In order to produce Laminaria japonica in Jeju as feed for abalone, a transplant experiment was performed with the Baekryungdo and the Wando cultivar stocks at the Udo aquafarm from January to July 2003. Eight water conditions at the aquafarm and eleven traits of the two cultivar stocks were measured once a month. The water temperature ranged from 12.9$^{\circ}C$ to 23.5$^{\circ}C$. The salinity was 31.3-36.8‰ the DO was 5.40-9.86 mg ${\cdot}$ $l^{-1}$ the pH was 7.82-9.61. Concentrations of $NO_2-N,\;NO_3-N,\;NH_4-N\;and\;PO_4-P$ were 0.02-0.15 $\mu$M, 2.27-3.49 $\mu$M, 0.16-0.56 $\mu$M and 0.07-0.99 $\mu$M, respectively. The whole frond length of the Baekryungdo and the Wando specimens were 173.84 and 153.67 cm. The blade width, stipe length, blade length, fascia length, blade thickness, total weight and substantiality of the Baekryungdo and the Wando specimens were 14.61 and 13.05 cm, 3.94 and 3.02 cm, 169.88 and 150.65 cm, 155.81 and 137.10 cm, 1.01 and 0.96 cm, 258.04 and 200.96 cm, and 101.56 and 94.62, respectively at the conclusion of the experiment in July. The measurements of the Baekryungdo specimens were slightly higher than those of Wando specimens. The fascia width, stipe thickness and fascia thickness of the Wando specimens were slightly higher than those of the Baekryungdo specimens. The relative growth rates of these traits of two cultivar stocks during the growth test were very similar. Generally, the performance of the Baekryungdo cultivar stock seems to be better than that of the Wando samples. Further study of the physiological ecology for cultivation and breeding is needed in the future.

Purpose: The purpose of this study was to examine the under-reporting rate and related factors after blood and body fluid (BBF) exposure among hospital employees. Methods: Fifteen hundred l employees were conveniently sampled from ten university and acute care hospitals. The survey questionnaire consisted of 37 items. Data were collected from September 10 to November 30, 2008. Results: The survey response rate was 88.7%. The 47.9% (638/1,331) of hospital employees were exposed to BBF and the mean number of exposure was $4.7{\pm}5.942$ within the previous year. Under-reporting rate after BBF exposure was 69.4% (443/638). By multi-variate logistic regression analysis, the exposure number, exposure type, infectious disease and hospital were independently related to the under-reporting of BBF among hospital employees. Conclusion: The under-reporting rate after being exposed to blood and body fluids was relatively high. To address this problem, educational programs are needed to decrease the under-reporting rate for healthcare workers. Further, it might be helpful if other factors related to under-reporting be investigated in future studies.

In recent decades, decreasing trends in esophageal cancer mortality have been observed across China. We here describe esophageal cancer mortality trends in Linzhou city, a high-incidence region of esophageal cancer in China, during 1988-2010 and make a esophageal cancer mortality projection in the period 2011-2020 using a Bayesian approach. Age standardized mortality rates were estimated by direct standardization to the World population structure in 1985. A Bayesian age-period-cohort (BAPC) analysis was carried out in order to investigate the effect of the age, period and birth cohort on esophageal cancer mortality in Linzhou during 1988-2010 and to estimate future trends for the period 2011-2020. Age-adjusted rates for men and women decreased from 1988 to 2005 and changed little thereafter. Risk increased from 30 years of age until the very elderly. Period effects showed little variation in risk throughout 1988-2010. In contrast, a cohort effect showed risk decreased greatly in later cohorts. Forecasting, based on BAPC modeling, resulted in a increasing burden of mortality and a decreasing age standardized mortality rate of esophageal cancer in Linzhou city. The decrease of esophageal cancer mortality risk since the 1930 cohort could be attributable to the improvements of socialeconomic environment and lifestyle. The standardized mortality rates of esophageal cancer should decrease continually. The effect of aging on the population could explain the increase in esophageal mortality projected for 2020.

The purpose of this study is to calculate the energy consumption rate based on data regarding energy use in office buildings, and to confirm the general characteristics of energy consumption. The energy consumption rate of the building is calculated by dividing the energy consumption by the floor area. The energy consumption rate of small-sized office buildings was calculated as $101.48{\sim}201.55kWh/m^2{\cdot}year$ and in the case of medium-sized buildings, the range was $92.77{\sim}177.89kWh/m^2{\cdot}year$. In the case of small buildings, it was found that the energy consumption was $73.24kWh/m^2{\cdot}year$ in electronic device, $34.31kWh/m^2{\cdot}year$ in hot water supply, and $18.37kWh/m^2{\cdot}year$ in heating. In the case of medium-sized buildings, electronic devices was $73.08kWh/m^2{\cdot}year$, lighting was $18.35kWh/m^2{\cdot}year$ and heating, $15.37kWh/m^2{\cdot}year$. In all of the study buildings, the peak heating energy use was observed from 8:00 a.m. to 10:00 a.m during the winter, and the peak power management was required. Energy use at and around the midnight hour is confirmed to be 40~60% of weekly working hours, so it is necessary to manage power use at night time as well as during the day. In order to improve the accuracy of future studies, it is necessary to make efforts to secure the data with standardized energy measuring units for the various type of buildings.

Objectives: Stress hormone (cortisol) can be used to analyze psychological and physiological changes and healing effects before and after in blood and saliva. Here it is applied to scientifically validate the effects of the healthy forest experience in Deogyusan Mountain National Park. Methods: A healthy forest experience program was provided to college students (males and females) at Deogyusan National Park. Stress, hormones (cortisol), blood pressure, pulse, oxygen saturation and stress, anxiety, and depression were measured. This study was designed to objectively analyze the effects of stress hormones before and after. Results: Depression, stress, anxiety, and satisfaction with the forest experience program in Deogyusan National Park were very high in reliability in terms of Cronbach's Alpha: depression scored 0.910, stress 0.558, anxiety 0.934, program satisfaction 0.826, and program effectiveness 0.894. Conclusions: In this study, we utilized the Healthy Forest Experience Program and the 'Health and Medical Center Health Record Book' of the Health Forest Experience Program (Ministry of Environment's Environmental Education Certification Program). In the future, we will seek ways to utilize saliva since it is easier to collect than blood samples and apply the stress hormone cortisol as a saliva authentication program. In addition, by implementing ecological welfare programs in which nature and human beings coexist through systematic preservation and restoration, the national park management can utilize ecological, scenic and cultural services wisely. We expect to be able to provide exploration and welfare services.
