The purpose of this study was the reaching test of restorative glass according to composition. Mixtures of SrF₂, CaF₂and SiO₂were fused in platinum crucible. The glasses were ground and fraction which passed through a 400 mesh (38㎛) sieve were collected. The powder specimens were analyzed by a DTA and XRD. Then powder specimen were inserted to D. I. water with various of dissolution time and composition at 37℃. Fluoride ion, cation release, solubility, and pH change were estimated. It was clear that the glasses were formed except S0.65. In S0.40, Tg, Ts, and Tc were 630, 672, and 813℃ respectively. In initial 0.5 hrs., amounts of released fluoride ion and cation were about 90% of total released amounts and released rate was decreased with dissolution time. Amount of released fluoride ion and cation were increased with decreasing SiO₂ in glass filler. And released rate was decreased rapidly by adding CaF₂. This was caused by structural variation in glass filler. Solubility was similar tendency with ion released. The pH of D.I. water was 4.5. But in intial 0.5 hrs., pH was 8.2∼9.8., and decreased according to dissolution time. This is caused by ionic changing with cation and H* ion.

Gastrointestinal stromal tumor (GIST) is the most common non-epithelial neoplasm arising in the gastrointestinal tract, but this tumor is rarely seen in association with type l neurofibromatosis (NFl) Generally, the majority of GISTs are isolated neoplasm and they are sporadically found in the stomach, but the GISTs in NFl patients are usually multiple and usually found in the small intestine. We report a case of multiple GISTs in the jejunum of a 63-year-old woman diagnosed as NFl accompanied by complication of gastrointestinal bleeding, In this case, Patient had multiple cafe-au lait spots and neurofibroma on skin and had freckling on axilla and groin, and then, we made a diagnosis of NFl. Gastrointestinal bleeding is controlled by resection of multiple GISTs. Generally, only 3-5% of all gastrointestinal bleeding comes from the small bowel. Causes of small intestinal bleeding are angiodysplasia, neoplasm, NSAIDs induced ulcer etc. but, If patients have NFl accompanied by complication of gastrointestinal bleeding, GISTs on small bowel must be considered.

This study is the case study on teachers' experience on curriculum implementation in the school by narrative inquiry. In this study, narrative inquiry is a way of understanding the teachers' experience of implementing and developing the curriculum by telling and retelling the experience of the lives as a teacher. The research questions of this study are summarized as follows; 1. What is the educational meaning of the teachers' experience in implementing the National Curriculum and developing school based curriculum? 2. What is the educational significance of the narrative inquiry on studying the curriculum? To solve these problems, we made use of the narrative inquiry, especially autobiographic writings which are a powerful method of understanding experience. Our excitement and interest on narrative inquiry has its origins in our interest in experience The results of this study show that the teachers' experience of developing and implementing the curriculum has influenced on their identities as teachers. Sometimes, teachers conceal their identity in being placed out of classroom landscape. Teachers' identies that are forming are consequent on their experience in developing and implementing the curriculum. The results give a suggestion in studying teachers' experience of developing and implementing the curriculum by narrative inquiry. The necessity of the understanding of the teachers' experience is acknowledged in curriculum study. When the teachers are the curriculum implementer and the curriculum developer, they feel the school curriculum is more significant for their lives as a teacher in the school. In addition, the result shows that the process of this narrative inquiry can be a useful method applied to the curriculum study for exploring the teachers' experience. In this study, narrative inquiry processes are summarized as follows: 1) selecting the object of field texts (in this study, by the autobiography method). 2) composing the field texts bewaring reductionism and formalism. 3) composing the research texts by the analysis of field texts.

복합섬유의 고속방사에 있어서 섬유구조형성(Ⅱ) : LLDPE/PET 복합의 효과 Effects of LLDPE/PET Bicomponent System

김경효,조현혹,장정대 釜山大學校生産技術硏究所 1997 生産技術硏究所論文集 Vol.53 No.-

sheath-core형 복합섬유를 고속용융방사하여 방사속도에 따른 섬유구조의 변화를 검토하였다. 복합섬유는 폴리에틸렌테레프탈레이트(PET) 및 2종류의 선상 저밀도폴리에틸렌(LLDPE), 즉 융체유동속도(MFR)가 45, 50인 것을 사용하여 LLDPE를 sheath에 PET를 core에 배치하였다 고속방사된 복합섬유중의 각 성분의 구조형성을 복굴절, 광각X선회절 및 열분석 등으로 검토한 결과, PET성분을 단독으로 고속방사한 경우에 비해 LLDPE의 MFR에 상관없이 LLDPE/PET 복합섬유중의 PET성분은 약 1km/min 낮은 방사속도에서 배향결정화가 일어나 PET성분의 섬유구조형성은 촉진되었으며, LLDPE성분의 섬유구조형성은 LLDPE 단독으로 방사한 경우에 비해 억제됨을 확인하였다. High-speed melt spinning of sheath-core type bicomponent fibers was performed and the change of fiber structure with increasing take-up velocity was investigated. Three kinds of polymers, poly(ethylene terephthalate) (PET), linear low-density polyethylene(MFR=45) (LLDPE(45)) and linear low-density polyethylene(MFR=50) (LLDPE(50)), were selected and two sets sheath/core combinations, LLDPE(45)/PET and LLDPE(50)/PET(i.e. sheath/core), were studied. The structure of each component in high-speed spun bicomponent fibers was analyzed through the birefringence, wide-angle X-ray diffraction measurements and DSC thermogram measurements. The development of molecular orientation and the initiating of the orientation-induced crystallization of PET in LLDPE/PET bicomponent fibers occurred at lower take-up velocities regardless of the type of LLDPE as compared to those in the single component spinning. The fiber structure formation of LLDPE component in LLDPE/PET bicomponent fibers was suppressed as compared to that in the single component spinning.

김경영,한동준,신대은,노준,문형윤,임동훈,김철성,박성운 朝鮮大學校 附設 醫學硏究所 2007 The Medical Journal of Chosun University Vol.32 No.3

Purpose: We determined the use of scrotal ultrasonography in the initial diagnosis and management of testicular injuries due to blunt scrotal trauma. Mateiials and Methods: We reviewed 54 patients of scrotal trauma in the last 8 years. Forty patients were evaluated by ultrasonography preoperatively. A heterogeneous echo pattern of the testicular parenchyma with loss of oval shape, contour definition was the basis for diagnosis of testicular rupture. Among them, 33 cases underwent scrotal exploration and 7 cases were managed conservatively. The remaining 14 patients were evaluated only by physical examination, 8 patients of them were explored immediately because of suspicious testicular mpture. The accuracy of ultrasonography were determined by comparing radiographic interpretations with intraoperative findings. Results: Among the 33 patients who were evaluated by ultrasonography and explored immediately, there were 26 suspected testicular ruptures on ultrasonography. Surgical exploration revealed testicular rupture in 23 and simple hematoma in 10. The testicular rupture was correctly diagnosed by ultrasonography in the 22 cases, and there were 4 false-positive and 1 false-negative diagnoses of testicular rupture. The sensivity and specificity for the diagnosis of testicular rupture are 96% and 60%, and the positive and negative predictive values are 85% and 86%, respectively, Conclusions: Scrotal ultrasonography, with the main radiographic finding of a heterogeneous echo pattern of the testicular parenchyma with loss of oval shape, contour definition, is highly sensitive on the diagnosis of testicular rupture. And it increases the salvage rate for testicular rupture with preservation of the testicular function and prevents delayed complications of chronic pain, atrophy and orchiectomy associated with missed testicular rupture.

We analyzed responses from 122 students originally from Busan enrolled in the Busan Studies class. 60.7% of students reported being non-religious; 21.3% were Buddhists; 8.2% were Protestants; and 9% were atholics. The hometowns of the students’ fathers varied: Busan (59% of the students) and Gyeongnam province (29.5%) together accounted for 88.5% of respondents, outstripping Daegu/Gyeongbuk province (6.5%) and Honam/Jeju (4.9%). Their mothers' hometowns were also predominantly Busan (54.1%) and Gyeongnam province (22.1%), totaling 76.2%, though this proportion was lower than that of the hometowns of the students’ fathers. Daegu/Gyeongbuk and Honam/Jeju accounted for 6.5% and 7.4% of the mothers’ hometowns respectively. In response to the question "how many times have you watched professional baseball games?", 33.6% of the respondents answered that they had never watched a game. 22.1% answered that they had watched once, and 11.5% twice, making the proportion of students who had watched games either once or twice 33.6%, the exact same proportion as the percentage of students who had never watched one. Regarding the number of overseas trips respondents had taken, 30.3% answered that they had never traveled abroad; 28.7% had travelled once and 14.8% twice. 61.5% of the students surveyed answered that they had never participated in the Busan International Film Festival (BIFF) and that they had not thought about participating or had not wished to participate in the BIFF in 2017. As for favorite beverages, coffee ranked first (26.2%), cola ranked second (19.7%), followed by sports drinks (14.8%), fruit juices (13.9%), and sprite (12.3%). When asked what kind of food represented Busan best, students chose pork and rice soup the most (36.2%), followed by fish cake (20.9%), wheat noodles (13.6%), mixed-seed sweet pancake (ranking a surprisingly high 6.7%), and scallion pancake (4%). An interesting finding was that students did not think of raw fish as a typically Busan dish. In response to the question of where students would take their friends from other regions to show them the city, the results are as follows: Gwanganli (21.8%), Haeundae (12.5%), Seomyun (6.5%), Centum City (5.4%), Busan International Film Festival (5%) and Gwangan Bridge (4.4%). Regarding the Bus an dialect, 87.7% of the students surveyed said that they use it comfortably and without any hesitation in their daily lives. The amenities that students would like to see in Busan in the future were public parks (11.3%), bungee jumping (10%), theaters (6.1%), extreme sports parks (6.1%), museums (5.4%), indoor baseball parks (5.3%), opera houses (5.2%) and libraries (5.2%). 52.5% of the students surveyed answered that a large shopping mall would help develop their neighborhood. While students’ responses varied on the question of whether Busan people litter, a majority thought littering was less pervasive. A majority of students also believed that people in Busan did not generally cut in line. Responses were found to be generally positive regarding Busan people offering their seats to others, giving others directions and waiting for people to get off first in the elevator. Most students think that people in Busan drive recklessly, with 16.4% “strongly” believing so. More students indicated disagreeing with the statement that ‘people yield when driving.’ There were also more responses of ‘agree’ to the statement that ‘people do not follow traffic rules.’ Overall, students did not believe that people in Busan obey the rules of the road. A majority of students also did not believe that Busan’s streets are clean. The question on whether river water is clean was also dominated by negative responses. Also, the students did not believe that Busan city-goers cleaned up well after themselves. Given that the responses to the previous question were very similar to the question about street cleanliness, it is found that the students believed that the streets are dirty because they are not cleaned well.

重商主義槪念과 重商主義의 本質的 要素

金敬浩,金大來 新羅大學校 1990 論文集 Vol.29 No.-

This paper examines the methodology of mercantilism. For this ① to investigate the concept of mercantilism which has been conventionally accepted and to interpretate its methodological meaning. ② to extract essential elements of mercantile thoughts from mercantilist and later economists' writings. Then ③ from the point of view of methodology to reinterpretate these elements. After this work this paper stresses three major facts as follows. ① Money was invariably the stuff of expression which adopted by mercantilist. Thus it is very important to find what they truly pursued in the name of money. ② In the age of Mercantilism monopoly and regulation was a doctrine of ecomic life. And this was rationalized by national interests. But national interests were always exclusively connected with specific class interest. Thus the conventional concept defined as if mercantilism were for the nation as a whole shall be reconsidered. ③ Also the conventional notion that all the mecantile economic policies were subordinated to the economic state building is not correct. Rather superstructure corresponds to social economic interests. After considering these mentioned above, it is nessary to appreciate mercanlis policies in the process of capitalist development.
