The purpose of this study was to measure concentrations of $K^+$, $Na^+$, $Cl^-$ by ionometer with check salt strip, simple salimeter and Ion-selective electrode (ISE) and compare the results of each mensuration; furthermore, the possibility of inferring the $Na^+$ concentration from $Cl^-$ concentration of urine and the impact of $K^+$ on the concentration of each ion was examined. The results showed that ISE determined $Na^+$ and $Cl^-$ concentrations in the urine are highly interrelated (R=0.9039); in addition, concentrations of $Cl^-$, measured with strip and ISE from urine are highly interrelated (R=0.9338). The concentration of $Na^+$ in urine, inferred by measuring $Cl^-$ concentration with strip, has a high relationship (R=0.8580) with the concentration of $Na^+$ in urine, measured by ISE. The results of our study will increase awareness of $Na^+$ intake and the utility of check salt strip, as well as the possibility of inferred $Na^+$ concentration from measures of $Cl^-$ concentration as a screening test for reducing sodium intake.

Local wall thinning and integrity degradation caused by several mechanisms, such as flow accelerated corrosion, cavitation, flashing and/or liquid droplet impingement, is a main concern in secondary steam cycle piping system of nuclear power plants in terms of safety and operability. Thinned pipe management program (TPMP) has being developed and optimized to reduce the possibility of unplanned shutdown and/or power reduction due to pipe failure caused by wall thinning. In this paper, newest technologies, standards and regulations related to the integrity assessment, repair and replacement of thinned pipe component are reviewed. And technical improvement items in TPMP to secure the reliability and effectiveness are also presented.

The reimaging optics of the KASINICS (KASI Near Infrared Camera System) includes many transparent components like an entrance window, band-pass filters, and blocking filters. As observational targets or in-field background objects, bright stars may cause optical ghosts that can significantly degrade the system performance of the KASINICS. We estimated analytically the relative brightness of ghost components with respect to a point source and examined the effects of tilting optical components as a method of suppressing ghosts. We also performed numerical ray tracings including all the optical components and found the results are consistent with those of the analytic estimations. We conclude that the KASINICS will not suffer from significant ghost effects with appropriate anti-reflection coatings and fittings for the optical components.

Lee's 메뉴엔지니어링 분석법(LME)의 적용 - 이탈리아 피자류를 중심으로 -

이성호,Lee, Sung-Ho 한국식품영양학회 2020 韓國食品營養學會誌 Vol.33 No.1

The purpose of this study is an application of Lee's Menu Engineering (LME) method for menu analysis on the eight kinds of pizza selected from 17 kinds of pizza served by an Italian restaurant near by the Keimyung College University campus. The eliminated nine items were in the third quadrant or below the trend line. The LME method is more efficient than generally used methods such as the Miller, Kasavana & Smith, Uman, Pavesic and Merricks & Jones method. The LME method comprises reference lines and four quadrants created by x, y axes and its average values. The x and y axes comprise the sales ratio (MM%, percentage of the Menu Mix) and the weighted contribution margin (WCM%, percentage of the Weighted Contribution Margin) respectively. The obtained results are such that total sales increased by 1.59% from 58,747,200 won to 59,684,000 won, despite the decrease in sales volume. Total contribution margin also increased from 35,248,320 won to 35,810,400 won. The trend line also shows from y=0.9147x (R²=0.703) to y=0.9944x (R²=0.9893). These results indicate that the LME method is superior in practical applications.

Recent studies clearly demonstrated that the novel expression of LH gene in the rat testis, and suggested the local action of the LH-like molecule. The present study was performed to analyze the expression of LH genes in the rat accessory reproductive organs. Expression of LH subunit genes in the rat uterus and epididymis was demonstrated by reverse transcription-polymerase chain reaction (RT-PCR) and specific LH radioimmunoassay (RIA). The $LH_{beta}$ transcripts in these organs contained the published cDNA structure, the pituitary type exons 1-3, which encoded the entire $LH_{beta}$ polypeptide. Presence of the transcripts for the ${\alpha}$-subunit in the rat reproductive tissues were also confirmed by RT-PCR. In the LH RIA, significant levels of LH were detected in crude extracts from the rat ovary, uterus and epididymis. The competition curves with increasing amount of tissue extracts were parallel with those of standard peptide, indicating that the immunoreactive LH-like materials in these tissues are similar to authentic pituitary LH molecule. In rat epididymis, the highest amount of immunoreactive LH was detected in corpus area. Our findings demonstrated that the genes for LH subunits are expressed in the rat accessory reproductive organs, and suggested that these extrapituitary LH may act as a local regulator with auto and/or paracrine manner.

We have developed a high-speed and high-resolution multimodal nonlinear optical microscope, which can acquire in vivo label and label-free 3D images. Using this microscope, we could successfully observe dynamic images of the zebrafish heartbeat with 33-millisecond intervals without staining process, indicating 1.68 beats per second. In addition, we show that the label-free, high-speed, real-time images can be obtained during somatic cell divisions in the zebrafish’s embryo.

The basic function of HLW disposal system is to prevent excessive radio-nuclides being leaked from the repository in a short time. To do this, many technical standards should be developed and established on the components of disposal system. Safety assessment of a repository is considered as one of technical standards, because it produces quantitative results of the future evolution of a repository based on a reasonably simplified model. In this paper, we investigated other countries' regulations related to safely assessment focused on the assessment period, radiation dose limits and uncertainties of the assessment. Especially, in the investigation process of the USA regulations, the USA regulatory bodies' approach to assessment period and peak dose is worth taking into account in case of a conflict between peak dose from safety assessment and limited value in regulation.

길이방향으로 연속된 래티스를 가지는 철선 트러스데크의 구조 거동

이성호,박형철,오보환,조순보,Lee, Sung Ho,Park, Hyung Chul,Oh, Bo Hwan,Cho, Soon Bo 한국강구조학회 2009 韓國鋼構造學會 論文集 Vol.21 No.1

철선 트러스데크는 기존의 재래식 슬래브 거푸집이나 일반 데크플레이트 공법을 대체하여 철골조는 물론 철근콘크리트 구조물에도 사용이 점차 증가하고 있다. 현재 사용되고 있는 기존의 트러스 데크는 래티스 철선과 하부 철선의 비연속적인 절점간격에 의한 트러스의 비렌딜거동에 의해 완전한 트러스형상에 비해 처짐이 커지는 문제점이 있다. 본 연구는 이러한 문제점을 해결하기 위해 래티스 철선과 상하부 철선이 연속적으로 연결되어 비렌딜거동이 없는 순수 트러스형태를 구현함으로써 처짐성능이 우수한 새로운 형태의 데크를 고안하였다. 개발된 시스템의 구조적 거동을 평가하고자, 해석 및 성능평가 실험을 수행하였다. 처짐에 영향을 주는 요소를 중심으로 래티스 철선의 길이방향 연결형태, 간격을 해석과 실험의 주요 변수로 설정하였다. 해석과 실험은 실제 시공 시 타설되는 콘크리트 하중이 아연도 철판을 통해 철선에 작용하는 것을 고려하여 아연도 철판에 직접 등분포 하중을 가력하였다. 구조해석 및 실험을 통한 분석결과 철선 트러스데크의 길이방향 형태, 즉 래티스 철선의 길이방향 연결 형태가 구조적 거동에 영향을 주는 주요한 인자로서 작용했으며, 래티스 철선을 길이방향으로 연속적으로 연결함으로써 비렌딜거동에 의한 영향을 감소시킬 수 있었다. 또한 래티스 철선의 연결간격을 증가 시킬 경우에도, 상, 하부 철선에 큰 응력증가 없이 우수한 처짐 성능을 발현 할 수 있었다. A truss deck system that has replaced the slab form conventional method has become widely used in the construction of reinforced concrete structures as well as steel structures. The current commercial products, however, have some problems. The discontinuity between the lattice wires on the joint of the bottom wire induces vierendeel behavior, which increases the deflection of the system. In this research, a new truss deck system with continuous lattice wires on the level of the bottom wire was developed to reduce the system's vierendeel behavior and to improve its deformation capacity. To investigate the system's structural behavior, an experimental test and an analysis were performed. The main parameters of the test and analysis were the longitudinal shape and spacing of the lattices. To simulate the loading condition in the construction field, uniform construction loads were directly applied on the deck plates of the analysis model and the test specimens. The results of such analysis and test revealed that the longitudinal shape of the lattice wires is a major factor affecting the structural behavior of a steel wire truss deck. Thus, continuous lattice wires could result in decreased vierendeel behavior in the steel wire truss deck. It was also found that the truss deck system with lattices spaced longer than in the conventional products could be effectively used without increasing the member stresses.
