3D 가상현실은 이미 여러 스포츠 분야에서 사용되고 있으며 특히 엘리트운동 선수들의 훈련 등에 적극 활용되고 있다. 주로 심상훈련 효용성을 극대화하기 위해 활용되고 있으며, 이에 따라 3D 가상현실 기술을 기반으로 심상훈련의 가능성, 유용성, 적합성이 여러 연구를 통해 입증되었다. 그러나 최근에는 가상현실에서의 운동이 더 이상 엘리트 운동선수들의 훈련에만 활용되는 것이 아니라 사회체육 등에 활발히 활용되는 추세에 있다. 3D 가상현실에서의 운동의 장점은 안정성이 높으며 외부환경에 대한 제한이 적다는 것이다. 이러한 장점을 고려할 때 이는 노인체육에 잘 활용될 수 있을 것이다. 따라서 본 연구에서는 노인을 위한 가상현실 기반 심상훈련의 활성화를 위해 국내·외 가상현실 관련 연구들이 어떠한 방법으로 연구되었으며 어떤 결과를 도출하였는지 면밀히 고찰하였다. 더불어 본 연구에서는 이러한 선행연구의 결과를 종합하여 추후 가상현실 연구의 활성화를 위한 방향과 후속 연구 과제를 위해 3D 가상현실 심상훈련의 간학문적 접근, 노인의 특성 및 지원요구를 고려한 지원, 습득된 기술의 일반화 및 유지 방안을 고려한 접근 필요성에 대해 제언을 제시하였다.

세계풍력발전협회(GWEC) 2017년도 Global Wind Report에 따르면 전세계 풍력에 의한 발전용량은 2001년도 23,900MW에서 2016년도 486,790MW로 비약적으로 발전하고 있다. 반면 국내 발전원별 총발전량 비중에서 풍력에 의한 발전은 0.2% 불과하다. 국내외 발전원별 정산단가가 풍력으로 전기를 생산하는 데 드는 발전원가가 석유 등 화석연료 발전원가와 같아지는 Grid Parity에 이미 도달하여 풍력발전에 의한 전기의 생산은 더욱 확대될 것이다. 본 연구에서는 전 세계 해상풍력설비의 88%가 위치하고 있는 유럽의 주요 해상풍력발전단지의 선박통항 규정과 어로활동에 대한 기준을 분석하여 향후 국내 해상풍력발전단지 설치 시 선박통항 및 어로활동 기준 설정 시 고려되어야 할 사항을 제시하였다.

2017년 추계에 남해 전선역을 파악하고, 알칼리 인산분해 효소(Alkaline Phosphatase; APase) 활성을 이용하여 제한 영양염과 제한 영양염의 시간적인 변화를 평가하였다. 전선역이 형성된 인근해역의 경우, 용존무기인(dissolved inorganic phosphorus; DIP)의 농도와 용존무 기질소(dissolved inorganic nitrogen; DIN): DIP 비가 각각 0.2 μM 이하와 최대 23.2로, DIP가 제한된 환경임에도 불구하고 Chlorophyll a(Chl.-a)가 0.2 μg/L로 높은 생물생산력을 보였다. APase와 DIP는 중요한 역의 상관관계(r = -0.81; P<0.001)를 보여, DIP가 제한되어진 해역임을 알 수 있 었으며, APase와 Chl-a 관계는 APase의 60%가 식물플랑크톤, 40%가 박테리아 기원인 것으로 평가되었다. 용존태 APase와 입자태 APase의 분포로부터 전선역은 장기간 DIP가 제한된 해역이며, 그 외의 해역은 최근에 DIP 제한이 해소된 것으로 판단되었다. 따라서 전선역에서 APase와 같이 가수분해효소의 측정은 제한 영양염의 시공간적인 변화 특성을 평가할 수 있으며, 전선역에서 생지화학 순환의 이해를 높일 수 있을 것으로 생각된다.

The effects of some essential oils and Sopophora extract on Frankliniella occidentalis adults, Myzus persicae adults, Plutella xylostella larvae, and Spodoptera exigua larvae were investigated. Insecticidal and phytotoxicity activities of emulsion in water formulations containing the active essential oils as active ingredients under laboratory and pot conditions were also tested. Based on these results, NRS-13 and NRS-24 formulations were selected to further assess as follows; the GC and GC-MS analysis on the active essential oils, the quantity analysis of the major components contained in the formulations, their insecticidal activities under pot and field conditions, and their oral, dermal, skin and eye irritation, and fish toxicities. Thus, the NRS-13 (BaechooSaferTM) and NRS-24 (JindiOutTM) formulations could be considered as insecticides for pest control.

A travel destination offers a form of novelty to the traveler since it can provide experiences that are not of the everyday variety. Therefore, a search for novelty is important as a motivation factor when planning leisure trips and vacation activities and to identify travel market segments. This study aimed to examine the differences in demographic characteristics, travel style, and preferred food-related activities in accordance with the level of tourists’ novelty seeking. This study investigated potential tourists using a self-administered questionnaire survey, which resulted in 300 usable questionnaires. The respondents of this study were classified into two groups according to their level of novelty seeking: Active novelty-seeking group and Passive novelty-seeking group. These two groups were significantly different with respect to demographic characteristics, travel style, and preference of food-related-activity experience. The results show that the Active noveltyseeking group tended to have a higher proportion of females and specialized jobs, a higher level of monthly income and education, more frequent travel, and preference for food-related activity experience than other groups. The result of this study will be helpful for the tourist industry, which needs to develop culinary and food-related experience tour programs and travel market segments.

This study introduces the methods to apply and develop the integrated Cost of Quality (COQ) and Time-Driven Activity-Based Costing (TDABC) model for seeking not only quality improvement but also reduction of overhead cost. Inefficient and uneconomical COQ activities can be identified by using time driver which also maximizes the quality improvement for Prevention-Appraisal- Failure (PAF) quality costs. In contrast, reduction of the indirect cost of unused capacity resource using Quality Cost Capacity Ratio (QCCR) of TDABC minimizes overhead cost for COQ activities. In addition, linkage between Overall Equipment Effective (OEE) and Time Driver develops the integrated system of Total Productive Maintenance (TPM) and TDABC model. Lean OEE maximizes when an Unused Time (UT) of TDABC that are TPM losses and lean wastes reduces whereas the TPM Cost Capacity Ratio (TCCR) of TDABC minimizes indirect cost for non-value added TPM activities. Numerical examples are derived to better understand the proposed COQ/TDABC model and TPM/TDABC model from this paper. From the proposed model, process mapping and time driver of TDABC are known to lessen indirect cost from general ledger of comprehensive income statement with a better quality innovation and improvement of equipment.

For maintaining adequate psychometric properties when reducing the number of items from an instrument, item level psychometrics is crucial. Strategies such as low item correlation or factor loadings, using classical test theory, have traditionally been advocated. The purpose of this study is to describe the development of a new short form assessing the impact of low back pain on physical activity. Rasch measurement model has been applied to the International Classification of Functioning, Disability and Health Activity Measure (ICF-AM). One hundred and one individuals with low back pain aged 19-89 years (mean age: 48.1±17.3) who live in the community were participated in the study. Twenty-seven items of lifting/carrying construct of the ICF-AM were analyzed. Ten items were selected from the construct to create a short form. Item elimination criteria include: 1) high or low mean square (out of the range: .6-1.4 for the fit statistics), 2) similar item calibrations to adjacent items, 3) person separation value, and item-person map for potential gap in person ability continuum. All 10 items of the short form fit to the Rasch model except one item (i.e., carrying toddler on back). Despite its high infit and outfit statistics (1.90/2.17), the item had to be reinstated due to potential gaps at the upper extreme of person ability level. The short form had a slightly better spread of person ability continuum compared to the entire set of item. The created short form separated individuals with low back pain into nearly 4 groups, while the entire set of items separated the individuals into 6 groups. The findings prompted multidimensional models for better explanation of the lifting/carrying domain. The item level psychometrics based on the Rasch model can be useful in developing short forms with rationally retained items.

The purpose of this study is to implement and develop the integrated Economic Value Added (EVA) and Time-Driven Activity-Based Costing (TDABC) model to seek both improvement of Net Operating Profit Less Adjusted Tax (NOPLAT) and reduction of Capital Charge (CC). Net Operating Profit Less Adjusted Tax (NOPLAT) can be maximized by reducing the indirect cost of an unused resource capacity increased by Cost Capacity Ratio (CCR) of TDABC. On the other hand, Capital Charge (CC) can be minimized by improving the efficiency of Invested Capital (IC) considered by Weighted Average Cost of Capital (WACC) of EVA. In addition, the integrated system of TDABC using Balance Scorecard (BSC) and EVA is developed by linking between the lagging indicators and the three leading indicators. The three leading indicators include customer, internal process and growth and learning perspectives whereas the lagging indicator includes NOPLAT and CC in terms of financial perspective. When the Critical Success Factor (CSF) of BSC is cascading as a cause and an effect relationship, time driver of TDABC and capital driver of EVA can be used efficiently as Key Performance Indicator (KPI) of BSC. For a better understanding of the proposed EVA/TDABC model and BSC/EVA/TDABC model, numerical examples are derived from this paper. From the proposed model, the time driver of TDABC and the capital driver of EVA are known to lessen indirect cost from comprehensive income statement when increasing the efficiency of operating IC from the statement of financial position with unified KPI cascading of aligned BSC CSFs.

The purpose of this research is to implement and develop the Economic Cost Driver Size(ECDS) extended model to determine the optimal cash driver size with measurement complexity cost and allocation fail cost. ECDS model can be used to seek both measurement accuracy and time efficiency of the Activity-Base Costing (ABC). The study also develops Activity Priority Number (APN) to evaluate the importance of nonvalue-added activities improvement and to determine the representative cost driver of value-added activities when applying ECDS model. APN consists of Severity Priority Number (SPN), Undetectablitiy Priority Number (UPN) and Occurrence Priority Number (OPN). APN can be obtained from lower-stream activity, current activity, upper-stream activity in terms of hierarchical dependency of SIPOC (Supplier, Input, Process, Output, and Customer). In order to seek both efficiency of invested capital and reduction of overhead cost, the paper proposes the integrated ABC and Economic Value Added (EVA) model using redesigned ABC-based statement of comprehensive income and EVA-based statement of financial position. For a better understanding of the proposed ABC-EVA integrated model, numerical examples are demonstrated in this paper. Cost drivers of ABC and capital drivers of EVA in the proposed model can be used to reduce activity overhead cost from ABC-based statement of comprehensive income and to lessen activity capital charge from EVA-based statement of financial position.

This study was carried out to apply an optimized convenient assay, exploiting azo dye-bound chromogenic substrates, to measurement of protease activity. When determined for responses at varying concentrations of two substrates, azocasein and azoalbumin, using 0.5 and 5.0 mg/mL each of bovine pancreas trypsin, 3% azocasein was found to be the most appropriate substrate solution to measure protease activity. Compared with a conventional casein-Folin phenol assay, the chromogen-based protease assay exploiting 3% azocasein showed better precision to have a coefficient of variability in seven repetitive measurements less than 1.11%. When various reagent-grade and industrial proteases that showed proteinase or peptidase activities were tested by this assay at increasing enzyme concentrations, typical shape of rectangular hyperbola in activity-enzyme concentration profiles was observed. In addition, the assay of this study was suitable for activity measurement in real samples that were prepared by hydrolyzing wheat gluten and anchovy fine powder with proteases.

Traditional quality control for manufacturing or service sector is not suitable for the quality control of a project as the project is one-time task constrained by time, cost, and quality. To meet the internal and external customers’ requirements, quality

This paper aims to examine the differential degree of the task difficulty presented in high school English activity books. To achive the aim, the researchers analyzed tasks for three levels(high, intermediate, and low) in five English activity books currently published based on the revised 7th National Curriculum for high school freshmen. The criteria utilized for grading task difficulty are modified from Ellis(2003a, 2003b) which were developed to account for task complexity in terms of input, conditions, processes and outcomes. The results revealed that in general, the tasks of the activity books were organized in the sequential order of difficulty from low, imtermediate to high proficiency, but the difference of task difficulty across the three proficiency levels was not significant. It was also discovered that among three main factors determining task difficulty, task condition, task process, and task outcomes, task process and required task outcomes were more frequently adopted to di fferentiate the task difficulty level. In addition, there was lack of communicative tasks integrating four language skills (listening, speaking, reading, and writing) in all the five activity books. Further study suggesiotns and limitations are followed.
