거창분지 퇴적물의 모래의 형태와 표면상태에 관한 연구

최한성 서울대학교 지리교육과 1995 地理敎育論集 Vol.33 No.1

한국의 산간 분지는 일반적으로 침식 분지로 알려져 있다. 최근 이러한 침식 분지 내에 남겨진 퇴적물에 대한 분석이 이루어지고 있다. 거창 분지는 덕유가야산지에 발달되어 있는데, 분지 내의 구릉과 평탄지 말단부에 퇴적물이 나타난다. 본 연구에서는 이러한 퇴적물을 분석하여 개략의 퇴적물 공급지와 이동 거리를 추정하고자 하였다. 이를 위하여 거창 분지에 잔존하고 있는 퇴적물 노두를 기술하고, 이들 퇴적물의 입경 분석을 행하였다. 또한 이 퇴적물 중에서 모래 층과 모래 입자에 대한 형태와 표면 상태에 대한 현미경 관찰을 하였다. 이러한 모래 입자에 대한 분석에는 중급 모래(200~630㎛)를 이용하였다. 석영의 모래 입자는 다른 광물에 비하여 상대적으로 풍화와 침식에 강하기 때문에 대략의 풍화 양상, 운반 과정과 이동 거리 등을 추론하여 볼 수 있다고 여겨지기 때문이었다. 거창 분지에 나타나는 노두 중에서 4개를 선택하여 퇴적물을 분석한 결과 점토를 최고 58%까지 함유한 층들이 나타나고 있으며, 모래 분석을 한 결과는 대부분의 모래 입자들은 원마되지 않은 각력의 상태로 있으며, 광택이 나는 입자로 존재한다. 간혹 표면에 미세한 오목한 모양을 한 것도 있다. 종합하여 보면 모래의 공급원은 가까운 곳의 기반암 풍화층으로 사료되며, 이동 거리는 매우 짧았던 것으로 추정된다.

P u r p o s e: This study was performed to evaluate the difference in effectiveness between two cervical orthoses, the Philadelphia collar (Philadelphia Collar Co., Philadelphia, PA) and the Stifneck (Laerdal, Armonk, NY), in their ability to restrict cervical motion in flexion, extension, lateral tilt, rotation, and intervertebral motion in Koreans. M e t h o d s: Ten volunteers, young Korean men (26∼4 2 years of age), with clinically and radiographically normal cervical spines were studied. The normal and unrestricted ranges of active cervical motion in flexion, extension, and lateral tilt were measured in each subject and compared with the motion permitted in each of the two cervical orthoses. R e s u l t s: This study demonstrated the Stifneck collar’s superiority over the Philadelphia collar in extension, rotation, and lateral tilt, but not in flexion. The efficacies of the two collars in restricting intervertebral movement are good except between the 1st and the 2nd cervical vertebrae. The reason is the cervical vertebrae do not move as one unit; paradoxical motion, the phenomenon o“f sn a k i n g , ”oc c u r s . Compared to the results for the cervical spines of a Caucasian population, our results revealed that the combined flexion-extension of the cervical spine was markedly less restricted with both cervical orthoses. C o n c l u s i o n: The first obvious implication of the “s n a k i n g ph e n o m e n o n ”is that measurements o“f total overall”ce r v i - cal spine motion may be misleading. The limited effectiveness of restriction at maximum combined flexion-extension suggests that the anatomy of the skull in Asians might differ from that of Caucasians, leading us to believe that a new type of orthosis based on Asian anatomy needs to be developed, and produced.

Background : The purpose of this study was to apply cervical orthosis for temporal parameters of gait was to evaluate the effect. Methods : Seven normal adults participated in this study. Before and after applying a cervical orthosis compared to gait. Outcome measure were: general characteristics, temporal parameters of gait. General chacteristics included age, gender, height, weight. Temporal parameters included the Velocity cycle, Stride length, Step length, Cadence cycle, Initial double support time. Temporal parameters of gait, using the motion analysis system for cervical orthosis were evaluated before and after applying. The data was analyzed using SPSS 12.0 software and the Wilcoxon's signed-ranks test. Results : Velocity cycle and Step length were no significant differences(p>0.05). But Stride length, Cadence cycle, Initial double support time were significant(p<0.05). After apply Cervical orthosis in gait, Stride length and Initial double support time was decreased and Cadence cycle was increased. Conclusion : Changes in temporal of temporal parameters of gait was apply a cervical orthosis with the limitations of vision due to take effect. Therefore, Cervical orthosis does not interfere with the normal gait pattern by limiting the Range of Motion so that we consider to apply.

Significant Ritual Elements of The Sarum Rite for the Korean Methodist Church

최한성 한국실천신학회 2019 신학과 실천 Vol.0 No.65

The Sarum Rite (The SR) not only facilitates sacred objects such as salt, saliva, oil, a white cloth, and a burning candle but also bodily ritual actions such as “eating salt,” “spiting and touching with saliva,” “wearing a white cloth,” and “dipping the baptizand’s head/body into water and turning their head/body to the side of south, east, and north by turns in the water.” As for The SR, sacred objects and bodily ritual actions play a significant role in helping candidates actively participate in their baptismal rite. With regard to the baptism of the Korean Methodist Church (the KMC), The Korean Methodist New Book of Worship (The KMBW) rarely applies sacred objects and bodily ritual actions. This impoverished use of sacred objects and moderate ritual actions might not help the candidate actively participate in his or her baptismal rite. As a result, this passive participation of the baptizand might make his or her baptism a perfunctory ritual. Hence, the KMC needs to consider applying for sacred objects and bodily ritual actions. The KMC can learn significant ritual elements in terms of theological and liturgical aspects from The SR. The KMC does not need to follow the sacred objects and bodily ritual actions The SR uses. The KMC can develop any sacred objects and bodily ritual actions based on their sociocultural context for their baptism. The KMC can dynamically partake in their baptismal rite and make their baptism a more powerful, meaningful, and graceful ritual through using sacred objects and bodily ritual actions.

최근 5 년간의 " Praxis Geographie " 를 통하여 본 독일의 지리과 수업에서의 Computer 와 Telekommunikation 의 이용에 대한 소고

최한성 서울대학교 지리교육과 1996 地理敎育論集 Vol.35 No.1

New educational changes are forecasted to come to Korea reflecting the wide use of computers and the utilization of telecommunication. It is necessary to discuss how the current trends in technology will effect geography courses in Korean schools. However, because geography courses are very sensitive to the requirements for the national entrance examination, it is difficult to predict the changes in courses in the future. Therefore, it is very useful to look outside of Korea and see how other countries have assimilated technology into course work. For this paper, Germany was selected as the subject country. This study involves a description of the computer, software and telecommunication utilization for geography courses in Germany. In order to understand the trend in Germany, the contents of the magazine $quot;Praxis Geography$quot; were reviewed. ($quot;Praxis Geography$quot; is a popular professional magazine for the teaching and study of geography in Germany.) A review of the magazine's contents for the last five years indicates that regional studies and systematic geography are strongly linked. A monthly theme about computer-software for geography courses was covered in volume 3/1995. In this volume, the spread and utilization of computers in German schools was discussed. Also included in this volume were a geography syllabus that integrated computers, software for geography classes, methods of networking, trends of teaching geography and some critical analysis of courses. In this paper a few software products which are popular for geography courses in Germany such as Wega, HIima, Hunger in Afrika, IDRISI, MOBIT, RUDI-RUHR, SimCity, were briefly introduced. According to the magazines it is necessary to promote the widespread use of computers in schools and to invest in the development of adequate software, in order to complete geogprahical courses in Germany; it is also very important to study the negative effects in rapidly changing the educational environment by introducing computers into geography courses.

中國 延邊地域의 관광자원과 한국 단체 관광에 대한 고찰

Since the diplomatic relationships between Korea and China are established, a number of Korean touristics and package tours to China are growing increasingly. Therefore it is needed to analyse this touristic phenomena and to estimate this trend, in order to exploit touristic resources and to develope new concepts in tourism. The purpose of this theses is to classify the touristic resources in Yenbyon and to analyse the Korean package tours of this area and to suggest improved touristic plans. The touristic resources for Korean visitors in Yenbyon could be classified into nature geographical group, ancient and medieval historical relic, anti-Japanese remains and present socioeconomic types. Natural touristic resources are mainly existed in Mt. Paekdusan and its circumference, which are made up volcanos and lav plateaus, where vertical distribution zones of vegetation are formed. Most of historical relic in Yenbyon take their rises from Balhae(Pohai)-Dynastie. The anti-japanese remains against military imperial colonialism are too potential resources for Korean. Yenbyon is located in border land between North-Korea, China and Russia. As the border land there are also attractive social and political touristic resources in example customs and gates between the nations. According to the analyse of package tour programmes Mt. Paekdusan and its circumferential areas are major tourist resorts and the others play auxiliary roles in Korean package tours. These Paekdusan tours are limited only within summer seasons because of the winter weather conditions. These tours provide simple programme, which consist of climbing the mountain and sighting the lake Chonji and water falls. It can be suggested that the programmes of these tours are needed to be diverse and to be arranged closely with other touristic resources in this region. Especially on the basis of natural environment in this region ecotourism will be practical and realizable idea. It is also thinkable to organize thema tours from various touristic resources, for instance historical tour, cultural tour, city tour or ecotour etc. For these purposes it is necessary to train guiders for more understanding of the region in particular about geography, history and the other related disciplines. The restriction of the summer season tours in the region will be tided over introducing winter sports and construction of sports facilities for foreign tourists. It is also desirable that the airport of Yenji will be raised from inner to the international status, so that air traffics between Seoul and Yenji will be directly connected and tourists can save costs and time.
