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.
This study was done to compare the breast-feeding primiparas' perceptions of their babies with bottle-feeding primiparas' at 2-3 days after delivery. The subjects of this study included 42 breast-feeding mothers and 56 bottle-feeding mothers. Data were collected by using the Neonatal Perception Inventory(NPI) devised by Broussard (1963) and added by Lee, Ja Hyung(1986) from December, 1996 to June, 1997. The results of this study are as follows, 1. Primiparas' perceptions of their babies according to their general characteristics. 1) There was no significant difference in mothers' perceptions according to mothers' age and whether they have a job or not. 2) There was a difference in mothers' perceptions according to their educational level (P<0.1). 2. The comparisons of breast-feeding mothers' perceptions of their babies with bottle-feeding mothers'. 1) There was no significant difference in the two groups' perceptions of other babies 2) There was no significant difference in the two groups' perceptions of their own babies. (1) Breast-feeding mothes' general perceptions of their own babies were better than bottle-feeding mothers', but there was no significant difference between the two groups. (2) Breast-feeding mothers' perceptions about the basic needs of their own babies were better than bottle-feeding mothers', and there was a significant difference between the two groups (P<0.05). (3) Breast-feeding mothers'perceptions about the sense and motor abilities of their own babies were better than bottle-feeding mothers', but there was no significant difference between the two groups. (4) Breast-feeding mothers' perceptions about the necessary care of their own babies were lower than bottle-feeding mothers', but there was no significant difference between the two groups. 3) There was no significant difference between the two groups' positive-negative perceptions of their babies (1) 69% of breast-feeding mothers and 69.9% of bottle-feeding mothers had positive perceptions about general conditions, but there was no significant difference between the two groups (2) 57.1% of breast-feeding mothers and 46.4% of bottle-feeding mothers had positive perceptions about the needs of babies, but there was no significant difference between the two groups. (3) 50% of breast -feeding mothers and 48.2% of bottle-feeding mothers had positive perceptions about the sense and motor abilities of babies, but there was no significant difference between the two groups. (4) 57.1% of breast-feeding mothers and 60.7% of bottle-feeding mothers had positive perceptions about the necessary care for babies, but there was no significant difference between the two groups. 3. 54.8% of breast-feeding mothers tried to feed their own babies on the 1st day after delivery. 83.3% of breast-feeding mothers chose the feeding method for themselves. Only 9.5% of breast-feeding mothers took recomendations for breast-feeding from nurses. 78.6% of breast-feeding mothers had no chance to learn about breast-feeding. 69% of breast-feeding mothers complained about the difficulties of breast-feeding. The most serious problems were : 'insufficient milk supply', 'lack of knowledge about feeding technique' and 'problems with nipples'.

This study aims to identify the relationship between climatic factors and stand mean Diameter at Breast Height (DBH) for two major tree species; Pinus densiflora and Quercus mongolica in Andong-dam basin. Forest variables such as age, diameter distribution and number of trees per hectare from the $5^{th}$ and $6^{th}$ National Forest Inventory data were used to develop a DBH estimation model. Climate data were collected from six meteorological observatory station and twelve Automatic Weather System provided by Korea Meteorological Administration to produce interpolated daily average temperature map with Inverse Distance Weighting (IDW) method. Andong-dam basin reflects rugged mountainous terrain, so temperature were adjusted by lapse rate based correction. As a result, predictions of model were consistent with the previous studies; that the rising temperature is negatively related to the growth of Pinus densiflora whereas opposing trend is observed for Quercus mongolica.

Background: Prevalence of depression comorbid with neurologic disorders such as Alzheimer' disease (AD), Parkinson's disease (PD) and vascular dementia (VD) is higher than that of primary depression. Antidepressant medications, suggested by many researches for depression comorbid with neurologic disorders such as AD, PD and VD, are mainly selective serotonin reuptake inhibitors (SSRI). Objective: The primary objective of this study is the evaluation of antidepressant drug therapy for AD, PD and VD. Method: This study was a retrospective study based on medical records, carried out for 3 years and 6 months (Jan. 2007~Jul. 2010). Patients, diagnosed as comorbid depression through Beck Depression Inventory (BDI), Cornell Depression Scale (CDS), Geriatric Depression Scale (GDS) among neurologic out-patients of Chungnam National University Hospital because of AD, PD and VD, were selected. The results were evaluated by efficacy and safety of antidepressant drug therapy. Results: In result, the prescribing rates of antidepressants were 30%, 55% and 40% for each AD, PD and VD. Depression cure rates of patients receiving antidepressants vs patients not receiving antidepressants were 40% vs 39%, 33% vs 23% and 38% vs 30% for AD, PD and VD. The frequencies of prescriptoin of SSRI were 21%, 11% and 27% for each AD, PD and VD. The frequencies of prescriptoin of benzodiazepine (BZD) was 61%, 82% and 61% for each AD, PD and VD. The ratio of single BZD prescription was more than that of combination prescription of antidepressants. Tricyclic antidepressants (TCA) were rarely prescribed. The rate of patients with BZD-related side effects was 54%. The most frequent side effects of BZD were dizziness (30%), drowsiness (21%) and headache (16%). Side effects of SSRI were rare. Conclusion: In conclusion, the frequencies of prescription of antidepressants were not common for AD, PD and VD. There was little difference in depression cure rate between patient receiving antidepressants and not receiving. Even though SSRI has to be the highest priority of usage, the frequencies of prescription of SSRI were lower than those of BZD. Additional researches and efforts are required to improve antidepressant drug therapy for neurologic disorders such as AD, PD and VD.
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.
Properties of discontinuity for Seoul Granite in northeastern part of Seoul City were analyzed by dividing structural domains into Surak and Bulam Mtn. areas. Important parameters measured among several engineering properties of a rock during tunnel excavation and road construction are as follows: 1) Orientation of joint, 2) joint spacing, 3) joint density, and 4) uniaxial compressive strength. Orientation, spacing, and density of joints can be directly measured during field investigation using scanline survey, circle-inventory method, and window survey. Uniaxial compressive strength of the rock was calculated by a simple correlation equation although it is originally necessary to prepare core samples in measuring it. Major orientations of joints measured from both areas are 3 sets of joints with different orientations. In other words, they are 2 sets of orthogonal joint and 1 set of sheet joint that is dipping at low angle, and have very similar orientations in both areas. Joint densities in both areas range from 0.039 and 0.066/cm, and average joint length are between 1.30 and 4.52m. Average joint spacing also has values from 10.3cm up to 59.6cm, and shows significant difference along specific orientation of scanlines measured. Values of uniaxial compressive strength calculated on the basis of Schmidt hammer rebound values range from 217 to 335 MPa, which indicates very strong rock type by classification of wall strength.
Types of slope failure related to cut slope stability are interpreted through case analyses, and also factors affecting structurally controlled instability investigated, which are developed by geologic structures along a national road No. 25 across the Cheongwon and Boeun-Guns, Chungbuk. Engineering properties such as orientation, persistence, roughness and uniaxial compressive strength of joints are analyzed by square-inventory method in three areas with well-preserved outcrops. The study area is located in Ogcheon folded bet, and are composed of quartz-schist and quartzite in the Midongsan Formation and phyllite in the Ungyori Formation. Flexural beds by folding, schistosity and cleavage besides joints are developed due to slight metamorphism. Various types of joints developed by folding are formed such as strike-parallel, strike-perpendicular, wedge and wrench joint sets by both initially regional and later superposed folding. Factors of slope instability are created by crossing the orientations of joint, cleavage, bedding and slope one another. In the case that the orientation of a slope is coincident with one of beds, factors causing large-scale failure including plane failure are increased greatly. Also in the region that orientations of the slope and bed are crossed each other at high angle, only local and minor failures are shown in the slope.

Greenhouse gas(GHG) inventories and basic strategies for Jeonbuk regional government were established to reduce greenhouse gas emissions. The method to construct GHG inventories of Jeonbuk followed the 'Revised IPCC 1996 Guidelines'which was used for the 'Third National Communication of the Republic of Korea under UNFCCC'. Korean government could use primary energy consumption for the energy industries section in the national GHG inventories. However, regional governments should use secondary energy consumption (included electricity consumption) for the energy industries section for their GHG inventories because they could not control the emission of energy transformation section. In the result of Jeonbuk GHG inventories in 2006, carbon dioxide($CO_2$) emissions from fuel combustion covered 87.1% of total emissions. Methane($CH_4$), carbon dioxide($CO_2$) from other sections, nitrous oxide($N_2O$) and F-gas(HFCs, PFCs, $SF_6$) accounted for 8.1, 2.2, 1.6 and 1.0% of total emissions, respectively. The sectional emission decreased in the order of the energy(88.0%), agriculture(7.6%), waste(2.3%) and industrial processes(2.1%) section. The energy industries section that contained electricity consumption was the most dominant emission source in the energy section. F-gas consumption, rice cultivation and waste incineration were main emission sources in the industrial processes, agriculture and waste section, respectively. In this study, basic directions of each section were established by the results of Jeonbuk GHG inventories in 2006.
Harvested wood products (HWP) are known as products from the tree such as sawn wood, plywood, particle board, structural lumber, wooden interior material, wooden furniture, and paper products. Because carbon is locked up in the HWP until eventual end-use of HWP, HWP played a role as the carbon storage which has the effect of stabilizing the concentration of carbon dioxide in the atmosphere. For these reasons, the suggestion that it must admit the carbon storage effect of HWP has been constantly raised. In 2011, the 17th session of the Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC) which was held in Durban, South Africa, assigned "Production Approach" which targets only the HWP producted by using round wood of domestic forestry as a official method for carbon accounting. Therefore, it is necessary that each country has to determine the half-life of wood in order to correspond to the discussions and negotiations between countries in the future and to develop an inventory of product-specific domestic wood. In this study, some countries' examples of the methods and conditions for determining half-life of HWP were investigated, and it was tried to derive the factor and methodology to determine half-life span of domestic HWP appropriately.
Asian Americans are one of the fastest growing minority groups in the United States. One of the stereotypes associated with Asians is that they are more likely to choose careers in science, medicine, and engineering rather than social science, inclusive of social work, mass communication, or humanities (Leong & Serafica, 1995; Tang et al., 1999). This occupational stereotyping of Asians is not just a myth in that only a few Asians choose social work as a career (Lennon, 2005; NASW, 2006). Few studies exist on Asian Americans who do not choose Asian stereotypical career choices, such as social work. Acknowledging this lack of research, the present study was developed to explore the relationships between factors that may influence Asian Americans who choose social work as their career. Based on Social Cognitive Career Theory (Lent, Brown, & Hackett, 1994), it was hypothesized that acculturation and family immigration status influenced parental involvement, disapproval by significant others as a perceived career barrier among Asian American social workers. A cross-sectional survey design was used in this study. The sample was derived from the members'database of the National Association of Social Workers (NASW). A total of 900 were randomly chosen among 1,802 of Asian American social workers in the NASW database, and 370 Asian American social workers participated in this study with 41 percent of a return rate. Quantitative data were collected through standardized measurements: Suinn-Lew Asian Self-Identity Acculturation Scale (Suinn, Rickard-Figueroa, Lew, & Vigil, 1987); Career Barriers Inventory Revised (Swanson, et al., 1996); and eight items from Tang et al.'s (1999) Asian American Career Development Questionnaire. The data were collected through a combined method of an online survey with option of a paper mail-return questionnaire. Results of the study found significant group differences among family immigration status groups on parental involvement, and perceived likelihood and hindrance of disapproval by significant others. The group of the 2nd generation reported the highest scores of parental involvement among the family immigration status groups. Also, Asian American social workers who represented the 3rd and higher generation of immigration reported lowest perceived likelihood and hindrance scores of disapproval by significant others. However, there was no significant multivariate effect of acculturation on parental involvement, and perceived likelihood and hindrance of disapproval by significant others. Implications and limitations of this study, as well as suggestions for future research, are discussed.
