Objective & Methods : In the point of several medical books included 'Internal Classic' and Hyungsang medicine, the writer studied about meridian theory and it's disorders, after adapting to acupuncture and herb medicine. Results : 1. Dr. Jisan explained concretely physiological and pathological meridian appearances with using metaphor about phenomenons of nature and human living. 2. Shapes corresponding to meridian are considered as Yukkyunghyung formed by more or less of vigor and blood, and by tendency of up and down in eyes and nose, and also contained diseases of viscera and characters. 3. The colors connected with meridian are changed according to conditions, and meridian is seen through colors. And then colors is the properties of vital energy and symbol of spirit, that is expressed as aspect of essence, vigor, spirit and blood, as the original color of five viscera, as the colors of four seasons and as the colors of diseases. So the changes of feelings are appeared to meridian flow. 4. The method of examining pulse for meridian disorders is applied to Jisan diagram. Jisan diagram is devised from mutual communication of viscera and connection with inside and outside. It is conjugated widely in clinical examination to be distinguished into Dam-Bangkwang, into diseased part of viscera and into meridian. Also it is conjugated recuperation of diseases. 5. The meridian diseases are appeared all the distributed parts of meridian, especially skin, hair, eyebrow, and the ends of the extremities which are sensitive to stimulus. The causes are the disharmony between vital energy and blood and the discordance of six atmospheric variation. The symptoms are skinny aches, itching and eruption, etc. Conclusions : The acupuncture of Hyungsang medicine which utilizes classification of shapes, examining pulse according to Jisan diagram and demonstration of symptoms, is very effective and required systematical study from now on.

Purpose: This study examined the mood state, activities of daily living, and attitude toward aging in the elderly according to the existence of a spouse and investigated the relation between these factors. Method: The subjects consisted of 190 elderly people, who were classified into two groups: those with and without a spouse. The data was collected from March to December 2004 using a structured questionnaire that included general characteristics, mood states, instrumental activities of daily living (IADL), and an attitude toward aging scale. The collected data was analyzed using the program SPSS, including descriptive statistics, $x^2-test$, ANOVA, Scheff's test, and the Pearson correlation coefficient. Result: 1. There were significant differences between the two groups in mood state (t=-3.349, p=.001), anxiety-depression (t=-3.350, p=.001), and anger (t=p=.003) in the mood state subscales, and in attitude toward aging (t=2.514, p=.013). 2. There was a significant positive correlation between vigor and IADL (r=.253, p=.012) in the elderly with a spouse. 3. When there was a spouse, there was a significant difference according to gender (t=2.587, p=.012) in IADL. Without a spouse, there were significant differences in mood states according to education level (F=3.315, p=.023), in anxiety-depression according to the presence of illness (t=2.156, p=.033), in vigor according to age (F=3.439, p=.020) and education level (F=5.285, p=.002), and in IADL according to monthly income (F=3.322, p=.023) and the presence of illness (t=2.172, p=.032). Conclusion: An individualized approach is needed for elderly people that considers living arrangements and the existence of a spouse.

Glycerol is the cryoprotectant most frequently used to freeze semen in several of species. The objective of the present study was to compare the effect of three different glycerol concentrations (4, 6 or 8%, v/v) on frozen-thawed dog sperm survival rate. Ejaculates from 9 dogs collected by digital manipulation were pooled and assessed by macroscopic and microscopic criteria. Semen was divided into 3 aliquots, which were centrifuged and the sperm pellets rediluted with first Tris-glucose-citric acid extender. After 1 h cooling at $4^{\circ}C$, second extender containing 4, 6 or 8% glycerol was added, respectively. The semen was loaded into 0.25 ml straws and frozen and stored in liquid nitrogen and thawed. Sperm vigor, live:dead spermatozoa ratio using HOS test, and sperm morphology using $Spermac^{(R)}$ stain were evaluated. After thawing, there were no significant differences among groups in vigor, viability and morphology. In conclusion, the three glycerol concentrations (4, 6 or 8%) can be used successfully in cryopreservation of canine semen. Therefore the use of 4% glycerol in the extender has less toxic effect and reduces of freezing injuries.

The purpose of this study was to obtain data on the contribution of job characteristics (work, autonomy, reward, community, fairness, value) towards job burnout (emotional exhaustion, cynicism), job engagement (vigor, dedication, absorption) and turnover intention in school foodservice employees. Typically, 594 school foodservice employees in the Busan area participated in our survey. Workload (${\beta}=-0.512$, p<0.001) had the highest negative influence on emotional exhaustion, whereas reward (${\beta}=-0.216$, p<0.001) and community (${\beta}=-0.214$, p<0.001) had the highest negative influence on cynicism. Community (${\beta}=0.305$, p<0.001) and workload p<0.001) had the highest positive influence on vigor. Community (${\beta}=0.261$, p<0.001) and (${\beta}=0.238$, p<0.001) had the highest positive influence on dedication. (${\beta}=0.287$, p<0.001) and community (${\beta}=0.224$, p<0.001) had the highest positive influence on absorption. Workload (${\beta}=-0.195$, p<0.001) and community (${\beta}=-0.182$, p<0.001) had the highest negative influence on turnover intention. Overall, the results show that job characteristics are very important factors affecting foodservice employee's burnout, engagement, and turnover intention. So should try to reduce the employees' workload and increase the rewards for them along with activating communication among each other.

A study was conducted to determine the phytotoxic effect of mercury on seed germination and seedling growth of an important arid legume tree Albizia lebbeck. The seeds germination and seedling growth performance of A. lebbeck responded differently to mercuric chloride treatment (1 mM, 3 mM, 5 mM and 7 mM) as compared to control. Seed germination of A. lebbeck was significantly (p < 0.05) affected by mercury treatment at 1 mM. Root growth of A. lebbeck was not significantly affected by mercury treatment at 1 mM, and 3 mM. Shoot and root length of A. lebbeck were significantly (p < 0.05) affected by 5 mM concentration of mercury treatment. Increase in concentration of mercury treatment at 5 mM and 7 mM significantly (p < 0.05) reduced seedling dry weight of A. lebbeck. The treatment of mercury at 1 mM decreased high percentage of seed germination (22%), seedling length (10%), root length (21.85%) and seedling dry weight (9%). Highest decrease in seed germination (51%), seedling (34%), root length (48%) and seedling dry weight (41%) of A. lebbeck occurred at 7 mM mercury treatment. A. lebbeck showed high percentage of tolerance (78.14%) to mercury at 1 mM. However, 7 mM concentration of mercury produced lowest percentage of tolerance (51.65%) in A. lebbeck. The seed germination potential and seedling vigor index (SVI) clearly decreased with the higher level of mercury. Plantation of A. lebbeck in mercury-polluted area will help in reducing the burden of mercury pollution. A. lebbeck can serve better in coordinating in land management programs in metal contaminated areas. The identification of the toxic concentration of metals and tolerance indices of A. lebbeck would also be helpful for the establishment of air quality standard.

Wheat is one of the most important grains. Its consumption is increasing globally. Many countries are making efforts to increase the extent of wheat harvest. It is known that plant growth promoting rhizobacteria (PGPRs) have beneficial effects on various plants. Two PGPRs including Paenibacillus pabuli strain P7S (PP7S) and Pseudomonas nitroreducens strain IHB (PnIHB) were employed to investigate effects of PGPRs on early growth of three wheat cultivars (Koso, Seakumkang, and Jokyung). While PP7S had adverse effects on Seakumkang and Jokyung, PP7S had positive effects on Koso except root length compared to control group having no treatment of PP7S. However, all treatments with PnIHB had adverse effects on germination rate, root/shoot lengths, vigor index, and dry root/shoot weights of all three wheat cultivars. These positive effects with PP7S on Koso might be related to the earlier emergence of wheat seed above soil which is known to be an indicator of increased yield. Results of the present study suggest that if proper PGPR strains are selected, they could have positive effects on early growth rate of a wheat cultivar.

Background and objective: With increasing land use intensity in urban areas, apartment buildings have been recognized as a typical type of urban residence. In this study, the impacts of different views through a window on health-related responses were investigated using psychological and physiological parameters. Methods: Photos of three different types of views taken on low (2-12 m), middle (28-35 m), and high (over 54 m) floors of dense apartment building areas were used as visual stimuli. Twenty-two healthy adults participated in the indoor experiment. Semantic differential methods and profile of mood states were used as psychological tools. Autonomic nervous activity was evaluated using blood pressures, pulse rate and heart rate variability (HRV). Results: Analytic data showed different characteristics of psychological and physiological outcomes in three different apartment views. In the analysis of psychological parameters, significantly negative responses to the views on middle floors were found in the subscales of tension-anxiety and anger-hostility, compared to low floors. Significantly positive scores in the subscale of vigor were found on low floors with abundance of vegetation and high floors with a view of the sky. A significantly increased value of HF was found on low floors (2,294.96 ± 169.79), compared to the middle(1,553.45 ± 84.66) and high (1,523.02 ± 70.49) floors. Despite the high scores in openness and vigor, high floor views showed significantly higher LF/HF values (1.83 ± 0.09), the indicator of the sympathetic nervous system, than low (1.30 ± 0.07) and middle floor views (1.34 ± 0.06), which might be related to the unconscious fear of heights. Conclusion: Views from different heights in an apartment building can affect the psychological states of residents. Green space through the window may have a positive health outcome by reducing physiological stress.
