/㎗ and 1.7㎎/㎗ in control group. There was no statistical significance between two groups(p≥0.05). 4. Blood lead, cadmium and chromium concentrations were 4.2±1.8㎍/㎗, 0.4±0.38㎍/㎗, 1.2±0.6㎍/㎗ in welder group and 3.2±1.7㎍/㎗, 0.44±0.29㎍/㎗, 1.1±0.6㎍/㎗ in control group, respectively, and these value were within normal ranges.

To investigate the effects of cardiovascular risk factors on hearing loss, hearing threshold and cardiovascular risk factors such as blood pressure, hematologic values, and serum lipid levels of 3,827 persons who visited the Health Center of a University Hospital in Kumi for health examination from January 1, 1995 to July 31, 1997 were analysed. The results were summarized as follows; 1. Hearing threshold was shifted highly in both sex groups with age increased. Smoking did not influence increase of hearing loss, but drinking alcohol amount increased the hearing threshold when sex was adjusted. The most highly increased hearing threshold showed among farmers group, but next was blue collars group. Hearing threshold increasing basis with BMI increased. 2. Systolic and diastolic blood pressure and hematocrit value increased the hearing threshold in both sex groups, but hemoglobin value did not related to the hearing threshold. 3. Total cholesterol, LDL-cholesterol, triglyceride, and atherosclerosis index were significantly increased with the grade of hearing loss increased, when age was adjusted. 4. In the logistic regression analysis, the atherosclerosis index, age, and hematocrit value revealed risk factors which contributed in that orders, though the values were small they showed statistical significaces, but the risks were lowered when hemoglobin values increased, in both sex groups. Consequently, hyperlipidemia was significantly related to the hearing loss when age was adjusted.

The objectives of this paper aims at investigating the characteristics of image which appears by schema during the concept design process of an architect. The image is an efficient tool for the design process as well as a useful medium for creative design idea. It affects design process to interpretate given conditions and helps to shape the initial form at the elementary stage of design. The image is able to be translated as the expression of an architect's schema. Architects will create the final form of the design from this schematic images including his own design language. This paper searches the images affected on architect's projects, and verifies the influence of schema on the common images, and analyses the relationship between schema and image.

The most important thing of the corporate color can be a visual effect. In recent, recognizing the importance of corporate identity, many companies are introducing a new CI contending with others. Accordingly the consumers select the importance of color first in recognizing the image of corporate. The purpose of this study is to describe the relations of corporate color and form affecting in case of selecting corporate color, the meaning of colors, the colors being affected in fashion, the corporate color of two tones, special color and the regional differences of colors. So it is to represent a good direction in case of selecting corporate color in many companies. This study will also suggest the direction of analytical method of corporate color applying image scale of NCD, and will predict and analyze the following tendency of corporate color.

Formaldehyde induces not only irritation symptoms of eyes and respiratory tract but hypersensitivity reactions, such as contact dermatitis, allergic rhinitis, and asthma. To estimate the levels of exposure to formaldehyde during cadaver dissection in anatomy laboratory and to investigate the prevalence rates of irritation symptoms, allergic rhinitis and bronchial asthma, air concentrations of formaldehyde within cadaver dissection room were measured, and self-administrative questionnaire and enzyme linked immunosorbent assay(ELISA) were performed upon medical(n=182) and premedical students(n=69). For measurement of air formaldehyde level, chromotropic acid method(NIOSH method 3500) was used. Formaldehyde was conjugated to human serum albumin, and used as antigen in ELISA after identification of conjugation with immunoelectrophoresis. Prevailing symptoms during cadaver dissection were soreness of eyes or throat(92.9%), lacrimation(74.3%), rhinorrhea(49.7%), and sneezing(32.2%). Mean titers of IgE and IgG antibodies specific to formaldehyde-human serum albumin conjugate(F-HSA) of medical students were higher than those of premedical students. However, there was no case whose titers of anti-F-HSA antibody were higher than the twice of those of anti-HSA antibody or higher than the twice of the mean titers of premedical students. These results suggest that medical students were exposed to relatively high concentration of formaldehyde, but few asthma or allergic rhinitis were induced by formaldehyde exposure during cadaver dissection practice.
