  • The purpose of this study was to investigate the factors influencing health promoting behavior and satisfaction of life in female undergraduate students, to provide the basic data for health promoting intervention in order to improve satisfaction of life. The subjects of this study were 345 female undergraduate students living in Jecheon city who were selected by convenience sampling. The data was collected through self-reported questionnaires from Oct. 2 to Dec. 20, 2001. Research instruments used in this study were the health promoting lifestyle profile developed by Walker et al(1987), satisfaction of life developed by Pavot and Diener(1993), perceived health status by Lawston et al(1982), self-esteem by Rosenberg(1965), self-efficacy by Becker et al(1993), health locus of control by Wallston et al(1978). The data was analyzed by using descriptive statistics, pearson correlation coefficient, stepwise multiple regression with SPSS/Win program. The results of this study were as follows; 1) The mean score of health promoting behavior was 2.31 point out of 4. Among the sub-levels of health promoting behavior, the order of importance was the following self-actualization(2.76), interpersonal support(2.75), stress management(2.31), nutrition(2.06), health responsibility(1.83), exercise(1.76). The mean score of satisfaction of life was 4.11 point out of 7. 2) The health promoting behavior showed significant positive correlation with perceived health status, self-esteem, self-efficacy, internal health locus of control, powerful others health locus of control. The satisfaction of life showed significant positive correlation with perceived health status, self-esteem, self-efficacy, internal health locus of control, health promoting behavior. 3) In the relationship between general characteristics and health promoting behavior, there was a significant difference in majors(F=8.50, p=.000). In the relationship between general characteristics and satisfaction of life were significant differences in a grades(F=2.67, p=.04) and economic status of parents(F=8.59, p=.000) 4) The most powerful predictor of health promoting behavior was self-efficacy. A combination of self-efficacy, self-esteem and powerful others health locus of control accounted for 34.7% of the variance in health promoting behavior. The most powerful predictor of satisfaction of life was self-esteem. A combination of self-esteem, health promoting behavior, perceived health status, economic status of parents and grade accounted for 34.0% of the variance in satisfaction of life. In conclusion, we need a health promotion program focusing on exercise, health responsibility and nursing strategies enhancing self-efficacy and self-esteem should be developed to promote a healthy lifestyle and satisfaction of life in female college students.

  • Surgical-orthodontic treatment is an increasingly more common dental procedure whose unique psycho-social or psychological feature has not been fairly quantified objectively. Since the treatment of a surgical-orthodontic (or orthodontic) patient is part science and part art, a subjective recognition of a patient about his or her own treatment may be more important than technical success during and after treatment. Therefore, the knowledge of the patient's underlying psychological status could be useful in the prediction of patient's response to surgical-orthodontic (or orthodontic) treatment. The purpose of this study was to investigate and evaluate the psychological difference between conventional orthodontic patient and surgical-orthodontic patient by using locus of control (LOC) examination. Locus of control scale has been proven to be extremely useful in the prediction of a variety of human behaviors. Two types of locus of control data (I-score, Internal locus of control score : I-score, External locus of control score) were obtained for 42 surgical-orthodontic patients and randomly selected 42 conventional orthodontic patients (as a control group) matched for age and gender. No statistically significant difference was observed in the scale of internal and external locus of control between the groups of surgical-orthodontic patients and conventional orthodontic patients. However, in the group of surgical-orthodontic patients, males showed lower E-score (external locus of control score, higher internal locus of control tendency) than females. The results of this study suggested that the psychological background of surgical-orthodontic patients, in contrast with that of cosmetic surgery patients, has a similar disposition with that of orthodontic patients.

  • Sarabi cows (n = 136) from the Sarabi Breeding Station were genotyped at bovine lymphocyte antigen (BoLA)-DRB3.2 locus by a genotyping system that used the polymerase chain reaction and restriction fragment length polymorphism. Genomic DNA was extracted from whole blood samples. A two-step polymerase chain reaction was carried out in order to amplify a 284 base-pair fragment of target gene. Nested-PCR products were digested with three restriction endonuclease enzymes RsaI, BstYI and HaeIII. Digested fragments were analyzed by polyacrylamide gel electrophoresis. Twenty-six BoLA-DRB3.2 alleles were identified with frequencies ranging from 0.4 to 15.1%. Six new allele types observed in this study have not been reported previously. Identified alleles include: BoLA-DRB3.$2^*1$, $^*2$, $^*4$, $^*6$, $^*8$, $^*12$, $^*13$, $^*14$, $^*15$, $^*16$, $^*17$, $^*23$, $^*24$, $^*25$, $^*28$, $^*32$, $^*34$, $^*35$, $^*36$, $^*37$, $^*42$, $^*46$, $^*51$, $^*kba$, $^*laa$ and $^*vaa$. Their frequencies were found to be 0.4, 0.4, 0.7, 11.4, 1.1, 1.8, 2.9, 2.2, 4.4, 9.6, 1.1, 13.6, 0.4, 0.4, 1.1, 0.7, 0.4, 6.2, 2.2, 3.7, 1.1, 7.7, 1.5, 15.1, 2.6 and 7.3% respectively. The six most frequent alleles (DRB3.2 $^*6$, $^*16$, $^*23$, $^*46$, $^*kba$ and $^*vaa$) accounted for 64.7% of the alleles in the population of this herd. Numerous studies on this locus, covering different breeds, has revealed the existence of various alleles in this locus, and new investigations have introduced novel alleles. With respect to the high number of the observed alleles in this survey and the novelty of some alleles with no previous record of reporting, it is plausible to conclude that the BoLA-DRB3.2 locus is highly polymorphic in Iranian native Sarabi cows.

  • This study presents results of electro-phoretically detectable isozyme variation in Crossing Block (CB) lines of two-rowed barley maintained by the National Crop Experiment Station. The specific objectives were to determine allelic frequencies at the four Est loci(Est1, Est2, Est4, and Est5) and their distribution over 380CB lines of two-rowed barley. A total of 17 alleles were detected over the four Est loci in these lines. There were 4 alleles (Pr, Al, Ca, and Af at the Est1 locus and their frequencies were 69.7, 1.1, 28.4, and 0.8%, respectively. At the Est2 locus, 5 different alleles (Dr, Fr, Sp, Un and a recessive null allele) were detected and their frequencies were 2.9,84.5,0.5,2.1, and 10%, respectively. four alleles (Nz, Su, At, and null were detected at the Est4 locus and the allelic frequency of Su was about 84%. Four alleles(Mi, Pi, Te, and a null allele(od)) were detected at the Est5 locus and their frequencies were 34.2, 61.0, 2.4, and 2.4%, respectively. Based on the allelic frequencies over the four Est loci, 380 CB lines were classified into 25 genotypes. The most frequent genotypes were G1(Pr-Fr-Su-Mi) and G2(Pr-Fr-Su-Pi), and their frequencies were 28.1 and 39.5%, respectively. The frequencies of other genotypes were less than 10%.

  • To analyze the linkage relationships among molecular markers recently reported to be linked to onion (Allium cepa L.) Ms, a restorer-of-fertility locus, in onion (Allium cepa L.), three single nucleotide polymorphism markers were converted into cleaved amplified polymorphic sequence (CAPS) markers based on onion transcriptome sequences and the rice genome database. Analysis of the recombinants selected from 4,273 segregating plants using CAPS and other linked markers demonstrated the jnurf13 and jnurf610 markers to perfectly co-segregate with the Ms locus. In contrast to jnurf13, the jnurf610 marker was not in perfect linkage disequilibrium with the Ms locus in diverse breeding lines. Thus, the jnurf13 marker and the marker for identification of cytoplasm types were utilized to enhance the efficiency of onion breeding through four applications. First, 89 maintainer lines containing the normal cytoplasm and homozygous recessive Ms genotypes were successfully identified from 100 breeding lines. Second, these two molecular markers were used to analyze the main sources of male-fertile contaminants frequently found in the male-sterile parental lines during F1 hybrid seed production. The majority of the contaminants contained heterozygous Ms genotypes, indicating that pollen grains harboring the dominant Ms genotype may have been introduced during propagation of the maintainer lines. Therefore, the genetic purity of the two maintainer lines was analyzed in the third application, and the results showed that both maintainer lines contained 13-21% off-types. Finally, the two markers were used to increase the seed yield potentials of two open-pollinated varieties containing sterile cytoplasms by removing the plants harboring homozygous recessive and heterozygous Ms genotypes.

  • Purpose : This study can provide various implications for the franchisors to expand activities related to franchise support or to develop andoperate an education program for foodservice franchise owners. Research design, data, and methodology : For those purpose, first, the literatureand literature related to the competency of domestic franchise owner were collected and reviewed through the Korea Education and Research Information Service (RISS). Second, the questionnaire was prepared based on the theoretical basis prepared through previous studies. Based onthe foodservice franchise owner's competency model presented by Kim & Lee (2019b), 13 franchise owner's competencies were marked with both 'What is' levels and 'What should be' levels. Therefore, the total questionnaire consists of 26 questions. Third, questionnaires were distributed and collected. This study used data from 55 surveys which were gathered from foodservice franchise owners in Seongnam-si. SPSS 25.0 was used to analyze the collected survey data. Descriptive and frequency analysis were conducted to analyze the demographic characteristics of the study subjects. Next, we conduct a t-test to analyze the difference between the level of 'What is' competencies by the franchise owners and the level of 'What should be' competencies. Descriptive statistics were used to derive the priorities of the 'What should be' competencies. The Locus for Focus model was used to derive the priorities of the required competencies. Result : Four competencies of team leadership, teamwork and cooperation, customer service, technical·professional·managerial expertise were found to be the first to be developed. Conclusions : The conclusions of this study are as follows. First, teamwork and cooperation competnecy, and team leadership competency, which are derived from the core competencies of foodservice franchise owners, are among the leadership competencies required as managers of organizations. Second, customer service competency and ttechnical·professional·managerial expertise competency derived from the core competencies of restaurant franchise owners belong to the job competencies. Third, the results of this study suggest that the foodservice franchisors will be able that will serve as a baseline to support the foodservice franchisors and franchise owners for sustainable mutual growth by encouraging their will and encouraging them to create results.

  • The effect of aqua-acupuncture of total saponin on the recovery of liver function in -intoxicated rats was exemined. Rats were divided into normal, control and three experimental groups (As-I group : aqua-acupuncture of saline to Gansu locus and Aa-III group : aqua-a-cupuncture of total saponin to blank locus at the thigh). Changes of some serum biochemical parameters (ALT, AST and ALP, total protein and albumin, and albumin/globulin (A/G) ratio) were determined. Serum ALT activities were increased by $CCI_{4}$T and decreased in all aqua-acupuncture groups compared with the control group. Aa-I group showed significant decrease of ALT activities on the 2nd (P<0.05) and 3rd (P<0.05) day, respectively. Aa-II group showed significant decrease on the 3rd day (P<0.05) day. Serum AST activities were increased by $CCI_{4}$T and decreased in all apua-acupuncture groups compared with the control group. Aa-I group showed significant decrease on the 1st (P<0.05), 2nd (P<0.001) and 3rd (P<0.001) day, respectively. Aa-II group showed significant decrease on the 3rd (P<0.001) day. Aa-III group showed significant decrese on the 1st (P<0.05) and 3rd (P<0.001) day, respectrvely. Serum ALP activities were increased by $CCI_{4}$T and decreased in all aqua-a-cupuncture groups compared with the control group. Aa-I group showed significant decrease on the 3rd (P<0.01) day. Total protein, albumin and A/G ratio were decreased by $CCI_{4}$T and increased in all aqua-acupuncture groups compared with control group. Aa-I group showed significant increase only on the 3rd day in albumin (P<0.01). It was thought that the aqua-acupuncture of total saponin to Gansu locus was effective on the recovery of liver function in $CCI_{4}$T-intoxicated rats.

  • Mating type of Lentinula edodes is determined by two unlinked genetic loci, A and B. To better understand mating behavior of L. edodes, we investigated variations in mating type genes in129 dikaryotic strains collected from East Asia. Through sequence analysis of A locus, we discovered that hypervariable region spanning N-term of HD2-intergenic region-N-term of HD1 could represent A mating type. Mating and hypervariable region analyses revealed 70 unique A mating types: 27 from 98 cultivated strains, 53 from 31 wild strains, and 10 commonly found. It was also revealed that only a few A mating type alleles such as A1, A4, A5, and A7 were prevalent in cultivated strains. Contrarily, A mating type in wild strains was highly diverse: 23 unique A alleles were discovered in small mountainous area in Korean peninsula, suggesting rapid evolution of A mating type in nature. The B locus was assessed by allelic variations in pheromone (PHB) and pheromone receptor (RCB) pairs which constituted subloci Ba and Bb. Sequence analyses and mating assay revealed 5 alleles of RCB1 with 9 associated PHBs in Ba sublocus and 3 alleles of RCB2 with 5 associated PHBs in Bb sublocus. Each RCB was primarily associated with two PHBs. Each PHB-RCB pair was always discovered as a distinct unit. This allowed us to propose 15 B mating types via combinations of five Ba and three Bb subloci. Further investigation on 129 strains confirmed that the B locus, unlike the A locus, was indeed restricted to 15 mating types. Thus, the total number of mating types became 1,050 in L. edodes through a combination of 70 A and 15 B. This number will further increase because of rapid diversification of A mating type. Our findings provide a comprehensive and practical knowledge on mating behaviors of L. edodes.

  • This study was conducted to explore the relationship between locus of control and health belief. the life style of gastric cancer patients. The subjects of this study were 40 of the early gastric cancer and 90 of the advanced gastric cancer who first visiting patient to general surgery out patient department of Chungnam University Hospital for operation. The data was collected with structured questionnaire from July. 1998 to Feb. 1999 The tool were Moon's Health Belief Scale and Multiple Locus of Control of Wallston. Wallston, DeVellis. The data was analysed by SAS program using frequency, $X^2$-test, Pearson's correlation coefficient, ANOVA. Scheffe-test, t-test. The results were as follows 1. 30.8% of subjects were early gastric cancer anf 69.2% were advanced gastric cancer. The subject knowing about diagnosis was 83.1%. 16.9% did'nt know about diagnosis. 2. The correlationship between Health belief and Locus of control of subjects was not supported. 3. There was statistically no difference of life style between early and advanced gastric cancer patients. 4. There were statistically significant differences in perceived sensitivity according to weight. educational level. and birth order, in perceived barrier according to educational level. and in perceived severity according to occupation among demographic characteristics of study subjects. From above results. health professional has to educate general population to detect gastric cancer early to improve survival rate because early gastric cancer is high in survival rate, and to prevent recurrence and to maintain continuing healthy status. In the future, gastroscopy also has to expand to detect early. For there was no difference in life style between early and advanced gastric cancer. carcinogen related to diet should be emphasized through education. The perceived benefit among health belief model was not supported in this study therefore further study and comparison between gastric cancer and normal population are needed.
