BACKGROUND/OBJECTIVES: The purpose of this study was to evaluate the feasibility of application of the draft nutritional standards for school lunches in the Republic of Korea (South Korea) from the supplier perspective. SUBJECTS/METHODS: In November 2018, a pilot operation was conducted at 104 participating schools for 2 weeks each by applying the draft standards A and B. To evaluate the ease and appropriateness of application of the standards, we analyzed the nutritional values and food cost of the school lunches for 2 weeks before and for 4 weeks under the pilot operation. We conducted an online survey of school dietitians or nutrition teachers of the participating schools to evaluate the feasibility of application of the standards in school lunch sites. RESULTS: The proportions of schools of which lunches met the reference values of the school's own nutritional standards were 19.2% for the standards A and 21.2% for the standards B. The food cost of school lunches applying the standards A (KRW 2,880) was significantly lower than that of school lunches applying the standards B (KRW 3,030) or the existing standards (KRW 2,980). As a result of the survey, the mean score for the ease of application was significantly higher for the standards B (2.75) than for the standards A (2.24). The proportions of school dietitians or nutrition teachers reporting no problem in meeting an existing food cost standard were 72.5% for the standards A and 61.8% for the standards B, respectively. The overall appropriateness of application was higher for the standards B, because almost two-thirds (58.8%) of the respondents answered that the standards B were more appropriate than the standards A. CONCLUSION: The standards B were more feasible to apply as nutritional standards for school lunches than the standards A from the supplier perspective.

In order to know what sorts of features of neck form may be required to make plans for tight collars, the neck form of young japanese women were measured three demension-ally using GRASP(Grating Projection System for Profiling) and plaster torso. By the BASIC language in NEC computer and EXCEL program in MACINTOSHI computer, it became possible to draft a number of neck surface auomatically, therefore, we got analysis of a mass of subjects. Thed following results were obtained: 1. There was a large individual difference in the shape of neck, in particular, on the front and side curves of the neck base line, where the undulation of clavicular part of neck and inclination of shoulder are refracted. 2. When designing a stand collar, from the viewpoint of clothing strcture, it is important to grasp exactly the shapes of the neck, such as the line of the neck base, the neck gradient, back neck length, back neck width & girth. 3. According to the somatotypes(turing-over, standard, bending type), there were different the method of the basic collar pattern making.

This work presents numerical results, using OpenFOAM, of the flow in the swirl flow generator test rig developed at Politehnica University of Timisoara, Romania. The work shows results computed by solving the unsteady Reynolds Averaged Navier Stokes equations. The unsteady method couples the rotating and stationary parts using a sliding grid interface based on a GGI formulation. Turbulence is modeled using the standard k-${\varepsilon}$ model, and block structured wall function ICEM-Hexa meshes are used. The numerical results are validated against experimental LDV results, and against design velocity profiles. The investigation shows that OpenFOAM gives results that are comparable to the experimental and design profiles. The unsteady pressure fluctuations at four different positions in the draft tube is recorded. A Fourier analysis of the numerical results is compared whit that of the experimental values. The amplitude and frequency predicted by the numerical simulation are comparable to those given by the experimental results, though slightly over estimated.

통합 음성/오디오 부호화기 (Unified Speech and Audio Coding, USAC)는 2011년 MPEG에서 FDIS (Final Draft International Standard)를 승인받은 최고 성능의 통합 음성/오디오 부호화기이다. 전통적으로 MPEG에서는 복호화기 기술만 표준화하므로 인코더 기술에 대한 고찰이 쉽지 않을 뿐 아니라, 예제로 공개하는 인코더 (Reference Model, RM)의 경우에도 기본 아이디어만을 포함하고 있기 때문에 이를 사용할 경우 성능 저하가 매우 심각하다. 성능 열화는 매우 심각하다. 이러한 문제를 최소화하기 위해 오픈 소스 기반으로 진행되고 있는 프로젝트 JAME에서는 USAC에 적용된 핵심 인코더 기술의 성능을 최대화 할 수 있는 방법을 제안하고 있다. 본 논문에서는 입력 신호에 따라 두 코더가 선택적으로 동작되게 하는 신호 분류기와 심리 음향 모델을 기반으로 하는 주파수 부호화 기술, 그리고 전이 윈도우 기술 등의 주요 인코더 기술들에 대하여 소개한다. 또한 FDIS를 위한 verification test 결과와 Common Encoder의 성능 평가를 덧붙인다.
