Objective : The purpose of this study was to define a standard score of Sensory Processing Scale for Children (SPS-C) and its concurrent validity by correlation with the Short Sensory Profile (SSP). Methods : The subjects were children enrolled in nurseries and kindergartens in Busan and Gyeongnam. We defined the standard score of the SPS-C and identified its concurrent validity for 337 children. Both the SPS-C and SSP instruments were used to assess the children's sensory processing ability. The collected data were analyzed using SPSS 24.0. A statistical analysis was used to define the standard score for SPS-C based on the mean and SDs of -1 and -2. To identify the concurrent validity of the SPS-C, the correlation between it and SSP was measured using Pearson's correlation analysis. Results : The ranges of total standard scores on the SPS-C were classified as follows: 115~160 indicated "Typical Performance"; 105~114 indicated "Probable Difference"; and finally, 50~104 indicated "Definite Difference." Concurrent validity was ascertained using the Pearson correlation between the total scores of the SPS-C and the SSP; the Pearson correlation coefficient was .755, indicating a statistically significant correlation. Conclusion : This study suggests the standard score of the SPS-C for interpreting results in clinical settings and confirms that it is a valid tool for evaluating children's sensory processing ability.

It is expected that logistics standardization have an great effect on industry and national economy due to cost saving and improving efficiency. Therefore all countries of the world make a strenuous effort to take a lead of logistics standardization Despite such efforts of every country, our country remained a lukewarm attitude about logistics standardization. Especially, our country remained a lukewarm attitude about logistics standardization effect quantify. We have to suggest the necessity of standardization and the effect for carrying out logistics standard. So, this study performed literature review and case study for development of effect valuation method. Also, this study developed effect valuation standard for quantifiable standardization effect and drew the effect valuation standard model. First, the measure of preliminary effectiveness was chosen for MOE selection. As a results, vehicle load ratio, delivery cost, keeping space efficiency warehouse automation ratio, etc. were selected. Then, vehicle/truck load ratio, warehouse keeping efficiency, up unloading hour, packaging cost, consistency transportation ratio were chosen for MOE of pallet standardization.

표준강수지수(Standardized Precipitation Index, SPI)는 강수량 변동의 정도를 표준화하여 나타낸 지수로, 가뭄 평가에 적용되고 있다. 일반적으로 SPI를 산정할 때는 월 단위의 시간 척도를 적용하며, 장기간의 가뭄에 대해 평가한다. 그러나 시간 척도가 길어질수록 가뭄 발생 후 가뭄을 감지하는 데 걸리는 시간이 더 길어지기 때문에 대처가 더욱 어려워진다. 또한, 기후변화로 인해 가뭄 빈도가 증가하고, 그 정도가 더욱 심화되면서 일 단위의 적용이 필요해지고 있다. 본 연구는 한반도 남부지역을 대상으로 일 단위의 SPI 적용을 위한 최소 시간 척도를 조사하였다. 대상 지역을 강원권, 수도권, 부울경, 대경권, 호남권, 충청권의 총 6개 지역으로 분리하여, 각 지역별, 계절별 최소 시간 척도를 조사하였다. SPI 산정을 위해 후보 분포형으로 Gumbel, Gamma, GEV, Loglogistic, Lognormal, Weibull을 적용하였으며, 시간 척도는 5일부터 365일까지 총 10개로 설정하였다. 본 연구에선 크게 적합도 검정과 정규성 검정으로 진행하였다. 적합도 검정에서는 Chi-square test를 적용하였으며, 이때 일 단위의 짧은 시간 척도를 적용할 경우 누가 강수 시계열의 값이 0으로, 0값이 시계열에 포함되면 SPI의 정확도가 떨어지는 문제가 발생하는데, 이를 보완하기 위해 누가 강수 시계열의 0값을 고려하였다. 마지막으로 각 후보 분포형을 적용하여 산정된 SPI가 표준정규분포에 합당한지를 검증하기 위해 Anderson-Darling test를 수행하였다. 결과적으로 대부분의 지역에서는 봄과 여름의 경우 최소 15일 정도의 시간 척도까지는 적용할 수 있을 것으로 판단되며, 겨울의 경우는 최소 30일 정도의 시간 척도를 적용해야 함을 확인하였다. 지역별로 차이가 크진 않지만, 이러한 연구 결과를 참고하여 각 지역별로 더 나은 가뭄 대책을 마련할 수 있을 것으로 기대된다.

본 논문에서는 퍼지 클러스터링 알고리즘에 의해 구해진 퍼지 클러스터들에 대한 평가척도를 제안한다. 제안된 척도는 퍼 지 클러스터들간의 중첩성(overlapping)과 분리성 (separation)을 이용한다. 중첩성은 클러스터간 인접도를 이용하여 계산하며, 분리성은 데이터에 대한 상관성 정도를 나타낸다. 따라서 중첩성이 낮고 분리성이 높을수록 좋은 클러스터 결과라고 할 수 있다. 표준 데이터 집합을 대상으로 기존의 척도들과 비교실험 함으로써 제안된 척도의 신뢰성을 알아보았다.

In the current marketplace, there are maturity models, standards, methodologies and guidelines that can help an organization improve the way it does business. All SPI models including ISO/IEC I5504 and CMMI provide the capability level of software process. However, most available improvement models focus on a specific goals and Practices of the processes So my assessors need an objective process measure how to estimate achievement of goals and practices. We proposed quantitative process capability metric (PCM) which can determine the degree of capability And the effective measuring approach help SPI assessor as well as organization unit.

This study deals with 8-cheok(ch"), equivalent to 2.4m as the standard scale of architectural module in Korea. 8ch" of Korean module was a unique dimensions compared to other East-Asian architecture. It is inferred that it spread in Joseon Dynasty by the effects of the law which limited the size of buildings and materials according to social rank. 8ch" module was applied to the Palace architecture and the highest grade mansions rather than common and small houses. The application of 8ch" module changed the process of architectural planning, and bred the essential characteristics of Korean architecture in terms of appearance and techniques. In addition, it developed to gain multiformity of composition by combination of other modules.

This study aims to develop the corporate philanthropy scale focusing on the guidelines of ISO26000 and to test its reliability and validity. For the purpose of this study, author conducted focus group interview, individually interview, consult and pilot test in order to clarify description and relevance of scale items. To test reliability and validation of scale, 94 staffs in charge of the corporate philanthropy work in the companies were surveyed as research subjects. The results of the explanatory factor analysis on scale found the six factor structure and 27 items. The construct validity and discriminant validity were confirmed through the confirmatory factor analysis. The reliability of the scale also remained at a high level. Based on these results, implications for corporate philanthropy was suggested.

The purpose of present study was to develop the Korean Version of Luria-Nebraska Neuropsychological Battery for Children(LNNB-C), to examine the reliability of it, and to establish the norms for determining the probability of brain damage. The normative group used to standardize the Korean version of LNNB-C was composed of 147 children between the age of 8 and 12(body 74, girl 73). The clinical group consisted of 19 brain damaged, 16 ADHD, and 16 psychiatric controls. The inter-scorer reliability was 96.3%, indicating that the stability of the scoring system for the Korean version of LNNB-C is good. The reliability coefficients(Cronbach's ${\alpha}$) of LNNB-C scales were ranged .51 to .91, which are similar to those of original LNNB-C. To establish the norms for detecting brain damage, the means and standard deviations for normative group were used to calculate T-scores for each scale. To determine a critical level that could successfully predict a normal child's average score at a given age, first the average score of normative group was calculated, and this score was then entered a regression equation with age to predict the average(baseline) acore. Finally, some issues on constructing the Korean version of LNNB-C and the cultural differences between Korean and American children in performing LNNB-C were discussed.
