This study was planned in order to investigate coal miners' recognition and attitude toward pneumoconiosis, and its relationship with related behavior for prevention of pneumoconiosis. Study object was coal miners in Kangneung area, sampled by multistage random proportional sampling, Sample size was 13% of total coal miners in Kangneung area. The results were divided into three parts: (1) descriptive results presented percent distribution, (2) reclassification of knowledge, experiences, and attitude by factor analysis, (3) prediction of health behavior for prevention of pneumoconiosis by discriminant analysis. Knowledge, experiences, and attitude toward pneumoconiosis were classified into nine factors. Knowledge about pneumoconiosis were broken down to two factors and attitude to four factors, and valence, perceived severity were classified into each one factor. According to demographic, socioeconomic characteristics, and factors of knowledge, experiences, attitude about pneumoconiosis, about 62% of behavior of wearing respiratory protector was correctly discriminated. And by the same methods, about 81% of behavior of hospital visit at respiratory symptoms; cough, sputum, chest pain etc. was discriminated correctly.

2.A Clinical Study on 98 Cases of Purpura.
Korean Journal of Dermatology 1979;17(2):123-129
A clinica1 study was carried ou on the 98 cases of purpura who were admitted to the Han Gang Sung Shim Hospital during the period of 3 years from Sept., 1975 to Aug., 1978. The results were as follows: 1. The most common cause of purpura was allergic purpura (35.7%). 2. The highest incidence was under 10 years of age group(63.3%), and males were more frequently affected tban fomal with the ratio of 1.3: l. 3. The saonal incidence of purpura was high during the period of 5 months fror Jan. to Klay. Especially in the allergic purpura high incidence was seen in April, May and October. 4. The preclilection site of purpura was on the lower extremities (87.5%) Especially in allergic purpura, the purpura lesions were occured on the lower extremities in all cases. 5, Platelet count in allergic purpura was normal, and that of L.T.P., leukemia, menigococcemia, aplastic anemia and sepsis was decreased in mostly all cases. 6. Bleeding; time was normal in allergic purpura, hut prolonged in ahout 50% of otber diseases. Coagulation time was normal in all cases. 7. Occuit blood was positive in 40% of all cases. 8. Renal rnan!festations occured in 37 cases(37.8%). The most common among them was proteinuria(89.2%)

3.Biocontrol Effect of Gliocladium virens G1 and Soil Amendment on Astragal Stem Rot Caused by Rhizoctonia solani.
Mycobiology 2000;28(4):180-184
In order to find an environment-friendly method to suppress astragal stem rot caused by the isolates of Rhizoctonia solani AG 1 and AG 4, we tested an antagonistic fungus Gliocladium virens G1 was evaluated as a biocontrol agent and estimated inorganic compounds and organic materials were tested for their effect of the disease suppression. G. virens G1 effectively inhibited mycelial growth in a dual culture and caused mycelial lysis in the culture filtrate. No adverse effect was observed when examined for seed germination and seedling growth. Promoted seedling growth was observed with the seed treatment. Seeds of astragal plant were germinated higher in the sterile soil than the natural soil. Of 14 inorganics tested, alum, aluminum sulfate and calcium oxide significantly suppressed the mycelial growth and sclerotial germination. Milled pine bark and oak sawdust also suppressed the mycelial growth. Soil amended with 1% of G. virens G1 composted with pine bark (w/v) significantly controlled astragal stem rot in the glasshouse experiments.

4.Analysis of prognositic factors and long-term survival according to the pattern of lymph node metastasis in surgically resected N2 Non-Small cell lung cancer(NSCLC).
Tuberculosis and Respiratory Diseases 2000;49(4):474-485
BACKGROUND: Current studies on multimodal strategy for N2 non-small cell lung cancer are being high interest have drawn much attention. N2 lung cancer, however, is composed of is divided into several subgroups with that have different prognoses. The prognostic factors still ramain controversial. METHODS: Between January 1990 and June 1999, 180 patients with N2 lung cancer who underwent surgical resection were investigated, excluding 10 of these for surgical mortality. All patients underwent mediastinal lymph node dissection. 20 clinicopathologic factors were investigated by univariable and multivariable analyses to identify significant prognostic factors among resected N2 disease. RESULTS: The overall 5-year survival rate was 20.6%. Multivariable analyses among overall patients revealed 3 significant prognostic factors:Age, Histologic type, Vascular invasion. Based on the result, 49 patients with both age more than 60 and pathologic Non-squamous cell showed a 5-year survival of 5.0%, whereas 37 patients with neither of the factors showed a 5-year survival of 56.6%(p<0.001). And 12 patients with both vascular invasion and pathologic Non-squamous cell showed a 5-year survival of 11.9%, whereas 67 patients with neither of the factors showed a 5-year survival of 33.6%(p=0.01). CONCLUSION: The prognosis of surgically resected N2 disease varies according to the 2 significant prognosis factors. Tumor size may be an additional influencing factor in the prognosis of N2 disease.

A clinical observation of cutaneous complications was made on 200 patients receiving cancer chemotherapy at the Department of Internal Medicine, Seoul National University from January through May, 1986. The results were as follows: 1. Among the 200 patients, 191 case(95. 5%) showed cutaneous complications 2. The cutaneous complications included the following; hyperpigmentation(14l cases, 70. 5%), alopecia(138 cases, 69.4%), nail change(118 cases, 59.0%), mucositis(47 cases, 23.5%), dryness of the skin(40 cases, 20.0%), seborrheic dermatitis(24 cases, 12. 2%), increase of seborrheic keratosis(11 cases, 5.6%), folliculitis or acneiform eruptions(9 cases, 4,5%), melasma(6 cases, 3.0%), gynecomastia(3 cases, 1.5%), vessel hardening or dimpling(3 cases, 1.5%), radiation recall(2 cases, 1.0%), hyperhydrosis(2 cases), photosensitivity(1 case, 0.5%), tissue necrosis(1 case), facial flushing(1 case), purpura(1 case) and obesity(1 case), 3 Steps were taken to determine the chemotherapeutic agents causing these cutaneous complications, though in some cases it was difficult in determining exaetlr which chemotherapeutic agent was the cause of the observed cutaneous complication.

PURPOSE: To evaluate surface configuration of intervertebral disc on three dimensional CT. MATERIALS AND METHODS: Three dimensional surface images reconstructed from CTscans(1 mm thick) of 20discs in 14 healthy adults were reviewed. Disc surface was classified into peripheral and central zones in contact with consecutive peripheral ring and central endplate. Local irregularity incidence, pattern in radial, concentric, or mixed form, size, location, and extension were observed. Incidence and severity ranges in 4 grades of general irregularity, and peripheral width relative to central radius were evaluated. RESULTS: Normal disc mostly showed smooth surface with few display of small local irregularity(6/20) which was mainly radial in pattern(4/5), posterolaterally located(4/6), and confined within peripheral zone(5/6). General irregularity displayed(5/20) was all grade I and peripheral width was 0.82 of central radius. CONCLUSION: Normal disc shows smooth surface but few may display small local irregularity maybe due to very early degenerative change.
