The object of this study was to examine the user`s impacts on the environmental deteriorations of trail at Ticket Office - Paekryunsa (Temple) Hyangcho^kpong - Dongyupryung - Chilyun Fall area in To^kyusan National Park. Four trails were sampled in the study area according to the amount of users. Then the user`s impacts on trail were measured at each trail. The Ticket Office-Paekryunsa trail was the mo;;t used district and followed at Paekryunsa-Hyangcho^kpong trail, Hyangcho^kpong-Dongyupryung trail in descending order. Dongyupryung-Chilyun Fall trail is not used by people because of rest rotation system. The entire width of trail was greater at the more heavily used trail. Maximum depth, cross-sectional area loss, and surface texture and roughness of trail were the highest at Paekryunsa-Hyangcho^kpong trail. Soil hardness, soil acidity, soil moisture content, organic matter content, and exchange canon were influenced by trampling. Soil hardness, soil acidity and exchange canon increased in tramples soil, but content of soil moisture and organic matter decreased therein. Environmental deteriorations of trail were significantly influenced by the amount of users and the slope of trail. Bared lands about 2.000㎡ were appeared by trampling and camping around Hyangcho^kpong. Effects of carrying of rest rotation system for National Park were partly recognized at Dongyupryung-Chilyun Fall trail.

측두하악장애환자에서 교합안정장치가 하악골위치변화에 미치는 영향에 관한 연구

천훈,박영국,정규림 대한치과교정학회 2000 대한치과교정학회지 Vol.30 No.4

이 연구는 측두하악장애 증상을 나타내는 부정교합자를 대상으로 교합안정장치 사용 전, 후의 측모 두부방사선 사진 상의 하악골의 위치변화를 구명하는데 그 목적이 있다. 연구의 대상자는 측두하악장애증상을 나타내는 부정교합자 60명이며 남자 19명, 여자 41명으로 각각의 평균연령은 19.5세와 21.5세 이었다. 전체 대상자를 전, 후방적으로는 Angle 분류법에 따른 교합관계에 의하여 Class Ⅰ, Ⅱ, Ⅲ로 분류하였고, 수직적으로는 Jarabak의 후안면고경과 전안면고경의 비율에 따라서 clockwise, straight downward, counterclockwise의 3군으로 구분하여 부정교합군 별로 측정했으며 하악골의 위치변화를 중심교합시의 측모 두부방사선 사진 계측치 들로부터 예측할 수 있는지 알아보기 위한 분석을 시행한 것으로 다음과 같은 결과를 얻었다. 1.전체 대상자 비교시 측두하악장애를 갖는 부정교합환자에서 교합안정장치 사용 이후 하악골은 후하방 회전을 나타내었고 overjet은 1.3mm의 증가, overbite은 1.9mm 감소되어 수평변화보다 수직적인 변화의 양이 컸다. 2.전후방 3군 분류시 하악골의 후하방 변위를 나타내는 항목의 유의성 있는 변화는 Class Ⅱ군에서 가장 현저하였으며 3군중 후방변위량이 가장 컸다. 3.수직 3군 분류시 Clockwise와 counterclockwise군에서 하악골의 후하방 변위를 나타내는 항목의 유의성 있는 변화가 뚜렷하였으며, 3군 모두에서 수직적인 변화량이 수평변화량 보다 컸다. 4.중심교합위시의 부정교합 양태 및 골격유형, 그리고 중심교합위 계측치를 통하여 중심위 계측치를 설명할 수 있는 항목은 발견되지 않았다. 이상의 결과는 기존에 시행되어 오던 중심위 전환에 의한 방법이 아니고 측두하악장애를 갖는 부정교합자에서 교합 안정장치를 장착하여 중심위를 획득한 상태에서 하악골의 위치변화를 계측한 것으로 측두하악장애를 동반한 부정교합환자에서 중심교합위 상태의 측모 두부방사선 사진에 의존한 진단은 부정교합의 실체를 파악할 수 없음을 확인하였으며, 통상적으로 이용되어 온 중심위 전환방법 역시 중심위 유도후 발생되는 수직적인 부조화의 양상을 나타낼 수 없음을 입증하였다. 또한 전, 후방적으로는 Class Ⅱ 부정 교합군, 수직적으로는 Clockwise군과 Counterclockwise군에서 교합안정장치를 사용한 중심위 회복시에 하악골의 후하방 회전과 이에 동반된 구치부의 교합간섭으로 전후방 부조화뿐 아니라 수직적부조화를 더욱 심화시키므로 이에 대한 진단 및 치료시의 고려가 요구됨을 보여주었다. The purpose of this study was to investigate if there were a significant differences in mandibular position between cephalometric measurements from a centric occlusion tracing compared to those of a acquired centric relation by stabilization splint on malocclusion patient with TMD. 60 malocclusion patients, who had TMD and CO-CR discrepancy beyond normal range, were selected and subdivided into Class I, II, III by Angle's classification and also subdivided into clockwise, straight downward, and counterclockwise group by Jarabak's posterior facial height / anterior facial height ratio. Lateral cephaolmetric radiographs with the mandible in centric occlusion were taken and measured, and for each patient the stabilization splint with mutually protected occlusal scheme was applied for minimum 3months. After each patient's CO-CR discrepancy was in normal range, lateral cephalometric radiographs were retaken and measured. The comparison of the difference between CO-CR cephalometric measurements in all sample, Class I, II, III groups, and Clockwise, Straight downward, Counterclockwise groups were studied. The finding of this study can be summarized as follows: 1.In all sample, the value of cephalometric measurements was significantly different between CO-CR. The mandible rotated to down and posterior position and the vertical change was greater than the horizontal change (overjet-1.3mm increase, overbite-1.9mm decrease). 2.In Class II malocclusion group, most of the mean difference value between CO-CR is higher than that of the other groups and more measurements was statically significant. 3.In clockwise and counterclockwise group, some of the mean difference value is higher than that of straight downward group and more measurements was statically significant. 4.There ware no measurements that explain centric relation measurements from the type of malocclusion, facial pattern and centric occlusion measurements. Henceforth, it is strongly recommended that stabilization splint therapy for orthodontic treatment on TMD patient should be excuted upon overall facial types prior to orthodontic diagnosis and treatment planning.

This study investigates the regulations on concrete grade evaluation, in response to operation of housing performance grade system(HGS). It also studies countermeasure- of ready mixed concrete industry. Because the HGS provide people who have to invest in housing once during their whole life, with objective information of housing performance, housing consumers would easily understand and purchase better house. In addition housing construction companies will try to supply the high quality housing, in response to people's various housing performance needs. It is expected that housing quality improvement and housing components technology development will be nationally activated, due to the competition on housing quality between the construction companies. After this, HGS is now on design process but will be on construction process connecting specification, which is perfoiniance based design and on the process after completion. It is assumed that those regulations will be possibly continued to develope for housing performance guarantee system.

This paper investigated the engineering properties of cement mortar mixed with more than two kinds of fine aggregate. For fresh mortar properties, unit volume weight is constant regardless of mixing content and type of fine aggregate. An increase in contents of natural fine aggregate and crushed fine aggregate resulted in an increase in flow, whereas an increase in recycled fine aggregate contents reduced flow. Gap between maximum flow in N_(3)C_(0)R_(0) and minimum flow in N_(0)C_(0)R_(3) exhibited about 12%. Compressive strength at 28 days ranged from 32 to 36 MPa in order for crushed fine aggregate, natural fine aggregate and crushed fine aggregate showed compressive strength comparable to that of crushed fine aggregate. An increase of fraction of recycled fine aggregate in mixed fine aggregate resulted in a decrease in compressive strength. For drying shrinkage, N_(0)C_(0)R_(3) had the largest drying shrinkage among various mixture type. The combination of large contents of recycled fine aggregate and small contents of natural and crushed fine aggregate had a large amount of drying shrinkage.

The current study was designed to evaluate the positive rates of arthropod allergens by Korean inhalant panel of MAST-CLA in patients with allergic rhinitis. One hundred sixty patients, diagnosed to allergic rhinitis in an Out Patient Center of Soonchunhyang University Chunan Hopsital during Aug 1998 to July 2000, were studied. 1. The overall positive rate among 35 specific allergens was 59.4% (95 patients). 2. The arthropod related allergen accounted for 82.1% (78 patients) of the positive rate. 3. Each positive rate of Dermatophagoides farinae (Df), Dermatophagoides pteronyssinus (Dp), house dust (Hd), and cockroach mix (Cm) was 45.0% (72 patients), 43.1% (69 patients), 28.1% (45 patients), and 8.8% (14 patients), respectively. 4.Significant agreement between arthropod allergens was observer (P < 0.05). 5. The obseved agreement between Df and Dp was 95.6%, showing most significant Kappa index (Kappa = 0.911, P < 0.001). There results suggested that although MAST-CLA is a useful measure of identifying specific allergens, the specificity of two mite allergen relatively low, implying because of common allergen between mites in Korean panel of MAST-CLA. Our data also supported that arthropod is the major cause of allergen in patients with allergic rhinitis, however, the MAST-CLA should be modified in order to exclude common allergen of mite and to include more specific mite allergen.

To evaluate usefulness of application of MAST-CLA to indetify allergens, authors conducted MAST-CLA allergen-specific IgE assay and collected allergy related symptoms in 118 allergic patients diagnosed at Soonchunhyang University Chunan Hospital during October 1998 through January 2000. The results were as followings; 1. The mean (SD) age was 23.1 (±12.17) years old and teenagers accounted for 33.1% of patients. 2. The frequent allergic symptoms were sneezing (59.3%), rhinorrhea (53.4%), nasal stiffness (44.1%), itching sensation (24.6%), cough or sputum (16.1%), and eye symptom (8.5%) in order. 3. Among these subjects, 62.7% of patients revealed at least more than one specific allergen and 70.3% showed elevated total IgE levels by MAST-CLA. The three most frequent specific allergens were Dermatophagoides farinae (47.5%), Dermatophagoides pteronyssinus (45.8%), and house dust (30.5%). 4. While age was not significantly related to positive of both specific allergens and total IgE (P>0.05), sneezing and nasal stiffness were significantly associated with positive of specific allergen and total IgE, respectively (both P<0.05). 5. Total IgE increased with the number of specific allergens, but both specific allergen and total IgE were not significantly related to increases of allergic symptoms (P>0.05). In conclusion, our data suggest that MAST-CLA allergen-specific IgE assay is useful measure for identification of causative allergens in allergic patients, however, it is recommended that more specific allergic antigens should be determined and replaced or added to Korean inhalent panel of MAST-CLA.
