The rainwater samples were collected from the 1100 Site of Mt. Halla and Cheju city during the period of March in 1997 to August in 1998, and the major soluble ions were analyzed and their analytical confidence has been investigated. The volume weighted mean values of pH in 1100 Site and Cheju city were 487 and 4.82, respectively, and those of electrical conductivity were 16.0 and 23.3 μS/cm. The mean concentrations of ions in 1100 Site were in the order of Cl^(-)>Na^(+)>SO₄^(2-)>NH₄^(+)>H^(+)>NO₃^(-)>Mg^(2+)>Ca^(2+)>K^(2+)>HCOO^(-)>CH₃COO^(-)>F^(-)>HCO₃^(-)>CH₃SO₃^(-), and those in Cheju city were the same order except that NO₃^(-) was higher than H^(+). The comparison between several correlation coefficients has been applied for the investigation of analytical confidence, such as equivalent concentrations sum, the measured and calculated conductivity, and the acid fraction. The correlation coefficients between cation and anion equivalent concentrations sum were 0.981 and 0.960, respectively, in 1100 Site and Cheju city, and those of the calculated and measured electric conductivity in two regions were 0.989 and 0.993, respectively, so that the analytical data has been shown to be in good reliabilities. Also, the correlation coefficients between the acid fractions from the equivalent concentrations of ions and those from the measured pH and electric conductivity were 0.966 and 0.936, respectively, in two areas, so that these results also have shown a quite satisfactory analytical confidence.

傳統 歌曲의 伴奏旋律에 關한 分析的 硏究 : 男唱, 羽調 二數大葉 系列曲의 奚琴 伴奏 旋律을 中心으로 Centering on the Haegum Part of the Male Voice of UJO I SAKATAEYOP and its Variations

Kagok, one of the most traditional Lyric songs of Korea, is called one of three Chongga together with kasa, sijo. This Lyric song has larger sectional structure and scale, and is accompanied to the musical instruments such as komungo, Kayagum, taegum , p'iri, haegum ,tanso, yanggum, changgo, etc. This Lyric song, beginning in mandaeyop and developing into chungtaeyop, saktaeyop and its variations , nong, nak, p'yon, is considered very important. The purpose of this study is to make a comparative analysis of the melodic differences between ujo i saktaeyop and its variations of male voice part, between voice part and aegum part. The conclusions of the analysis areas follows: Firstly, comparing song part of i saketaeyop with that of its variations in view of melody, the ratio of difference reachs 22.2% in u-chung, 9.9% in u-p'p'yong, 11.1% in u-tu. But the ratio of difference amounts to 22.8% comparing p'yonggo 'kyong-song-ch'ul....' with p'yonggo 'saed-pyol-chi-cha...,' the ratio indicates 14.6% comparing chunggo 'in-shim-un...' with chunggo 'ch'ong-gang-e...'. The musics with the same title, but with different poem may be regarded as more independent than the variations of i saktaeyop with different title. Secondly, as shown in the charter 11, the melody of song part in u-chung, u-p'yong, and u-tu is the reduced or enlarged pattern of the rhythm of u-i for song part, and shows the difference of arranfementcompared with the melody of u-i. Thirdly, as can be noticed in Chart 11, the melodies of song part of u-i, u-chung, u-p'yong,u-tu consist of 'melody A' to 'melody F'. In addition to these 6 kinds of melodies, haegum part includes, melody G' to 'melody J' and the songs are acompaied to the haegum with its distinctive 'melodies, different but harmonious. Its key melody is 'melody A', which its distinctive melodies, diffrent but harmonious. Its key melody is 'melody A', which amosts to 35%(84 melodic patterns of 240). Fourthly, the melodies of haegum part are made up of the almost same as that of song part, but the number of the sounds, different with its corresponding sounds of song parts, increases. (the rate of difference. 25.9%(41 out 158 beats) in u-i, 27.8%(44 out of 158) in uc-hung 36.1%(57 out of 158) in u-'pyong, 46.8%(57 out of 158) in u-tu.) This increase indicates that haegum part comprehends the unique technique of haegum and the distinctive melodies, and has been changed into the unique melodies. Finally, investigating the interval between the sound of haegum part and its counterpart of song part, the interval is mostly composed of fourth interval, that is, when the sound of song part is hwang(Eb), its counterpart of the haegum part is, chung(Ab), when tae(F), it is im or chung(Ab), when chung(Ab), it is tae(F), or im(Bb), when im(Bb), it is chung(Ab) or tae(F) or hwang(Eb), when nam(C), it is tae(F). So far, the melodic comparison between haegum part and song port for male voice of ujo i saktaeyop, chunggo, p'yonggo, tugo have been referred. But many questions remain to be solved; 1) a analysis of the tone before or after the tone which shows difference in both parts. 2) a study of the melodic comparison between song parts and other accompaniment part. 3) a study of the melodies which vary according to poem.

This study was conducted to evaluate the blood lead levels in 141 pregnant women who were not occupationally exposed to lead and their umbilical cord, and to identify some differences in blood lead levels by living area. The subjects were all delivered at St. Benedict Hospital in Pusan and the blood lead levels were measured by graphite furance atomic absorption spectrophotometer. The summarized results were as follows. 1. The geometric mean lead levels in maternal and cord blood were 8.0±1.8μg/dl, 5.0±0.6μg/dl respectively. 2. Lead levels in maternal(8.7±1.7μg/dl) and cord blood(5.4μ±0.7μg/dl) of industrial area(n=24) were higher than residential area(n=124) which were 7.9±1.7μg/dl and 5.0±0.6μg/dl respectively(p<0.05). 3. Maternal blood lead concentration was significantly correlated to cord blood lead concentration(r=0.6090, p<0.001), but other variables(maternal age, paternal smoking, birth weight, etc) were not correlated.

(10) 본 조사군에서는 과거 5년간에 비해 성장발육(체중, 신장, 흉위, 두위, 상완둘레, 피부두께은 큰 차이가 없으나 비만정도, 빈혈, 비타민 D 부족증상은 많은 감소를 보였다. Authors have conducted a study on 442 infants participated in Kyungpook regional wellbaby contest, held in 1982. After through investigation of several parameters including physical growth (body weight, height, chest and head circumferences), nutritional status (Kaup index, serum protein, hematocrit and signs of vitamin C deficiency), and feeding history, along with comparing this with data obtaind from past 5 years (1976-1980), the following results were obtained. Comparing their body weight, height, chest and head circumferences with Korean children's growth standard(K.S.) and Japanese children's growth standard(J.S.), their body weight were superior to those of K.S(2.11-3.19kg) and J.S(1.25-2.25kg), their height superior to those of K.S(4.29-6.75cm) and J.S(2.46-2.73cm) but no remarkable diference between these data and those obtained from past 5 years. Triceps skin fold thickness and scapular thickness were superior to those of Hong(0.4-1.93mm,2.29-2.83mm), the arm circumference were superior to those of Hong(2.19-2.77mm), too. But no remarkable difference between these data and those obtained from past 5 years were found. Total mean serum protein was 7.0gm% in male infants and 7.08gm% in female infants. Kaup index was over 20 in 7.8% in male infants and 6.3% in female infants. Compared to past 5 years, obesity was found less frequently. Breast milk feeding was the most common form of the infant feeding comparing 50.2%, followed by mixed feeding 29.8%, and bottle feeding in 20%. Weaning was started between 4-6 months of age in 56.6% of infants and the vast majority within 12 months of age (98.9%) About 5% of those infants showed anemia, using the cirteria of anemia as being hematocrit less than 33%. They were found in 3.4% of infants with iron-supplemented group, and 5.4% of infants without iron supplementation. In 12.7% of the infants, there were signs of the vitamin D deficiency including Harrison's groove, rachitic rosary, and pigeon chest. They were found in 10% of infants with vitamin D supplementation and 13.6% of infants without supplementation. Compared to past 5 years, anemia and vitamin D deficiency were found less frequently.

1998년부터 2001년까지 제주도 고산에서 대기 에어로졸을 채취, 분석하여 봄철 황사기간 동안의 금속성분 농도와 특성을 조사하였다. 분석기간동안의 평균 농도는 S>Na>Ca>Fe>K>Mg>Zn>Pb>Ti>Mn>V>Ba>Sr>Cu>Ni>Cr>Mo>Cd>Co의 순이었으며, 특히 Al, Ca, Fe, Fe, K, Ti, Ba, Sr의 농도가 황사기간에 각각 10.5, 9.9, 10.3, 5.6, 5.1, 6.5, 5.6배 증가하였다. 대부분의 토양성분들, 특히 Al, Fe, Ca 금속성분은 높은 상관성을 보였으며, 농축인자에 의한 조사결과 Ca, Fe, Cd, Ti, K, Mg 금속 성분들은 주로 토양으로부터 기인하는 반면 Pb, Mn, Ni, Cu, V, Cr, Co, Zn, Na 성분들은 다른 요인에 기인하였다. 요인분석 결과 고산지역의 에어로졸은 토양의 영향을 주로 받고 있으며 그 다음으로는 인위적 및 해염의 영향을 받는 것으로 조사되었다. 풍향별 분석으로부터 대부분의 에어로졸 금속 성분들이 주로 북서계열 풍향의 영향을 받고 있으며 이는 한반도뿐만 아니라 중국 대륙으로부터의 장거리 유입 가능성을 시사하고 있다. The atmospheric aerosols have been collected at Gosan in Jeju during 1998 to 2001, and their metal components have been analyzed in order to investigate the characteristics and concentration variations during the Yellow Sand periods. The mean concentration of metal components including sulfur were in the order of S>Na>Ca>Fe>K>Mg>Zn>Pb>Ti>Mn>V>Ba>Sr>Cu>Ni>Cr>Mo>Cd>Co. The soil originate Al, Ca, Fe, K were increased as 10.5, 9.9, 10.3, 5.6 times, respectively during yellows Sand periods, and Ti, Ba, Sr were also increased as 5.1, 6.5, 5.6 times, respectively. Most of the soil components, in particular, Al, Fe, Ca, showed high correlation coefficients. The enrichment factors show Ca, Fe, Cd, Ti, K, Mg in aerosols are originated mostly from the soil, whereas the metals such as Pb, Mn, Ni, Cu, V, Cr, Co, Zn, and Na are from other possible sources rater than soil. The factor analysis shows the metals of the aerosols at Gosan are originated primarily due to the soil, followed by authropogenic and somehow sea-salt factors. The wind direction study showed most of the aerosol metal components increased with the northwest wind, indicating the possible transportation of air pollutants from China as well as the Korean peninsula.
