The effects of acidic aerosols have been reported to be more severe, so the recent studies were focused on identifying the characteristics of acidic aerosols, and their formation mechanisms. Therefore in this study the cyclon/annular deluder/filter pack sampling system was sued to collect and evaluate acidic aerosols in Pusan area in order to investigate the variation characteristics of the secondary inorganic pollutants(SO₄,NO₃). Forty-eight 12-hr average samples, equally divided into day/night intervals, were collected at Kwangan-dong sampling site where continuous air monitoring system was operated, from June, 1995 to November, 1995. The important conclusions obtained in this study were as followings ; The highest and lowest values of monthly averaged concentration occurred in July(12.47±3.15㎍/㎥) and september (4.00±3.15㎍/㎥) for SO₄, and in July(4.10±4.76㎍/㎥), and September(0.41±0.39㎍/㎥) for NO₃. These concentration levels were in the same range as observations in other urban areas. In order to examine the relationships between the concentrations of sulfate and nitrate, and their influencing factors, the correlation analysis was conducted. From the results of correlation analysis, the following results were obtained : 1) the value of correlation coefficient between SO₄, and SO₂showed higher in daytime(r=0.46) than in nighttime (r=0.38), and in summer season(r=0.61) than in autumn season(r=0.15) and in condition of relative humidity less than 70%(r=0.50) than in condition of relative humidity more than 70%(r=0.35). 2) Especially the SO₄concentration has the highest correlationships (r=0.94) to SO₂concentration for the data of daytime in summer. 3) The value of correlation coefficient between NO₃ and NO₂ showed higher in daytime(r=0.41) than in nighttime(r=0.74), especially showed highest value(r=0.74) for the data of nighttime in summer. 4) The NO₃concentration has the reverse correlationships to temperature, and the highest value of correlation was calculated as -0.69 for the data of daytime of autumn. From the above results about concentration characteristics and correlationships for SO₄and NO₃, the following comprehensive conclusions were obtained : 1) There were similar trends of concentration variation between SO₄and NO₃. 2) The concentration of SO₄was closely related with relative humidity but that of NO₃ was related with atmospheric temperature. 3) The formation mechanism by photochemical action and NH₄NO₃dissociation reaction were considered to have influence on the concentration variation of SO₄and NO₄.

This experimental study is to find out the physical endurance through heart rates according to the intensity of exercise. The experiment was applied to personal-game players in athletics, swimming, boxing and skating, and to team players in handball, volleyball, basketball and soccer, and to non-players. The intensity of exercise was divided into five kinds (12, 18, 24, 30, 36 times/minute) according to the speed of going up and down the wooden steps made for the test. Heart rates were measured while players and non-players under test were resting from one minute and a half to two minutes after exercise. The measurement of heart rates, twice in all, was took once every second day by using 108 system heart checker. T-test were applied to find out the average difference among three groups. 1. Heart rates of personal-game players were as follows: 131.0±10.53 beats/minute during the exercise intensity of 12 times/minute; 136.2±12.28 beats/minute during 18 times/minute; 139.1±11.9 beats/minute during 24 times/minute; 141.1±13.3 beats/minute during 30 times/minute; 144.5± 6.92 beats/minute during 36 times/minute: 2. Heart rates of team game players ranged as follows: 131.8±8.3 beats/minute during the exercise intensity of 12 times/minute; 138.0±9.89 beats/minute during 18 times/minute; 143.4±9.11 beats/minute during 24 times/minute; 148.5±9.64 beats/minute during 30 times/minute; 156.2±8.42 beats/minute during 36 times/minute. 3. Heart rates of non-players were as follow: 154.2±13.85 beats/minute during the exercise intensity of 12 times/minute; 155.6±15.62 beats/minute during 18 times/minute; 164.6±12.88 beats/minute during 24 times/minute; 172.4±13.37 beats/minute during 30 times/minute; 189.6±16.49 beats/minute during 36 times/minute. 4. All of the personal and team-game players under test had more excellent physical endurance than non-players, and showed less heart rates when tested in the five kinds of exercise intensity. Especially, both of them indicated more physical endurance when the exercise intensity increased A small gap of difference arose among each personal and team-game player in heart rates under the exercise intensity of 30 times/minute, but personal game players indicated less heart rates than team-game players when the intensity became 36 times/minute. (P<0.05). The most significant of the results in this research was the fact that a wider difference came out between personal and team-game players during the exercise intensity of 36 times/minute.

In the five years since 1993 Malaria has made a ceaseless attack on the native Koreans as an indigenously formed disease in addition to the imported one. This study was aimed at clinical symptoms and signs of Malaria which had occurred indigenously in Cheon-Nam. 18 cases were reviewed retrospectively in this study which was composed of 17 men and 1 woman. They were admitted to Chosun Hospital because of the indigenous Malaria in 1998. Fever and chill , the most frequent symptoms in early stages made a 100% occurrence followed by general myalgia(89%) and headache(83%). Physical examination of those admitted showed the splenomegaly most frequently in 61% of the patients. It took four to ten days to visit the hospital since the symptoms first occurred in the patients. Gametocytes among the Malarial life cycle were observed most commonly (91.3%) in the occurrence of the disease and the prestages of the life cycle as well. The hematologic abnormalities observed was Anemia(89%), Thrombocytopenia(61%), and Neutropenia(50%) in the order named. On the third hospital day since giving the standard Malarial drugs parasitemia decreased remarkably (1540/㎕ : Mean parasitic concentration) and 28th day of treatment no parasitemia were found. In conclusion the patients suffering from malaria in Cheon-Nam had been in an armistice area and the symptoms were so relatively mild that the responses to treatment were good and relapses occurred. But, it requires further epidemiologic survey and more concern about the indigenous Malaria.

Background and Objectives: Satisfactory results have not been obtained with recent therapeutic methods for advanced or recurrent head and neck cancer. Simultaneous chemoradiotherapy has the purposes of overcoming radiation resistance, which is the cause of local treatment failure and of early treatment for distant micrometastasis, which is the cause of systemic treatment failure. Thus, we investigated effects and complications of chemoradiotherapy in head and neck cancer. Materials and Methods: We examined the effectiveness of the simultaneous chemoradiotherapy in 22 histologically confirmed patients with head and neck cancer. Group 1 included 9 patients who have recurrent head and neck cancer after radical treatment and group 2 included 13 patients who have advanced head and neck cancer. We decided to perform chemotherapy with cisplatin (or leucovorin), hydroxyurea, and 5-fluorouracil and daily radiation therapy with 180-200 cGy every other week. Results: The median follow-up period was 32 months. In those patients treated, the response rate was 80%(12/15) and complete response rate was 60%(9/15). Patients in group 1 showed a low response rate with 60%(3/5) whereas those in group 2 showed a high response rate with 90%(9/10) after treatment. The mean period of disease progression was 4.4 months for the patients in group 1 and was beyond the end point of follow up period in group 2. Although 5 out of 9 patients failed locally, those in group 2 showed no local failure. Hematologic toxicity was the most common complication in the treatment. Mucositis was the second significant complication and it was expressed more during the period when leucovorin was included in the treatment. Conclusion: It is thought that simultaneous chemoradiotherapy is more effective than previous therapeutic methods in treatment of those patients with head and neck cancer with poor prognosis. Additional investigations on the survival rate and the causes of unresponsiveness to chemoradiotherapy remains to be done in the future.
