This work Was carried out to obtain the most suitable crop coefficient for the paddy rice growing in Taegu area. The result was due to the comparative measurements of evapotranspiration formula in terms of Blaney & Criddle and eight other formulas with those produced by experiment particularly in this area. The crop coefficient, evapotranspiration and transpiration ratio produced by this research are hopefully expected to be of service in the future calculation of evapotranspiration without repeating experiment respectively, whenever the water requirement of paddy rice is planned in Taegu and its vicinity. The accomplished results could be summarized as follows : The maximum amount of evapotranspiration was recorded in the early and middle parts of August. The average reading of evapotranspiration was 6.33mm/day throughout the growth. The evapotranspiration had a highly significant correlation with pan evaporation, solar radiation, sunshine hours and relative humidity of meteorological elements. K and Kc by the use of Blaney & Criddle formula calculated at 0.76 to 1.45 and 0.82 to 1.27, respectively. Its peak value appeared commonly in early August. The ratio of transpiration was 269.03.

The purpose of this study is to illuminate historical sensitivity and design in the days of the Joseon era and examines the phenomenon of acculturation as revealed in the planting of Sophora japonica and Zelkova serrata in the garden grove by looking into the purpose underlying the construction, formative intention and the process of change in Pohang's Chirinjeong wonlim. Chirinjeong, also called Sanggaejeong(雙槐亭) after the fact that two Zelkova serrata trees were planted there, is a hermit pavilion in Sa-il village, Chogok-ri, built in the 9th year of King Taejong(1409) by Jang, Pyo(張彪, 1349~?) of an officer of bureaucratic origin toward the end of the Goryeo Dynasty, the Chirinjeong garden grove is an element essential to Chogok, the 3rd Gok of Sanggaegoogok(雙溪九曲). The wonlim of Chirinjeong is divided into the pavilion section composed of the entrance area, Chirinjeong, composed of Zelkova serrata and Sophora japonica, and the pond section composed of a quadrangular pond and island(方池方島), and Lagerstroemia indica. In view of the intent of the name Chirinjeong or of the fact that the pavilion was named based on that the royal seal string was hung on the Sanggwaesoo(雙槐樹) or two Zelkova serrata trees, it is reasonable to view it as Zelkova serrata trees having been planted early in the days of the Joseon Dynasty and those additionally planted later on that symbolizes the position of the three nobles and the Sophora japonica. In addition, in spite of the fact that the type of trees supplementarily planted in the 21st year of King Yeongjo(1745) is known as Sophora japonica, it is impossible to rule out the possibility of the tree planted outside of Chirinjeong being Zelkova serrata. In short, the three Zelkova serrata trees planted along with Sophora japonica must certainly be evidence that Zelkova serrata planted along with Sophora japonica in Chirinjeong wonlim indicates that the off spring of the Indong Jang family could tell the difference between Sophora japonica and Zelkova serrata. In the recognition process of Zelkova serrata trees finding their way into Korea, it was known as Zelkova serrata on the one hand and as Sophora japonica on the other, and the former, which enjoys a comparative advantage over in terms of the easiness with which to purchase, growth speed and possibility of growing into a long-lived tree was interchanged with Zelkova serrata, a case of acculturation as manifested in the planting of Sophora japonica in the Chirinjeong garden grove.

This study examined the institutional improvement directions of industrial security programs, particularly focusing upon policies and practices in the U.S., to enhance the effectiveness of industrial security programs in Korea. This study also aimed to investigate the significance of institutional and/or policy implementations in preventing economic espionage attempt. Data leakage and/or loss of trade secrets in corporations has been a scary proposition and a serious headache to both the CEOs and the CSOs(Chief Security Officers). Security professionals or practitioners have always had to deal with data leakage issues that arise from e-mail, instant messaging(IM), and other Internet communication channels. In addition, with the proliferation of wireless and mobile technology, it's now much easier than ever for loss by data breaches to occur, whether accidentally or maliciously or even by an economic espionage attempt. The researcher in this study used both a case study and a comparative research to analyze the different strategies and approaches between the U.S. and Korea in regard of implementing policies to mitigate damages by economic espionage attempts and prevent them from occurring. The researcher first examined the current policies and practices in the U.S. in terms of federal government's and agencies' approach and strategies on industrial security programs and their partnerships with private-commercial-sectors. The purpose of this paper is to explain and suggest selected findings, and a discussion of actions to be taken on implementing a proactive and tactical approach to enhance the effectiveness of industrial security programs to fight against information loss or data leaks. This study used case reviews, literatures, newspapers, articles, and Internet resources relating to the subject of this study for triangulation of data. The findings during this research are as follows. This research suggests that both the private and the governmental sector should closely cooperate in the filed of industrial security to strengthen its traditional prevention strategies and reduce opportunities of economic espionage as well. This study finally recognizes both the very importance of institutional development led by the Government in preventing economic espionage attempts and its effectiveness when properly united with effective industrial security programs.

The present study examined the comparative effects of various amino acids on the alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) activities of yeast Saccharomyces cereviciae and rat liver homogenate in vitro. Methionine showed the highest activity in yeast ADH among the amino acids used in this study, but this was not higher than that of the hangover product, Condition-Power (CP) used as positive control. Methionine was also found to be the best amino acid in terms of the ALDH activity in rat liver homogenate among the treatment amino acids, which was comparatively higher than that of positive control CP. It was chosen for further experiments and yeast ADH activity increased in parallel with increased methionine concentration, but not rat liver ALDH activity, and it was comparatively higher than those of the positive control. Arginine showed the highest values in yeast ALDH and rat liver ADH activities among amino acids, and it was chosen for further experiments. Yeast ALDH activity increased in parallel with increased arginine concentration, which was higher than that of positive control CP, and rat liver ADH activity was also comparatively higher in all treatment concentrations of arginine than that of positive control CP. The native electrophoresis of ADH and ALDH from cell-free extracts of yeast Saccharomyces cerevisiae cultured in the growth medium containing various arginine concentrations by $0{\sim}0.1%$ showed two active bands upon zymogram staining analysis, and the straining intensity of ADH and ALDH active bands in arginine treatment yeast was stronger than that of non-yeast or low treatment yeast. These results indicate that alcohol metabolizing enzyme activities can be enhanced by arginine and methionine, suggesting that arginine and methionine have potent ethanol-metabolizing activities.

Endotracheal suctioning is a routine procedure used for clearing secretions from the airway of the intubated infant. This procedure is not without complications. Endotracheal suctioning has been associated with decreases in $PaO_2$, decreases in systemic venous oxygenation, alterations in mean arterial Pressure, disturbances in cardiac rhythm and development of nosocomial pneumonia. So several endotracheal suctioning techniques have been developed to prevent these blown complications. Another method of Endotracheal suctioning eliminates the risk associated with disconnecting the infant from the ventilatior to perform the suctioning procedure. Studies examining closed endotracheal suctioning methods reported that the closed method results in less arterial oxygen saturation, and less systemic venous oxygen desaturation. However those studies have focused on adult patients, and there have been no published studies for newborn infants. The specific purpose of this study is to investigate the two methods and to make a comparison in terms of (1)variations in $SaO_2$, heart rate, and respiration rate appeared before and after the endotracheal suctioning; (2)difference in occurrence of nosocomial infection; (3)difference in recovery time to arrive at pre-suction baseline after suctioning and in nursing time taken for the suctioning. The present study is based on the data obtained from two groups of newborn infants : one group comprises 8 infants with closed suctioning (a total of 304 suctions) among 17 infants treated with ventilator and the other group 9 infants with open method (a total of 629 suctions). The data were analyzed using the SPSS statistical program package. As the distribution test on dependent variables with the Skewnesser Shapiro Wilk test showed an asymmetric distribution, the Wilcoxon Matched-pairs Singled- Ranks test was used for the test of variations in $SaO_2$, heart rate, and respiration rate appeared before and after the endotracheal suctioning. The difference in $SaO_2$ recovery time and nursing time was analyzed with the Mann-Whitney U-Test. The difference in physiologic consequences and occurrence of nosocomial infection between the two groups was analyzed with the Fisher's Exact Test. The results of the study are summarized as follows. For the hypothesis 1 (There would be a difference in $SaO_2$, heart rate, and respiration rate before and after suctioning between the two suctioning methods), the difference in $SaO_2$ turns out to be statistically significant (P=0.015), but heart rate and respiration rate do not procedure a notable difference (P=0.630). The hypothesis 2 (There would be a difference in rates at which a complication arises after suctioning between the two groups) does not prove to be statistically valid (P=0.246). For the hypothesis 3(There would be a difference in $SaO_2$ recovery time and nursing time between the two groups), the average $SaO_2$ recovery time after suctioning turned out to have somewhat significant difference (P=0.064), however the difference in nursing time taken for the suctioning was not statistically significant (P=0.610). The analyses indicate that the closed endotracheal suctioning is more efficient as compared with the open method, in maintaining pre-suction baseline $SaO_2$ and a rapid recovery of newborn infants. Based on these results we suggust to apply the closed method to newborn infants in the ventilation treatment. We also suggest to extend the investigation to include the comparison of suction cost taking into account the case in which a complication arises after endotracheal suctioning between the two groups.

We investigated foodservices and levels of their satisfaction from parents of children in kindergartens with and without dietitians. Foodservice facilities consisted of kitchens and cafeterias for all kindergartens with a dietitian (KWD) and only kitchens for all kindergartens without a dietitian (KWOD) (p<0.001). Children consumed lunch in a lunchroom for all KWD and in a classroom for all KWOD (p<0.001). The person in charge of the diet menu was a dietitian for all KWD and a director for 52.2% of KWOD (p<0.001). About 48% of total kindergartens were served different amounts according to the child's age and body size. About 30% of parents from total kindergartens responded that a difficulty of foodservice management was children's safety while distributing the lunch. The majority of respondents claimed that foodservices need a more balanced menu and active instructions on proper dietary habits. Parents who visited and participated in foodservice were significantly higher from KWD than KWOD. Also, the desire to participate in foodservices was significantly higher in the parents from KWD (p<0.01). Sixty one percent of parents from KWD and 19% of parents from KWOD considered foodservices when choosing a kindergarten (p<0.001). The satisfaction in foodservices of parents from KWD was significantly higher from all points of view in terms of the quality of foodservice, nutrition, and hygiene. In conclusion, we found that foodservices and their levels of satisfaction from parents of kindergartens with dietitians were better and higher than those without dietitians. Therefore, all kindergartens should consider having a dietitian exclusively in charge of foodservices.

The aim of this study is to be able to understand the problems within the urban agriculture policy promoted by the Government and local autonomous entity base on the comparison of the consciousness of the urban agriculture between urban farmers and public officials and to inquire into the further revitalization scheme in the end. For this purpose, this study drew implications through studying latest trend and the legislation of domestic and foreign urban agriculture and then conducted a questionnaire survey of urban farmers and public officials. Because of this research, the revitalization schemes of urban agriculture are as follows: First, it's necessary to secure the usable arable land, such as the green roof, community garden, as well as urban agriculture park, etc. Second, it is necessary to establish the urban agriculture relations act suited for the actual circumstances of our country and to back up the legislation at an institutional, technological level in terms of a nation in order to secure the durability of urban agriculture. Third, it is advisable to make a proposal about the problems in time of activities for cultivation by forming a network between urban farmers and public officials and to prepare the plan for the active exchange of farming technologies. Fourth, it's necessary to activate the community gardens by supplying the education through cultivation method & its management method, and a variety of urban-agriculture-participation programs. Fifth, it is necessary to set up the specialized and practical education through an institute for landscape architecture. Sixth, it is necessary to induce the spontaneous participation in urban agriculture from urban farmers accompanied by the activities for promotion that are worth arousing urban farmers' interest. Lastly, it is also necessary to establish a legal basis of urban agricultural parks and facilities as well as to promote a search for multilateral policies and their practice so that the further urban agriculture can be stably continued within city boundaries.

These days, environmental policies have changed from being command and control systems toward economic incentive systems, with various incentives having been established by OECD countries. In Korea, many environmental charges have been established in order to diminish activities which damage natural resources. Among them, the Ecosystem Conservation Cooperation Charge and the Replacement Charge for Forest Resources Creation are considered to be representative environmental charges. These charges, along with a few others, were designed to encourage efforts to protect natural resources. The charges include a number of different features, utilize varying methods, and altered ranges of jurisdiction. However, the charges may pose serious inequity problems in terms of their estimated values and their conditions of reduction and exemption. For instance, although the Ecosystem Conservation Cooperation Charge is a primary charge applied to natural resource damage, the charge does not fully secure its original objectives due to its low levy and limited range of provisions. Moreover, the Replacement Charge for Forest Resources Creation has been criticized because of similar reduction and exemption provisions. Therefore, this study analyzes the inequity problems associated with the charges and proposes solutions. First of all, the Ecosystem Conservation Cooperation Charge should be redesigned in such a way that it reflects the substantial value of natural resource damage through either abrogate or increased maximum limits of the charge. With regard to the Replacement Charge for Forest Resources Creation, the cases and ranges of reduction and exemption provisions should be narrowed. Finally, the charges collected should be expended in conformity with their original objectives, and their expenditure should be restricted to either restoration activities or activities directly related to compensation and mitigation of damaged natural resources.

The comparative experiments were conducted for single span greenhouses where cucumbers were cultivated to analyze the effect of heating between a carbon fiber electric heating element heater and an oil hot air heater in terms of the inside climate, energy consumption and plant growth. In order to analyze the effect of heating capacity, 6, 9, and 16 kW of electric powers were supplied to the electric heating element for same setting temperature of 15?. As a result, as the heating capacity increased, the number of ON-OFF cycles of the electric heating element and the temperature inside the greenhouse increased proportionally. In the comparison of two heaters, it was shown that the temperature and relative humidity distributions of the electric heating element installed greenhouse was much uniform than those of the oil hot air heater installed greenhouse. The heating energy consumptions during the heating period of 79 days were 867L for the oil hot air heater and 8,959 kWh for the electric heating element heater, and the heating costs were 607 and 403 thousand won respectively. In the electric heating element installed greenhouse, the cucumber growth was slightly better and the yield was 4.3% higher than those of the oil hot air heater installed greenhouse, but there were no statically significant difference in the cucumber growth and yield between greenhouses.

Purpose: To evaluate two different heel lancet device in terms of pain response and success of the procedure in the preterm infants undergoing heel puncture. Methods: 100 preterm infants undergoing capillary blood gas analysis or capillary bilirubin monitoring underwent heel puncture, were randomly allocated to blood sampling from the heel with either a conventional manual lancet or an automatic incision device. Primary outcome measures included the Premature Infants Pain Profile (PIPP) score, total duration of procedure, number of heel puncture and number of bruise. The pain response was evaluated using PIPP score and the effectiveness was evaluated using three criteria: total duration of blood sampling, number of puncture, bruising of the heel or ankle. Statistical analysis was performed using the SPSS ver. 13.0 program. Difference between the groups were analysed with t test (continuous variables) and the Chi square test or Fisher test (categorical variables). Results: The mean PIPP score was 4.91 for the automatic lancet group compared with 5.84 for the conventional manual lancet group (P=0.0255).The number of pain scores above 7 during blood collection did not differ between two groups (P=0.2167). The procedure took less time to perform in the automatic lancet group (mean, 30.69 seconds) than in the conventional lancet group (mean, 48.92 seconds) (P<0.0001). Conclusion: This study demonstrated that the automatic lancet device causes less pain and a shorter procedure time than the conventional manual lancet in preterm infants undergoing heel puncture. On the basis of these results the automatic lancet device is very useful method for blood collection in preterm infants by heel puncture.
