Korean fir(Abies koreana E.H.Wilson 1920), endemic tree species of Korean peninsula, is considered as vulnerable and endangered species to recent rapid environmental changes such as land use and climate change. There are limited activities and efforts to find natural habitats of Korean fir for conservation of the species and habitats. In this study, by applying SDMs (Species Distribution Models) based on climate and topographic factors of Korean fir, we developed Korean fir’s predicted distribution model and explored novel natural habitats. In Mt. Shinbulsan, Youngnam region and Mt. Songnisan, we could find korean fir’s two novel habitat and the former was the warmest(13°C in annual mean temperature), the driest(1,200mm∼1,600mm in annual rainfall) and relatively low altitude environment among Korean fir’s habitats in Korea. The result of SDMs did not include mountain areas of Gangwon-do as habitats of A. nephrolepis, because there were different contributions of key habitat environment factors, summer rainfall, winter mean temperature and winter rainfall, between A. koreana and A. nephrolepis. Our results raise modification of other distribution models on Korean fir. Novel habitat of Korean fir in Mt. Shinbulsan revealed similar habitat affinity of the species, ridgy and rocky site, with other habitats in Korea. Our results also suggest potential areas for creation of Korea fir’s alternative habitats through species reintroduction in landscape and ecosystem level.

Exercise training is highly correlated with the reduced glucose-stimulated insulin secretion (GSIS), although it enhanced insulin sensitivity, glucose uptake and glucose transporter expression to reduce severity of diabetic symptoms. This study investigated the impact of short-term swimming exercise on insulin regulation in the Goto-Kakizaki (GK) rat as a non-obese model of non-insulin-dependent diabetes mellitus. Wistar (W/S) and GK rats were trained 2 hours daily with the swimming exercise for 4 weeks, and then the changes in the metabolism of insulin and glucose were assessed. Body weight was markedly decreased in the exercised GK rats compare to their non-exercised counterpart, while W/S rats did not show any exercise-related changes. Glucose concentration was not changed by exercise, although impaired glucose tolerance was improved in GK rats 120 min after glucose injection. However, insulin concentration was decreased by swimming exercise as in the decrease of GSIS after running exercise. To identify the other cause for exercise-induced insulin down-regulation, the changes in the levels of key factors involved in insulin production (C-peptide) and clearance (insulin-degrading enzyme; IDE) were measured in W/S and GK rats. The C-peptide level was maintained while IDE expression increased markedly. Therefore, these results showed that insulin down-regulation induced by short-term swimming exercise likely attributes to enhanced insulin clearance via IDE over-expression than by altered insulin production.

Posterior crossbite is defined as an abnormal buccal or lingual relationship of a tooth or teeth of maxilla, the mandible or both when the teeth of the two arches are in occlusion. It may include one or more teeth, and it may be unilateral or bilateral. These posterior crossbites develop early and are not self-correcting, and the treatment of primary dentition crossbite favors development of normal occlusion in the mixed dentition. Especially, crossbites caused by a mandibular shift should be treated as soon as they are discovered and are among the few conditions recommended for treatment in the complete primary dentition. An untreated mandibular shift can produce undesirable growth modification, dental compensation leading to a true asymmetry at a later time, and potentially harmful functional patterns. The next two children came to the clinic with the chief complaint of unilateral posterior crossbite due to a width discrepancy of the maxilla or mandible and a lateral mandibular deviation. Their posterior crossbites were corrected using the lateral expansions of the constricted arch.

PUK is an autosomal recessive disorder attributable to a deficiency or defect in phenylalanine hydroxylase, an enzyme produced almost exclusively by the liver and responsible for the conversion of phenylalanine to tyrosine. Untreated PKU causes severe mental retardation, musty ordor, hyperactivity, seizures, eczema and hypopigmentation. The purpose of this study was to assess the effect of PKU to the oral structures and to collect the data for prevention and treatment of their dental diseases. Sixteen PKU children and sixteen unaffected normal children were examined and analyzed. The results were as follows: 1. In PKU group, DMFT rate was 10.5% and deft rate 28.3%. 2. The prevalence of enamel defects in PKU group was 50% and that in control group was 6.3%. The average number of enamel defects in PKU group was significantly higher than in control group(p<0.05). 3. The simplified Oral Hygiene Index and the frequency of toothbrushing in PKU group were not significantly different from that in control group(p>0.05). The rate of parents who give help with their children´s toothbrusing in the PKU group was significantly higher than that in control group(p<0.05). 4. There was no significantly difference betwwen the two groups in Periodontal Index(p>0.05). 5. The Class II malocclusion was the most common status of occlusion in PKU group, but the Class I malocclusion in control group. 6. The 43.8% of children in PKU group and the 6.3% in control group exhibited an oral habit that was considered abnormal. 7. There was no characteristic abnormality of oral mucosa, palate and tongue in both PKU and control groups.

The authors studied on the effects of explosion at the sloped apple orchards to the moisture content in the soil, growth rate of newly formed shoot and root, quality and quantity of the fruit produced at two exploded plot in 1967. and not-exploded plot in this year. The results obtained can be summarized as follows; 1) In the soil moisture content, the exploded pot maintained 20-25% of moisture even during dry season and didn't exceed over 30-35% during rainy season. Thus moisture content was controlled for the growth of the tree as suitable, while control plot decreased below 20-25% dur ing dry season and rose by 40~45% during rainy season. So it suffered from danage of moisture content in the soil. 2) Height of the tree was over 13.2% when comparing with control plot and growth rate of the trunk was 2.8%. Shoot elongation of the exploded plot was over 27.2% than the control plot. 3) The root growth of the apple tree the orchard exploded in 1967 was strikingly spread in the soil while in the control plot, root growth was retarded as crooked severely and root hairs a few and that the roots of the control plot was infested by Woolly apple aphid resulting in the weak shoot growth. 4) In the leaf analysis of the apple tree, N, K, Ca and Mg content were higher than the control plot except P_2O_5 It seems to be incresed the root growth and absorption of the nutritions to the leaf. From these results, we believed, augumentation of the fruits can be expected. 5) The fruit height of apple produced from the exploded plot was higher by 7-8% than control plot and the fruit diameter was more over 5-6% than wide control plot. In the number of the fruit at the exploded plot was numerous over 47% than that of the control plot and the fruit weight also increased by 64% in the exploded plot.

ABSTRCT Four rape cultivars were grown at 1 to 5 plants per hill to investigate the effects of the number of plants per hill on major agronomic characters of forage rape in Cheju volcanic soil. Days to flowering of Sparta was 191 days, those of Ramon and Youngsanyuchae were 189 and 188 days, respectively. And that of Hallayuchae was 180.3 days. Days to flowering decreased as number of plants per hill was increased. Sparta was tallest (153.6cm), while Hallayuchae was shortest (131.8cm). Plant height with three plants per hill( 155.3cm) was longest, while with 5 plants per hill(131.8cm) was shortest. The number of branches, stem diameter, leaf length and leaf width gradually decreased as the number of plants per hill were increased. Sparta had the greatest fresh and dry matter, total digestible nutrient (TDN) and crude protein yields, while Hallayuchae had the least. Fresh yield were greatest (7,544 kg) at the three plants per hill. Dry matter TDN, and crude protein yields were also greatest (7,544 kg) at the three plants per hill. Ramon had the greatist SPAD reading (44.7) while Youngsanyuchae had the lowest (40.7). SPAD reading were highest (44,1) in the one plant per hill plot but decreased as the number of plants per plant was increased. Sparta had greater contents of crude fiber and crude ash, but Hallayuchae and Youngsanyuchae had lower contents. The content of crude protein, crude fat, nitrogen free extract(NFE) and TDN were increased as number of plant per hill were increased. But the contents of crude fiber and crude ash were decreased as the number of plants per hill was increased.

목 적 : 본 연구는 직업성 연 폭로근로자에서 연폭로가 남성 생식기계 독성중 성호르몬에 미치는 영향과 그 정도를 평가하고자 시도되었다.방 법 1998년 하반기에 실시한 일반, 특수건강진단자중 경기도 지역 직업성 연 폭로 근로자 33명과 과거 직업력에서 연 폭로가 없었던 사무직 근로자 33명을 연구대상으로 선정하였다. 연의 생물학적지표로는 혈색소, ZPP, 혈중 연, 및 요중 연을 이용하였으며, 성호르몬으로는 LH, FSH, testos-terone, SHBG 및 FTI를 이용하였다. 연 폭로 지표와 성호르몬과의 상관관계를 조사하였다. 결 과 : 연의 생물학적 지표중 혈색소는 폭로군에서 대조군보다 유의하게 낮았으며, ZPP, 혈중 연및 요중 연등은 폭로군에서 대조군보다 유의하게 높았다. 성호르몬에서 FSH, testosterone, SHBG및 FTI는 모두 폭로군에서 대조군보다 낮았으나 통계적 유의성은 없었다. 폭로군의 성호르몬중에서 연령은 FSH 및 FTI, ZPP는 FSH, 혈중 연은testosterone과 유의한 상관관계가 있었다. 대조군에서 연령은 FSH, testosterone, SHBG 및 FTI와 흡연량은 FSH와 유의한 상관관계가 있었다. 연령군별 폭로군과 대조군의 성호르몬 비교에서 30-39세군의 FTI에서 폭로군이 대조군보다 유의하게 낮았으며 그 밖의 호르몬에서는 모두 유의한 차이가 없었다. 결 론 : 연 폭로군의 FSH, Testosterone, SHBG 및 FTI가 대조군에 비교하여 낮았으나 통계적 유의성은 없었다. 그러나 폭로군에서 연의 생물학적 지표와 일부 성호르몬간에 유의한 상관관계를보였으며 이는 본 연구 대상 근로자의 연 폭로 수준이 일부 성호르몬에 영향이 있음을 보여주는 것으로 판단된다. 향후 이에 대한 지속적인 연구가 진행되어 야 할 것이다. Objectives : This study was performed to evaluate the relationship between biological markers of lead exposure and level of sex. hormones in men occupationally exposed to lead. Methods : In this study, 33 male workers who employed at smelting and battery factories were compared with 33 male workers who were not exposed to lead. As biological markers of lead exposure, hemoglobin, ZPP, blood lead and urine lead were measured. As sex hormones, FSH, LH, testosterone, SHBG and FTI were determined. Results : Hemoglobin level was significantly lower in exposed than in nonexposed group. Level of ZPP, blood lead, and urine lead were significantly higher in exposed than in nonexposed group. There was a trend that level of FSH, testosterone, SHBG, and FTI was lower in exposed than in nonexposed group respectively, but there were no statistical significance. In exposed group, FSH level was correlated with age, ZPP, and blood lead; testosterone level was correlated with hemoglobin, blood lead, urine lead, and SHBG ; and FTI level was correlated with age. Conclusions : Level of some sex hormones were lower in exposed than in nonexposed group but there were no statistical significance between the exposed and the nonexposed group. But level of sex hormones were correlated with several biological markers of lead in exposed group. It suggests that occupational lead exposure might affect sex hormones.

Angelicae gigantis radix is the root of the perennial plant, which belongs to family Umbelliferae. However, this herbal drug has quite different chemical components according to its different geographical origin though other herbal drugs (i.e. Leonuri Herba, Xanthii Fructus and so on) show similar major constituents. In other word, the root of Angelica gigas containing the coumarin compounds is commonly used in Korea as Angelicae gigantis radix, while Angelica sinensis and Angelica acutiloba including phthalide compounds are used in China and Japan, respectively. In this paper, Near-Infrared spectroscopy was developed to determine Genus name of Angelica spp., especially Angelica gigas and Angelica sinensis which are generally misused in the herbal market. Also X-ray fluorescence spectrometry was evaluated to analyze the differences between Angelica gigas and Angelica sinensis with their specific properties.

New active organic thin film optical wavegudie ion sensor is proposed. Poly-dimethylsiloxane(RTV3140) membrane based on indicator tetramethylmurexide (TMX) and co-polymer matric membrane based chromoionophore(ETH5294) were used as active waveguide itself. Utilizing thin film membrane, fast respense time and high sensitivity are obtained. And sensor could be measured a wide range of Ca^(++) concentrations ranging from 10^(-6) to 1M by measuring the absorbance change at the 488nm and 514nm wavelength of light. The dependence of attenuation of guided wave on the properties of transduction layer is discussed.
