Greenhouse gas(GHG) inventories were reported recently in various fields. It, however, has been rarely to mention about the accuracy and reliability of the GHG inventory results. Some reliable assessment methods were introduced to judge the accuracy of the GHG inventory results. It is, hence, critical to develop an evaluation methodology. This project was designed 1) to develop evaluation methodology for reliability of inventory results by GHG-CAPSS, 2) to check the feasibility of the developed evaluation methodology as a result of applying this methodology to two emission sources: liquid fossil fuel and landfill, and 3) to construct the technical roadmap for future role of GHG-CAPSS. Qualitative and quantitative assessment methodologies were developed to check the reliability and accuracy of the inventory results. Qualitative assessment methodology was designed to evaluate the accuracy and reliability of estimation methods of GHG emissions from emission and sink sources, activity data, emission factor, and quality management schemes of inventory results. On the other hand, quantitative assessment methodology was based on the uncertainty assessment of emission results. According to the results of applying the above evaluation methodologies to two emission sources, those seem to be working properly. However, it is necessary to develop source-specific rating systems because emission and sink sources exhibit source-specific characteristics of GHG emissions and sinks.

The purpose of this study was to examine the effects of hand massage as a nursing intervention on the anxiety of the hysterectomy patients in immediately prior to surgery. The method of this study was Nonequivalent Control Group Non-Synchronized Design. The data were selected from at K university hospital in Pusan, and they consisted of Experimental group-25 patients, Control group -24 patients. The data were collected from Jan. 4 to Jan. 30 in 1999. The subjects′ self-reports of anxiety (measured by the Spielberger Trait-State anxiety Inventory and Visual Analogue Scale developed by Cline et al.) were recorded before and immediately after the intervention. The objective physiologic measures of blood pressure and pulse rate. The collected data were analysed by means of frequency, percentage, standard deviation, chi- square test, t-test, ANCOVA with SPSS program. The results of this study were as following; 1. Hypothesis 1: The 1st hypothesis that "There will be significant difference of the state anxiety level just before surgery in the experimental group and control group" was supported(P= .000). 2. Hypothesis 2: The 2nd hypothesis that "There will be significant difference of the visual analogue scale score just before surgery in the experimental group and control group"was supported(P= .000). 3. Hypothesis 3: The 3rd hypothesis that "There will be significant difference of the systolic and diastolic blood pressure level just before surgery in the experimental group and control group"was supported (P= .003, P= .041). 4. Hypothesis 4: The 4th hypothesis that "There will be significant difference of the pulse rate just before surgery in the experimental group and control group"was supported(P= .004). In conclusion, hand massage is a benefical nursing intervention that alleviates the psychological, physiological anxiety of the hysterectomy patients in immediately prior to surgery. therefore it is recomended to use the hand massage as a nursing intervention for patients undergoing anxiety. The results of this study appear promising, additional research is recomended to further the appropriate uses of hand massage in nursing practice for this and other patient population.

Purpose: This study examined the effects of training using the slime on the hand function and problem behavior in adults with intellectual disabilities. Methods: Five adults with intellectual disabilities who were judged as Level 1 or Level 2 were selected. The training consisted of one session (50 min)/day, one day/week for 10 weeks (preparatory activities: 5 min, slime activities: 40 min, finishing activities: 5 min) The functions of the hand (Purdue Pegboard Test [PPT], grip strength test [GST]) and problem behavior (Korean Behavior Problems Inventory [KBPI]) were assessed three times (first assessment; pre, second assessment; post-5 weeks, third assessment; post-10 weeks). Wilcoxon signed-rank tests were used to analyze changes in the subjects' performance before and after the intervention. Results: In the PPT, the use of the non-dominant hand was increased significantly (p<0.05). No significant differences were observed in the remaining results, but the mean value increased. In addition, although the problem behavior was not statistically significant, an increase in the problem behavior score was noted. Conclusion: The training using the slime for adults with intellectual disabilities is effective in hand function improvement and reducing problem behavior.

In this study, land-use changes from 1990 to 2010 in Jeju Island by different approaches were produced and compared to suggest a more efficient approach. In a sample-based method, land-use changes were analyzed with different sampling intensities of 2 km and 4 km grids, which were distributed by the fifth National Forest Inventory (NFI5), and their uncertainty was assessed. When comparing the uncertainty for different sampling intensities, the one with the grid of 2 km provided more precise information; ranged from 6.6 to 31.3% of the relative standard error for remaining land-use categories for 20 years. On the other hand, land-cover maps by a wall-to-wall approach were produced by using time-series Landsat imageries. Forest land increased from 34,194 ha to 44,154 ha for 20 years, where about 69% of total forest land were remained as forest land and 19% and 8% within forest lands were converted to grassland and cropland, respectively. In the case of grassland, only about 40% of which were remained as grassland and most of the area were converted to forest land and cropland. When comparing land-cover area by land-use categories with land-use statistics, forest areas were underestimated while areas of cropland and grassland were overestimated. In order to analyze land use change, it is necessary to establish a clear and consistent definition on the six land use classification.

In preparing a aggregate production plan(APP), the transportation method generally uses a linear planning(LP) software package for TSM(transportation simplex method), which seeks initial solutions with either NCM, LCM, or VAM specialized in transportation issues and optimizes them with either SSM or MODI. On the other hand, this paper proposes a transportation method that easily, quickly, and accurately prepares a APP without software package assistance. This algorithm proposed simply assigned to least cost-first, and minimized the inventory periods. Applying the proposed algorithm to 6-benchmarking data, this algorithm can be obtained better optimal solution than VAM or LP for 4 data, and we obtain the same results for the remained 2 data.

The main purpose of this study was to identify the effect of hand massage on pain and anxiety related to chest tube removal in patients with a lobectomy. The research design of this study was a nonequivalent control group non-synchronized design. Of the twenty nine adult subjects, fourteen were assigned to the experimental group and fifteen to the control group. The data were obtained over 3 months from a medical center in Seoul. The instruments used to assess trait state anxiety was the Spielberger Trait-State anxiety Inventory. For pain and psychological anxiety. The Visual Analogue Scale was used. Hiko analogue sphygmo-manometer(2001) was used to check blood pressure and pulse rate as indicators of physiological anxiety Subjects in the experimental group received hand massage for 5 minutes just before chest tube was removed, and subjects assigned to the control group did not receive hand massage. Data were analysed with $x^2$-test and Mann-Whitney U test using the SPSSWIN 10.0 program. The results of the study are as follows : 1. Hypothesis 1: 'there will be a significant difference between two groups in the level of pain after chest tube removal' was supported (u = 23.00, p < 0.001). 2. Hypothesis 2: 'there will be a significant difference between the two groups in the level of psychological anxiety after chest tube removal' was supported (u = 3.00, p < 0.001). 3. Hypothesis 3: 'there will be a significant difference between the two groups in physiological anxiety(systolic, diastolic blood pressure and pulse rate) after chest tube removal' was supported(u =55.50, p = 0.01 ; u = 41.50, p = 0.01 ; u = 20.50, p < 0.001, relatively). The findings of this study indicate that hand massage is effective for pain and anxiety related to chest tube removal in patients with lobectomy. Therefore, hand massage is recommended as an effective nursing intervention for relieving pain and anxiety in patients undergoing chest tube removal. Further research is needed to identify the proper duration and timing to achieve the optimal effect of hand massage. A larger subject population is required to apply the current findings to the general population. Further research is also needed to assess the effects of hand massage in other patient subsets. Finally, it would be interesting to see if the effects of hand massaging would be attenuated when performed by a non-medical specialist.

Objectives: This study was conducted to investigate the emotional characteristics of the patients within one year after stroke using the Core Seven Emotions Inventory-Short Form. Methods: It analyzed the medical records of 39 stroke patients who had visited W University hospital and completed the Core Seven-Emotions Inventory-Short Form (CSEI-S), the K-MBI, the PWI-SF, and the HADS. Patients data were analyzed by descriptive analysis, frequency analysis, the Mann-Whitney U test, and the nonparametric test of the CSEI according to the period of stroke onset in patients and Spearman's correlation analysis using the SPSS (Statistical Package for the Social Science, IBM, United States of America) Version 23.0. Results: First, in the case of depression, all subjects were in the danger group, although more than half of the joy, anger, thinking, sadness and fear were included in the normal group in the shortening of the key seven-point scale. Secondly, in measuring the social and psychological stress and hospital anxiety and depression, social and psychological stress were indicated to be a potential danger group, while anxiety and depression were shown to be a healthy group. Thirdly, the emotional characteristics were explored according to the sub-factor of the shortening of the key seven-figure emotional scale after being classified within two months, between two and six months and over six months depending on the duration of the outbreak. As a result, statistically significant, Joy was the highest score over six months and the lowest score between two and six months. On the other hand, the case of depression was depicted to be significantly lower at over six months, and was highest between two and six months. Finally, the correlations on each scale were statistically significant. Conclusions: This study provided that the CSEI-S can be used to simply to measure the emotions of patients according to the period of the onset of stroke in the clinical scene.

This study reconstructed the military logistics improvement project currently being implemented by ROK military as a defense logistics strategy. In addition the factors affecting the performance of the defense logistics strategy are analyzed using PLS. The significance of this study is as follows. First, the defense logistics improvement project was structured as a defense logistics strategy according to function. Second, PLS is used for performance factor analysis. Most of the existing defense researches utilized the ML structural equation. However, this study used the PLS structural equation in view of the fact that each detail project is the formation of defense logistics strategy. Third, we identified projects that have a substantial impact on defense logistics performance and those that do not. We found that inventory, process, and information strategy influenced logistics performance among defense logistics strategies. On the other hand, it was confirmed that the facility/equipment strategy had no significant effect on defense logistics performance.

In the past, several experimental investigations aiming at characterizing the natural circulation (NC) behavior in test facilities were carried out. They showed a variety of flow patterns characterized by an inverted U-shape of the NC flow curve versus primary mass inventory. On the other hand, attempts to reproduce such curves using thermal-hydraulic system codes, showed 10-30% differences between the measured and calculated NC mass flow rate. Actually, the used computer codes are generally based upon nodalization using single U-tube representation. Such model may not allow getting accurate simulation of most of the NC phenomena occurring during such tests (like flow redistribution and flow reversal in some SG U-tubes). Simulations based on multi-U-tubes model, showed better agreement with the overall behavior, but remain unable to predict NC phenomena taking place in the steam generator (SG) during the experiment. In the current study, the CATHARE code is considered in order to assess a NC characterization test performed in the four loops PKL facility. For this purpose, four different SG nodalizations including, single and multi-U-tubes, 1D and 3D SG inlet/outlet zones are considered. In general, it is shown that the 1D and 3D models exhibit similar prediction results up to a certain point of the rising part of the inverted U-shape of the NC flow curve. After that, the results bifurcate with, on the one hand, a tendency of the 1D models to over-predict the measured NC mass flow rate and on the other hand, a tendency of the 3D models to under-predict the NC flow rate.

Objectives: The purpose of this study was to report the effect of complex Korean medicine treatments on Essential Tremor Plus (ET plus) patient aggravated by a traffic accident. Methods: We treated an ET plus patient with complex Korean medicine. The patient's resting tremor and kinetic tremor in both hands intensified after experiencing a traffic accident, with tremor in the left hand being worse than that in the right hand. Effect of complex Korean medicine treatment was evaluated using Fahn-Tolosa-Marin Tremor Rating Scale (FTMTRS), Numerical Rating Scale (NRS), and Beck Anxiety Inventory (BAI). Results: After 26 weeks of treatments (acupuncture, pharmacupuncture, cupping, Iigyeungbyunqi-therapy, and herbal medicine), the FTMTRS decreased from 38 to 15. NRS of Lt. upper limb pain decreased from NRS 9 to 0. BAI score also decreased from 31 to 17. Conclusions: Complex Korean medicine could be used to treat patients with ET plus aggravated by a traffic accident.
