Relations of factors associated with burnout were investigated among 124 child protective service workers currently working in Korean Child Abuse Prevention Centers nationwide. Three categories of factors associated with burnout were examined; (1) individual characteristics, (2) job-related characteristics, and (3) job-satisfaction. Social survey method using questionnaires by mail was employed. MBI(Maslach Burnout Inventory) for measuring burnout, a part of Smith, Kendal & Hulin's JDI(Job Description Index) for job-satisfaction, and a scale measuring the special characteristics of job developed by researchers were used. Mann-Whitney test and Kruskal-Wallis test were employed to analyze the data. Across all burnout sub-scales(emotional depletion, dehumanization of clients, lack of feelings of achievement), subjects reported a high degree(above the cutting point) of burnout. Several factors were identified as associated with burnout. Child protective service workers who are young, single with front line worker status reported higher burnout. Lack of education and training before the job location were another factors which contributed to worker burnout. Lack of proper supervision stood out as another burnout provoking factor. Job-satisfaction was negatively correlated with all three burnout sub-scales, which meant the lower the job-satisfaction, the higher the burnout of service workers. The findings implicate that the administrators of Child Abuse Prevention Centers should pay close attention to their workers' sign of burnout and develop carefully designed support system which include provision of excellent supervision, proper education and training opportunities and organizational effort to strengthen employees' overall job-satisfaction to secure their quality of services toward abused children and their family.

Compendium of arithmetic, geometry, and proportions and proportionality' that was published in Venice in 1494 has been recognized as the first bookkeeping data in the world. Major characteristics of Pacioli's bookkeeping rules were reviewed in this study as follows: All the necessary particulars for double entry bookkeeping were provided in Pacioli's bookkeeping rules;. List of property was described at the time of start of business; Three major books were used; Details of daily transactions were considered to be important; Strike through was lined at each description in journal books, details of daily transactions, and list of property after entry of ledger; Amount columns were provided and Arabic numerals were used; Annual settlement custom was being initiated; Profit and loss account was prepared at year-end; Trial balance sheet was inevitably described; Books were verified prior to closing accounts; Control account was not established; Financial statements were not prepared and business analysis was made, too; Finished goods inventory was not adjusted; Mark was assigned to books; Inter-office account was prepared; Branch accounts and branch ledgers were prepared; There was entries of trust; Current arrangement was described; The principle 'Cost or market price, whichever is lower basis' was promoted: Petty cash system is explained Checks and bills of exchange are used in bank account. As mentioned, characteristics of Pacioli's bookkeeping rules were reviewed; the signs of necessity for preparation of profit and loss statement and balance sheet is found as well as preparation of trial balance sheet and the rules may be considered as a very excellent one in terms of the bookkeeping on initiating stage of double entry bookkeeping.
The periodic square wave (PSW) model was successfully applied to the optimal design of a batch-storage network. The network structure can cover any type of batch production, distribution and inventory system, including recycle streams. Here we extend the coverage of the PSW model to multitasking semi-continuous processes as well as pure continuous and batch processes. In previous solutions obtained using the PSW model, the feedstock composition and product yield were treated as known constants. This constraint is relaxed in the present work, which treats the feedstock composition and product yield as free variables to be optimized. This modification makes it possible to deal with the pooling problem commonly encountered in oil refinery processes. Despite the greater complexity that arises when the feedstock composition and product yield are free variables, the PSW model still gives analytic lot sizing equations. The ability of the proposed method to determine the optimal plant design is demonstrated through the example of a high density polyethylene (HDPE) plant. Based on the analytical optimality results, we propose a practical process optimality measure that can be used for any kind of process. This measure facilitates direct comparison of the performance of multiple processes, and hence is a useful tool for diagnosing the status of process systems. The result that the cost of a process is proportional to the square root of average flow rate is similar to the well-known six-tenths factor rule in plant design.
Purpose: Pain is the most common and influential symptom in cancer patients. Few studies concerning pain intensity in the terminally ill cancer patients have been done. This study aimed to identify factors related with more than moderate pain. Methods: This study used secondary data of 162 terminal cancer inpatients at the palliative ward of six training hospitals in Korea. Physician-assessed pain assessment was by 10 point numeric rating scale. Substantial pain was defined more than moderate intensity by the Korean National Guideline for cancer pain. The Korean version of the MD Anderson Symptom Inventory was self-administered to assess symptoms. Survival prediction was estimated by the attending physicians at the time of admission. Results: Less than six weeks of predicted survival and more than numeric rating of six for worst drowsiness in the previous 24 h were significantly related to substantial pain (P=0.012 and P=0.046, respectively). The dose of opioid analgesics was positively related to substantial pain (P=0.004). Conclusion: Factors positively related to substantial pain were less than six weeks of predicted survival and considerable drowsiness. Careful monitoring and active preparation for pain are required in terminal cancer patients having those factors.
Korean government is enforcing 'Greenhouse gas target management' in order to achieve Greenhouse gas reduction target. To attain Greenhouse gas reduction target, companies in Korea must establish their GHG inventory system and analysis their GHG emissions characteristics for deduction of mitigation measures. LMDI(Log Mean Divisia Index) decomposition analysis is widely used to understand characteristics of GHG emission and energy consumption. In this paper, the characteristics of GHG emission from the line of railroad in Korea is respectively analyzed in terms of conversion effect, intensity effect, production effect and distance effect. Data of railroad GHG emission from 2000 to 2007 are used. As a result, total effect of railroad's GHG emission is $96,813tCO_2eq$. Production effect ($39,865tCO_2eq$) and distance effect ($327,923tCO_2eq$) affect increase of railroad GHG emissions while Conversion effect ($-158,161tCO_2eq$) and intensity effect ($-112,814tCO_2eq$) influence decrease of the emissions.

Purpose : We aimed to validate a new manual therapy to treat tension type headache(TTH) by applying myofascial release techniques to the scalp and to examine the changes in the quality of life and the headache characteristics after treatment and at the 6-month follow-up. Methods : Thirty patients were recruited in this study and were assigned to two groups through simple random sampling. Fifteen patients were assigned to the manual therapy group (MT) and 15 patients to the scalp myofascial release technique (SMT) group. However, five patients from the MT group and one from the SMT group were excluded. Therefore, 24 patients with TTH (10 males, 14 females) participated in the study. Patients underwent either MT or SMT. The procedures were performed by a physical therapist twice per week for 4 weeks. The quality of life [using the brief pain inventory (BPI) and the headache impact test (HIT)], and the frequency, duration, and intensity of the headache [on a visual analog scale (VAS)] were assessed before and after the treatment, and at the follow-up. Results : After 4 weeks of SMT, the frequency (p<.001), duration (p<.05), and intensity (p<.001) of the headache and the quality of life (HIT; p <.001, BPI; p<.001) significantly improved in the patients with TTH. The improvement in these parameters remained significant even after 6 months of follow-up. Similarly, After 4 weeks of MT, the frequency (p<.05), duration (p<.05), and intensity (p<.01) of the headache, and the quality of life (HIT; p<.05, BPI; p<.001) significantly improved in the patients with TTH. The improvement in these parameters remained significant even after 6 months of follow-up. There was no significant difference in these parameters between the two groups. Conclusion : It has been suggested that MT using the SMT can be used as a non-invasive treatment to treat the frequency, duration, and intensity of the TTH, and to improve the quality of life.
The aim of this study was to distinguish 3 concepts(capacity, capability, and performance) for the motor activities of children with cerebral palsy(CP) and examinate relation between capacity(can do in a standardized environment), capability(can do in daily environment), and performance(does do in daily environment). Cross-sectional analysis with a assessment record of children with CP (n=40; 19males, 21 females; mean age 6y 6mo, SD 3y 8mo) was performed. Levels of severity according to the Gross Motor Function Classification System(GMFCS) included level1(13%), level2(10%), level3(43%), level 4(33%), and level 5(3%). Motor activities capacity was assessed by the Gross Motor Function Measure (GMFM-66). Capability and performance were assessed using 2 scales(functional skill, caregiver assistance) of the Pediatric Evaluation of Disability Inventory(PEDI). Correlations between capacity and capability was 0.811(p < .05), and between capability and performance were high(r=0.711, p < .05). And the correlation between capacity and performance is the lowest(r=0.711, p < .05). Motor performance levels are only partly reflected by the motor capacity and motor capability levels in children with CP. Because performance is influenced by Contextual factors (particularly, social factors such as family function). This study suggests that it is necessary to distinguish and evaluate the capacity, capability, and performance in children with cerebral palsy.

Objective : The aim of this study was to examine the relationship between occupational stress and depression, as it is seen to be corresponding with the work characteristics of local government officials. Methods : The data of 671 local government officials who participated in this study from July to December 2015 as a part of an occupational stress management program, were analyzed retrospectively in this study. Likewise, the participants completed questionnaires, including a short form of the Korean Occupational Stress Scale (KOSS), and the Beck Depression Inventory-II (BDI-II) the results of which were evaluated and reviewed. Results : The study noted that the subscales of occupational stress related to depression were varied, according to the work characteristics of the participants, after adjusting for age and job grade. It was found that the participant's variables of job insecurity, lack of reward, organizational system and occupational climate were significantly related to the development of a depressed mood in the participant in a general sense. Notably, the factor of interpersonal conflict was significantly related to depressed mood among the general administrative group; meanwhile, lack of reward in the welfare group and insufficient job control in the technical group were significantly associated with the likelihood of developing a depressed mood in participants reviewed. In the operation and maintenance of facilities group, job insecurity was significantly related with depressed mood, whereas job demand was related more with the incidence of depression in the field work group. Conclusion : This study revealed that the influence of occupational stress on depression varied according to the occupational characteristics experienced by the participants in the work environment. These findings may be used to enhance the occupational stress management program for local government officials according to their work characteristics, to bring awareness to this issue.

Forest canopy height is an indispensable vertical structure parameter that can be used for understanding forest biomass and carbon storage as well as for managing a sustainable forest ecosystem. Plot-based field surveys, such as the national forest inventory, have been conducted to provide estimates of the forest canopy height. However, the comprehensive nationwide field monitoring of forest canopy height has been limited by its cost, lack of spatial coverage, and the inaccessibility of some forested areas. These issues can be addressed by remote sensing technology, which has gained popularity as a means to obtain detailed 2- and 3-dimensional measurements of the structure of the canopy at multiple scales. Here, we reviewed both international and domestic studies that have used remote sensing technology approaches to estimate the forest canopy height. We categorized and examined previous approaches as: 1) LiDAR approach, 2) Stereo or SAR image-based point clouds approach, and 3) combination approach of remote sensing data. We also reviewed upscaling approaches of utilizing remote sensing data to generate a continuous map of canopy height across large areas. Finally, we provided suggestions for further advancement of the Korean forest canopy height estimation system through the use of various remote sensing technologies.

This study was carried out on 455 forest wetlands of south Korea for which an inventory was established through value evaluation and grade. Correlation analysis was conducted to find out the correlation between the types and grades of forest wetlands and 23 evaluation factors in four categories: vegetation and landscape, material circulation and hydraulics·hydrology, humanities and social landscape, and disturbance level. Through the improvement of types and grades of forest wetlands, it is possible to secure basic data that can be used in setting up conservation measures by preparing standards necessary for future forest wetland conservation and restoration, and to found a systematic monitoring system. First, between the type of forest wetland and size and accessibility showed a positive correlation, but the remaining items were analyzed to have negative or no correlation. In particular, it was found that there was no negative correlation or no correlation with the grades of forest wetland. Moreover, it was found that there was a very strong negative correlation with the weighted four category items. Thus, it is judged that improvement is necessary because there is an error in the weight or adjust the evaluation criteria of the value evaluation item, add an item that can increase objectivity. Especially, in the case of forest wetlands, the ecosystem service function due to biodiversity is the largest, so evaluation items should be improved in consideration of this. Therefore, it can be divided into five categories: uniqueness and rarity (15%), wildlife habitat (15%), vegetation and landscape (35%), material cycle·hydraulic hydrology (30%), and humanities and social landscape (5%). It will be possible to propose weights that can increase effectiveness.
