Purpose : This study aims at analyzing perception of death anxiety among juniors and seniors majoring in emergency medical technology to provide data which can contribute to curricular design associated with death that meets characteristics of the students majoring in emergency medical technology as pre-service emergency medical technicians. Methods : This study was conducted with 210 students as juniors or seniors majoring in emergency medical technology at four colleges in some regions(Yeongnam district), finally using 177 copies for data processing. Data collection was carried out from April 11 through May 16, 2008, Analysis was performed using frequency analysis, t-test, and ANOVA. Statistical processing was implemented using an SPSS WIN 15.0 program. Results: 1. 83.6% of students majoring in emergency medical technology had no experience in getting learning about death. 58.7% were afraid of death 'because they would be sad to be separated from things they loved,' 2. The general degree of death anxiety measured in the four-point scale was 2.54(.33). 3. As for differences in death anxiety among students majoring in emergency medical technology by grades, seniors(2.64) showed a lower score for anxiety than juniors(2.74) in terms of 'anxiety about others' death.' 4. As for differences in death anxiety among students majoring in emergency medical technology by gender, female students(2.64) showed a higher degree of death anxiety than males students(2.44), Conclusion : It is necessary to develop education and programs associated with death anxiety in order to reduce fear and anxiety about death and accept one's own death in a positive way through patients in imminent death.
The actiniarian sea anemone, Entacmaea quadricolor, and the scleractinian coral, Alveopora japonica, host symbiotic dinoflagellates belonging to the genus Symbiodinium (Freudenthal). We studied the host-symbiont specificity of these two anthozoan hosts in the northwestern Pacific Ocean. Symbionts within the two hosts were identified using partial large subunit (LSU) ribosomal DNA (rDNA) and complete internal transcribed spacers (ITS) 1 rDNA regions. The host, E. quadricolor, was identified using the partial LSU rDNA molecular marker. Genetic analysis showed that E. quadricolor only harbors dinoflagellates belonging to subclade C1/3 of the genus Symbiodinium. Moreover, no genetic variation was detected among the symbionts of E. quadricolor within the study region (Korea and Japan), even though the two distant sites were separated by more than 1000 km, at collection depths of 1 m in shallow and 13-16 m in deep water. Whilst scleractinian corals host multiple Symbiodinium clades in tropical waters, A. japonica, sampled over a wide geographical range (800 km) within the study region, only hosts Symbiodinium sp. clade F3. The high specificity of endosymbionts in E. quadricolor and A. japonica within the northwestern Pacific Ocean could be accounted for because symbiotic dinoflagellates within the host anemones appear to be acquired maternally, and the Kuroshio Current might affect the marine biota of the northwestern Pacific. However, the consistency of the symbiotic relationships between these two anthozoan hosts and their endosymbionts could change after climate change, so this symbiotic specificity should be monitored.
The world dairy industry has been driving their dairy policy on the basis of the self-supportihg principle. With progressing the GATT negotiation, the objective production amount has been reduced to maintain the optimum level, which decreasing the extra supply and over-stock before the U.R talks. The Oceania countries, where has the price competition capability, are continually increasing the milk production amount. Even through the USA is trying to increase their production amount with new export policy, the U.S.S.R collapse-down caused to decrease the milk production in world-wide basis. Because the U.S.S.R produced the highest amount of milk in the world. Moreover Europe Union countries, which recorded the half amount of dairy products in the world was decreasing their milk production. Therefore, about 4% of shortage is encountering at major dairy production countries in the standpoint of supply and demand. The drastic increasement of foreign dairy product import affects the domestic dairy industry with raw milk replacement and new dairy food demands creation since 1995, the initial period of free import system. Now, the domestic dairy industry are facing the inevitable problems such as the correction of producting and processing system. First of all, our dairy industry should resettle down the dairy production structure on the basis of self-supply of raw milk and offer the accurate dairy food informations. We still need to improve the raw milk quality. Also, more efforts are needed to have proper raw milk price policy. General domestic policies including the settlement of raw milk supply and demand, the reliability of inspection system in raw milk, ideal raw milk price system, centralization of raw milk collection, specially separated dairy organization should be improved legally in our dairy industry.
Five cases of Diphyllobothrium latum infection were proved by collection of worms after treatment with bithionol, niclosamide or praziquantel, during 1975~1983. The patients were 4 males and one female aged 10~64 years residing in Seoul or Wando-gun, Chollanam-do, Korea. All of them remembered the history of eating several kinds of raw marine fish and 2 persons said they ate the raw mesh of perch, Lateolabrax japcnicus. Three amcnE them experienced abdominal pain, 2 natural discharge of a chain of segments, but none revealed any sign of anemia. The average egg size in stool varied $59~67{\times}41~48{\mu\textrm{m}}$ according to cases. The eggs were characterised by ovoid to elliptical shape, terminal operculum, and distinct abopercular protuberance. One naturally discharged segment (30cm) and 4 complete strobilae (320~680cm) with scolices obtained after treatments were examined. The morphological characters of proglottids such as rosette-form uterus with 3~6 loops, vaginal pore included in the cirrus sac, separated seminal vesicle from cirrus sac, etc. were all compatible with D. latum. These are the 7th~11th cases of D. latum infection proved by worms in Korea.
A survey of middle school students and teachers in Mokpo city has been done to understand the perception of environment of students and the present situation of environmental education in middle school. Only 2 of the 14 middle schools have chosen the environmental education course as a required subject. The majority of middle-school students in Mokpo city have learned the environmental education as a subordinate course included in the other subjects such as science, social science or technology. The environmental education in school has been done mostly through non-subject activities such as club activity, group work etc. The survey shows that almost all students think the environmental pollution is serious problem(83% of respondents) and they are especially interested in separate garbage collection(72%) and environmental conservation activity(63.9%) to protect the environment. The concerns about the environmental problems of students(57.7%) has increased after environmental education regardless educational methods or subjects. The students and teachers think that environmental education in school has not been carried out enough and almost all of them(68.4% of students, 97.5% of teachers) agree that the environmental education should be done as an independent subject. In order to more practical and effective environmental education, many opportunities to experience environmental conservation activities should be given during the environmental education course and the environmental education should be separated from other subjects to be taught independently. Moreover, it might be necessary to increase proportion of teachers in environmental disciplines and to develop various teaching methods.
Two cases of human infection by adult Spirometra erinacei were proved by collection of worms in Korea. The patients were 24 and 21-year old males residing in a mountainous village in Kangwon-do. They had the clinical complaints of abdominal pain and epigastric discomfort, revealing the diphyllobothriid eggs, $53~59{\times}37-42{\mu}m$ in size, in their stools. They were treated with 500 mg atabrine and purgated with magnesium salts, and 3~4 hours later several chains of tapeworm segments were recovered from the diarrheal stools. The recovered worms revealed the morphological characteristics of spiral-form or coiled uteri, separated vaginal opening from the cirrus sac, incorporated seminal vesicle into the cirrus sac, distribution of testes at the junction between proglottides, asymmetrical eggs with one pointed eggs, etc. and were identified as Spirometra erinacei (Rudolphi, 1819). The cases had the history of eating raw flesh of the snakes and these are considered the source of infection.
This work focuses on the analysis of bioaerosols in the atmosphere at higher altitudes over Noto Peninsula, Japan. We carried out direct sampling via aircraft, separated cultures, and identified present isolates. Atmospheric bioaerosols at higher altitudes were collected using a Cessna 404 aircraft for an hour at an altitude of 3,500 m over the Noto Peninsula. The aircraft-based direct sampling system was devised to improve upon the system of balloon-based sampling. In order to examine pre-existing microorganism contamination on the surface of the aircraft body, bioaerosol sampling was carried out just before takeoff using the same method as atmospheric sampling. Identification was carried out by a homology search for 16S or 18S rDNA isolate sequences in DNA databases (GenBank). Isolate sampling just before takeoff revealed Stretpomyces sp., Micrococcus sp., and Cladosporium sp. One additional strain, Bacillus sp., was isolated from the sample after bioaerosol collection at high altitude. As the microorganism contamination on the aircraft body before takeoff differed from that while in the air, the presence of additional, higher atmosphere-based microorganisms was confirmed. It was found that Bacillus sp. was floating at an altitude of 3,500 m over Noto Peninsula.
The purpose of the present study was to produce live offspring from in vitro fertilized goat embryos. Oocytes were collected from abattoir ovaries and kept in oocyte collection medium. Oocytes were washed 4-5 times with maturation medium containing medium-199 with 5 ${\mu}g/ml$ FSH, 100 ${\mu}g/ml$ LH, 1 ${\mu}g/ml$ estradiol-$17{\beta}$ 50 ${\mu}g/ml$ gentamycin, 10% inactivated estrus goat serum, and 3% BSA (fatty acid free). Oocytes were placed in 100 ${\mu}l$ drops of maturation medium containing granulosa cell monolayer and incubated in a 5% $CO_2$ incubator at $38.5^{\circ}C$ for 27 h. For capacitation of spermatozoa fresh semen was processed and mixed in 3 ml fertilization TALP medium containing 50 ${\mu}g/ml$ heparin and kept in the above incubator for 2 h. The capacitated spermatozoa were coincubated with matured oocytes for fertilization. Cleaved embryos were separated and cultured in embryo development medium with oviductal cells and 494 embryos were produced. Recipient goats were synchronized with two injections of 15 mg $PGF_{{2}{\alpha}}$/goat 10 days apart. Eighty early stage embryos were transferred into the uterotubal junction of 14 surrogate mothers using laparoscopy techniques. One recipient delivered twin kids, whereas another two recipients each.delivered a single kid The parentage of these kids was evaluated using highly polymorphic co-dominant microsatellites markers. From the present study, it was concluded that live goat kids can be produced from in vitro matured and fertilized goat embryos, to the best of our knowledge for the first time in India.

In this study, the treatment flow of the recyclables(paper, plastic, metal, etc.) collected and separated from MSW was investigated throughout entire phase from separation and collection to final disposal. Based on the site survey, most recyclables came into six material recovery facilities were comparatively managed well. However, some of recyclables showed irrelatively transportation flow. Because the main income source of the recyclables transportation companies is profit margin between treatment and transportation cost based on economics only therefore, it occurs an unnecessary route and long distance transportation while going to final destination. This unreasonable system should be a serious problem relating establishment of the resource recycling system. As a result of this study, in order to establish the reasonably resource recycling system, recycling center including material recovery facility has to manage the recyclables generated in close range preferentially. Also integrated its treatment system over a wide area will need to be considered as a basic step for the reasonable reasonably resource recycling system.
The objectives of this study are to select and analyze unpublished wedding dresses in the 19th century, to investigate the design characteristics and making techniques of Victorian wedding dresses, and to examine the correlation between the wedding dress style and the fashion style in those days and the influence of the wedding dress style on contemporary's styles. The materials of this study were 9 wedding dresses owned by the Historical Costume and Textile Collection at the University of Connecticut in USA. The dresses were made during the mid and late Victorian Age. As for silhouette, the bustle style was popular in the 1870s and 1880s, and the hourglass style in the 1890s, and different from contemporary dresses there were no big differences in structural pattern and details between ordinary dresses and wedding dresses. In addition, colored wedding dresses were used until the mid and late Victorian Age, but since the wedding ceremony of Queen Victoria in 1840, white wedding dress was widely accepted and settled as the tradition of today's wedding dresses. While the Western dress style had been basically a one piece style, there appeared simple two piece designs in which the upper garment was separated from the lower one, from the mid Victorian Age. This is considered the reflection of those days' pragmatic social trend in dress style. It seems around 1875 when asymmetric design was first introduced in the Western dress style, which had been mostly symmetric. The asymmetric style that pursued atypical beauty, though not common during the late Victorian Age, shows a change in the typical Western dress style. With regard to dress making techniques, sewing machines were distributed widely during the early Victorian Age but they were not used in all parts of dress. Most of details and trimming works were done manually and some parts were attached and detached by hand sewing. In addition, not like today, there were no generalized rules of making such as the form of closings and composition.
