  • Farmed deer could be susceptible carrier to bovine viral infectious disease. But unfortunately, there has not been an overall study over this subject in Korea so far. Therefore, a study was conducted to see serum antibodies to bovine leukosis, food and mouth disease, bovine viral diarrhea and infectious bovine rhinotracheitis in deer using the sera of farmed deer. As a result, two deer in a farms showed positive in bovine leukosis antibodies, using ELISA. For wild water deer, no antibodies were found for those diseases. As a result, it can be assumed that deer were relatively low rate of exposure to highly contagious disease such as viral bovine infectious disease in Korea. As this study was conducted over limited in number of subject and regions, continued study should be carried out in order to prevent and control the interspecies transmission in the future.

  • The toxic compounds of sorghum stem extracts were isolated by different organic solvents and pH, and characterized and quantified in terms of their inhibition of seed germination and seedling growth in Echinochloa colona(L.) Link and radish(Raphanus sativus L.). Sequential partitioning of stem extract with various organic solvents with increasing polarity showed that all fractions of hexane, ethyl ether, methylene chloride, ethyl acetate, and the aqueous remainder inhibited germination and seedling growth in E. colona. Of the five fractions, the ethyl ether fraction had the greatest inhibitory effect on E. colona. Further separation of the ethyl ether fraction at different pH(pH 2-11) showed that phytotoxic compounds were acidic. The result indicates that the phytotoxin present in the stem extract may be nonpolar and acidic.

  • The objective of this study is to examine how the factors influence each other by determining the appropriate measurement standard in fast food restaurants based on the evaluation of attributes, perceived pricing, value, satisfaction and intention of revisit, and present an effective marketing strategy for fast food restaurants based on the analytical results by patrons and market segmentations. The study surveyed 195 subjects and processed the result using SPSS for Win. V. 12.0. For statistical analysis, Frequency, Factor Analysis, Reliability Analysis, and Regression Analysis were put into operation. As a result of the Factor Analysis of the evaluation of attributes, 3 factors have been extracted. The results showed that restaurant attribution evaluation had a positive effect on the perceived value($R^2adj=0.357$, p=0.000), satisfaction($R^2adj=0.346$, p=0.000) and intent of revisiting($R^2adj=0.389$, p=0.000); perceived pricing had a positive affect on the perceived value($R^2adj=0.464$, p=0.000), satisfaction($R^2adj=0.113$, p=0.000) and intention of revisit($R^2adj=0.276$, p=0.000); perceived value had a positive affect on satis-faction($R^2adj=0.327$, p=0.000) and intention of revisit($R^2adj=0.515$, p=0.000); and satisfaction had a positive affect on intention of revisit($R^2adj=0.442$, p=0.000).

  • Background: The root of Peucedanum japonicum Thunb., a perennial herb found in Japan, the Philippines, China, and Korea, is used as an analgesic. In a previous study, sec-O-glucosylhamaudol (SOG) showed an analgesic effect. This study was performed to examine the antinociceptive effect of intrathecal SOG in the formalin test. Methods: Male Sprague-Dawley rats were implanted with an intrathecal catheter. Rats were randomly treated with a vehicle and SOG ($10{\mu}g$, $30{\mu}g$, $60{\mu}g$, and $100{\mu}g$) before formalin injection. Five percent formalin was injected into the hind-paw, and a biphasic reaction followed, consisting of flinching and licking behaviors (phase 1, 0-10 min; phase 2, 10-60 min). Naloxone was injected 10 min before administration of SOG $100{\mu}g$ to evaluate the involvement of SOG with an opioid receptor. Dose-responsiveness and ED50 values were calculated. Results: Intrathecal SOG showed a significant reduction of the flinching responses at both phases in a dose-dependent manner. Significant effects were showed from the dose of $30{\mu}g$ and maximum effects were achieved at a dose of $100{\mu}g$ in both phases. The ED50 value (95% confidence intervals) of intrathecal SOG was 30.3 $(25.8-35.5){\mu}g$ during phase 1, and 48.0 (41.4-55.7) during phase 2. The antinociceptive effects of SOG ($100{\mu}g$) were significantly reverted at both phases of the formalin test by naloxone. Conclusions: These results demonstrate that intrathecal SOG has a very strong antinociceptive effect in the formalin test and it seems the effect is related to an opioid receptor.

  • This study was designed to determine anxiety factors and levels of anxiety of foreign industrial workers. One hundred and seventy five workers were researched who were working in Guro Working Complex, Ansan City and Sungnam City Working Complex asking 60 questionnaires from Feb. 25, 1996 to April 12, 1996. The results were as follows ; 1. The 30.3% of foreign workers were from Nepal. 17.7% from Bangladesh 10.9% from Srilanka, 14.9% from Philippines, 1.1% from Ghana. 80% of foreign workers were male, 77.7% were single and most of then were in the age from 25 to 34. 37.1% of foreign workers had not lived in Korea less than 12 months, 58.8% graduated from college, 33.7% from highschool, and more than half lived in a dormitory. 2. On the anxiety level related to subject workers' general characteristics, the workers level from Nepal recorded the highest point 2.70 statistically showing a significant difference(P=0.0003). On the physical anxiety level, the workers from Nepal recorded a significantly low point comparing with Jamaica, Burma, Vietnam and Nigeria(P=0.01). 3. Emotional anxiety level marked the highest on the workers living as a tenant comparing with the workers in dormitory. 4. On anxiety factors, the emotional anxiety recoded the highest, the social anxiety and the somatic anxiety. 5. On the relation between the anxiety factor, the somatic anxiety factor had a relation with emotional, environmental, and occupational factors and on the other relation between the anxiety factor and emotional factor had a relation with environmental, social, cultural factors. Moreover, the environmental factor had a relation with the cultural factor, social factor had a relation with the cultural factor, and cultural factor was related to the occupational factor.

  • Surrounded by powerful states, Korean maritime and airspace jurisdiction is constantly exposed to intrusions by its neighbors. Korean government has been, however, exercising significant degree of moderation in response to the occasions. This is where my research starts off: why does Korean government implement only mild measures, which sometimes seem to be insufficient, to infringements on maritime and airspace jurisdiction? I found the answer from the principles and rules of international law: to promote peace and prosperity of the international community, it placed limitations on state rights and prohibited use of force. This point will be elaborated in the paper by examining the contents of restriction and the history of the relevant principles. In the second part of the paper, I explore what strategy could be employed by a state to protect its jurisdiction under present international legal regime. Interestingly, international law, which restricts state jurisdiction, at the same time provides opportunities for lesser powers to protect their state jurisdiction. In the meantime, diplomatic efforts are required. I offer examples of Norway and Philippines, who successfully upheld their arguments against powerful states via international legal regime.

  • The purpose of this study was to suggest an educational direction to aid in formulating a dietary life that is suited to Korea's multicultural families. This was achieved by analyzing the dietary life of immigrant women from multicultural families in Daegu. The study was carried out with 94 immigrant women form multicultural families who were served by public health center A (20 women), public health center B (47 women) and public health center C (27 women). Their home countries were China (55.3%), Vietnam (37.2%), Philippines (3.2%), Japan (2.1%), Uzbekistan (1.1%) and Thailand (1.1%). When the scores of their dietary balance were compared on the basis of the time they have been in Korea (Less than 1 year, 1~3 years, more than 3 years), we found that the score of immigrant women who stayed for less than 1 year was higher than those who stayed for more than 3 years (p<0.05) in terms of their intake of meats, fishes, potato, calcium, and carbohydrate. When subjects were asked about Korean food they wanted to learn how to cook, 30 different types of food were selected and 95.5% of the respondents wanted to learn in detail how to cook Korean food. The place most suitable for them to learn cooking was college (30.3%), while the house of their husband (2.2%) was lowest. Therefore, it seems that a college, public health center or welfare center are good places for immigrant women from multicultural families to participate in an education program that is designed to teach them how to cook Korean food.

  • This study aimed to investigate the current state and trends of health literacy research conducted on female marriage immigrant in South Korea over the past 10 years. A total of 107 related studies were searched through the web database, and 10 of them that met the inclusion criteria were finally analyzed. Most of the studies conducted in the healthcare fields such as nursing. Of the 9 studies were descriptive study, and there were no intervention studies. Most of studies involving women from main country of origin such as Vietnam, China, and the Philippines, and many studies conducted convenience sampling of less than 200 subjects from some regions for reasons such as accessibility. As a tool for measuring health literacy, KHLAT was most frequently used. For future research, collaborative research with healthcare fields and other fields through interdisciplinary interaction is necessary, and a circumstance in which field workers actively participate in research should be prepared. In addition, further studies including larger sample and community-based intervention improve health literacy are needed. Finally, efforts to improve the methodological consistency in the application of health literacy tools and to develop standardized instruments are required.

  • To better understand the exact nature of the major toxic compound responsible for phytotoxicity of sorghum stem, the most toxic compound from the stem extract was isolated by rapid chromatography and subsequently purified by thin-layer chromatography(TLC) and high pressure liquid chromatography(HPLC). Of the eight fractions isolated by rapid chromatography, the fraction with solvent combinations of butanol (8) : acetic acid (1) : water (1) had the highest toxicity. Further separation of the fraction by TLC in a solvent mixture of butanol (24) : acetic acid (16.4) : water (7) : propanol (1) showed that the spot with an $R_f$ 0.71 had one major peak with retention time of 20.40 minutes. Upon subjecting gas chromatography and the HPLC fraction to the mass spectrometry, the toxic compound is probably one of the four compounds ; 1-methyl-1-(2-propynyl)-hydrazine, 1-aziridineethanol, 5-chloro-2-pentanone, and 2-(methylseleno)-ethanamine.

  • Insertion sequence IS1112 is a repetitive element with a relatively high number of copies in Xanthomonas oryzae pv. oryzae (Xoo), the causal agent of bacterial blight of rice (Oryza sativa L.). Three new loci of IS1112 were identified in seven Chinese strains of Xoo using a single oligonucleotide primer J3; 5'-GCTCA GGTCAGGTGGCCTGG-3' by insertion-sequence-based polymerase chain reaction (IS-PCR). Among the three new loci of IS1112, two were located in the open-reading frame region of genes fhuA and cirA, which encode TonB-dependent receptors, and the third in ISXo2, another type of insertion sequence in Xoo genome. Three variants of IS1112 were identified in those three loci based on their sequence similarities: two were identical to IS1112a and IS1112b, reported in strain PXO86 from the Philippines, while the third was a new member of IS1112, defined as IS1112d. Inserting IS1112 in gene fhuA caused three bases, GGT, to be duplicated at the target site, but inserting it in gene cirA did not cause any duplication in the target site. The diversity of IS1112 sequence and insertion loci in Xoo genome and their potential effects are discussed.
