Interest in spirituality in the workplace is rising as an alternative to overcome the possibility of burnout of social workers. This research has evaluated the results of spirituality education program to social workers in senior welfare centers. CPE(Clinical Pastoral Education) was provided to 25 social workers in 3 different senior welfare centers for 12 to 14 weeks. 4 Focus group interviews with 24 education participants after the end of education were conducted. For the participants of CPE, there were changes in individual levels(habituation of self-reflectivity, the integration of personal spirituality and social worker's spiritualty, expansion of self-awareness and pursuit of altruism), practice behavior(recognition of client's individualism, getting rid of the obsession of proposing a resolution, active listening), and organization levels(intimate fellowship, increase in horizontal relationship in the agencies). Pursuing changes within the organization towards integrating individual and organization spirituality along with social welfare organizations helping the development of social worker's individual spirituality for the simultaneous growth of social workers and the organizations is necessary.

This study investigates the effects of Psidium guajava L. leaf (Pg), Lagerstroemia speciosa L. leaf (Ls) and mixture A (Pg, Ls, Morus indica L. leaf extract, Pinus densiflora needles extract, Acanthopanax senticosus M. root extract) on streptozotocin (STZ)-diabetes rats. For four weeks, STZ-diabetes rats were fed crystallized extracts of Pg, Ls, and mixture A. Compared to the diabetic control group, extracts of Pg, Ls, and mixture A decreased glucose levels in rats by 20%, 14% and 24% respectively. These extracts also decreased the level of total cholesterol, triglyceride and free fatty acid, compared to the diabetic control group, while effectively increasing levels of insulin and high-density lipoprotein-cholesterol. These results showed that mixture A had greater antihyperglycemic, antihyperlipidemic, and insulin-increasing effects than the Pg and Ls extracts. Mixture A also showed better restoration of damaged beta cell function compared to Pg and Ls extracts. Therefore, it was proved that mixture A provides a beneficial synergistic effect when compared with Pg and Ls extracts used individually.

This study was conducted to estimate the contents of trace metals in vegetable which were produced in Korea. The levels of trace metals determined using a mercury analyzer, and ICP (inductively coupled plasma spectrometer) and an AAS (atomic absorption spectrophotometer) after wet digestion. The values of trace metals [minimum~maximum (mean), mg/kg] in vegetables were a follows ; Hg : 0.0001~0.019 (0.002), Pb : 0.001~0.28 (0.02), Cd : 0.001~0.078 (0.016), As : 0.001~0.06 (0.02), Cu : 0.06~24.81 (0.77), Mn : 0.17~15.12 (2.32), Zn : 0.13~28.70 (2.51). These results showed that metal contents in vegetables on domestic markets were similar to those reported in other countries. The weekly average intakes of lead, cadmium and mercury from vegetables take 2~7% of PTWI (Provisional Tolerable Weekly Intakes) that the FAO/WHO Joint Food Additive and Contaminants Committee had set to evaluate their safeties.

Purpose: To examine the effects of a 36-week resistance training program on body composition, fitness and blood lipid profiles in the obese elderly. Method: fourteen subjects were assigned into the resistance training group. The 12-16 exercise sessions were performed for 60min with 15-25 repetitions twice per week for 36 weeks. Data were analyzed by paired t-test with SPSS version 12.0 for Windows. Results: Significant changes were evident in weight (t=5.983, p<.001), body mass index (t=5.922, p<.001), % body fat (t=3.480, p=.004), and fat free mass (t=-2.592, p=.022). Concerning exercises, no significance was noted for back scratch (t=-1.814, p=.093), but were for 2-min step (t=-3.075, p=.009), arm curl (t=-2.223, p=.045), chair stand (t=-3.671, p=.003), chair sit and reach (t=-2.508, p=.026), and 8-ft up and go (t=5.545, p<.001). No significant changes were evident in total cholesterol (t=1.189, p=.279), and total glucose (t=0.689, p=.517), while the change in high-density lipoprotein was significant (t=3.535, p=.012). Conclusion: The 36-week resistance training program enhanced body composition and physical fitness, but not blood lipid profiles in obese elderly subjects.

Vessel traffic servies (VTS) control movements in ports and coastal areas 24 hours a day using VHF. Thus, we were able to check ship movements and the patterns followed by VTS officers in VTS areas using VHF communication analysis. This study is intended to identify control intervals for dangerous situations and provide VTS officers with basic data and guidelines to prevent these occurrences in advance. We listened to Busan port's VHF communication for seven days and obtained risk values using the Park model with reference to controlled ships. The probability of a dangerous situation arising under a controller's watch per unit of time was confirmed to follow a Poisson distribution. As a result, for each 3.50 hours that VTS directly controls an area, (and in daytime for each 2.85 hours) a ship communicates in a VTS area every 3.84 hours, and some of there communications exceed certain risk values in VTS areas.

Mature nodal segments of 2-year-old greenhouse stock plant were cultured on Murashige and Skoog basal medium supplemented with the different kinds and various concentrations of cytokinins to produce multiple shoots in in vitro condition. The most adventitious shoots were produced from excised ends of nodal segments. The highest average number $(24.6\;{\pm}\;4.6)$ of shoots was produced with the combination of BA 1.0mg/L and TDZ 0.1mg/L in MS medium. In addition, several shoots were formed from lenticels of bark cambium with the same treatment. These concentrations promoted high shooting capability upto $94.6\%$ and NAA was the best cytokinin among five different PGR sources.
