The purpose of this study was to examine physiological changes of the body according to various weight loads and the holding during carrying object. The experiments were conducted with utilizing physiological analyses for five male and five female adults as subjects. The results were as followed. 1. Any significant difference was not shown in heart rate, ventilation and amount of oxygen uptake of male subjects in the case of no load and 5kg. And also no significant difference was shown in expiratory exchange ratio of male subjects of no load, 5kg and 10kg, but in other measure items and other stages of weight was shown. 2. Significant differences were shown in heart rate, ventilation, defluxion of carbon dioxide, oxygen uptake per body weights, respiratory exchange rate, respiration rate and all other measure items of female subjects in all stages of load. 3. In the MMH job, there was no influence on male subjects up to 5kg loads, but there was an significant difference in male subjects in load walking from 5kg. It shows that even in 5kg weight MMH work, female subject's expiratory function was influenced. 4. 10kg load was the limit weight of female subjects and 15kg was of male subjects when they walked on treadmills with 4km/h velocity for 3 minutes, holding loads in the right and vertical types.

The Application of Time-Resolved Laser Induced Fluorescence Spectroscopy in the Complexation Studies of Eu(III) and Cm(III) with Humic Substances

The application of time-resolved laser induced fluorescence spectroscopy (TRLIF) to the complexation studies of Eu(III) and Cm(III) with humic substances is described. Using this method, three different spectroscopic characteristics(excitation spectra, emission spectra, and lifetimes) of these aquo ions and their complexes can be directly measured. By observing shifts in the wavelength and changes in the lifetime and intensities of the fluorescence emission, the information on the complexation behavior of humic substances with these trivalent metal cations in an aqueous solution, as well as energy transfer mechanisms, can be obtained. In addition, this method allows precise spectroscopic quantification of the complexation processes at very low concentrations of both components.

During the past 50 years, the maternal mortality ratio has decreased dramatically. The leading causes of maternal deaths were pulmonary embolism, the complications of the pregnancy-induced hypertension, hemorrhage, the complications of the ectopic pregnan

Design and Construction of the Cylindrical Slit Type Shore Structures

Joong Woo Lee,Ki-Dae Nam,Sang-Gill Park,Sug-Moon Kim,Seok-Jin Kang 한국항해항만학회 2009 한국항해항만학회지 Vol.33 No.9

In this study, a series of laboratory experiments were carried out to investigate the weak reflection of regular and random water waves over a train of protruded permeable shore structures. A cylindrical slit type breakwater and the alternatives are employed and compared for reflecting and transmitting capabilities of incident waves including wave forces. A series of random waves were generated by using the Bretschneider-Mitsuyasu frequency and directional spectrum. Measured spectrum of irregular waves without breakwaters is verified by comparing with those of the input waves generated. Weak reflection is occurred at the breakwater center of the peak frequency. If the row of breakwaters is fixed at three layers and the relative height of breakwater is fixed at 0.6, around 45% of incident wave energy is reflected to offshore. It is also found that the transmission of directional random waves increases as the maximum frequency parameter increases. A very good agreement is observed. Reflection coefficients of permeable submerged breakwaters are less than those of impermeable breakwaters. The upside-down L shape is recommended for a small fishery harbor mooring in terms of reflecting capability and of practical application. The final design was applied to the wharf of a small beach of Seolly, near Namhae at the southeast coast of Korea.

상품진열이 중간상의 상품선택에 미치는 영향

안길상(Gill Sang Ahn),윤태중(Tae Joong Yoon) 한국유통학회 2005 流通硏究 Vol.10 No.1

다원적 회원조직으로 운영되는 다단계판매회사의 주고객은 다단계판매회사로부터 구입한 상품을 다른 회원에게 재판매하는 독립적인 사업주체인 중간상(IBO)인데 이들은 일반 중간상들과는 달리 경쟁제품이 없는 자사 매장에서 자사 상품만을 배타적으로 구입해야 하고 취급상품의 종류, 가격, 기능 등에 대해서 상세한 정보를 가지고 있다는 특징이 있다. 일종의 도매상 기능을 수행하는 이들을 대상으로 상품을 판매하는 다단계판매회사가 그들 상품의 진열방법 예컨대 진열량, 진열높이, 진열위치, 관련상품진열 등을 달리함에 따라 매출액에 변화를 줄 수 있는지에 대한 연구나 관심은 거의 없었다. 본 연구는 매장규모가 다른 대규모, 중간규모, 소규모 점포 각각에 대해 진열방법에 차이를 두었을 때 다단계판매회사의 매출액에 어떤 영향을 미치는지 실험을 통해 분석하였다. 그 결과 첫째, 점포규모와 상품진열방식 두 변수의 상호작용에 의한 매출 변화를 살펴본 결과 매출액에 변화가 없었다. 둘째, 이에 따라 주효과만을 분석한 결과 점포규모는 매출에 영향을 주고 셋째, 상품진열방식 중 진열량, 진열높이, 진열위치는 매출에 영향을 주지 않지만 관련상품진열은 매출에 유의한 영향을 주는 것으로 파악되었다. 넷째, 상품진열만을 독립변수로 하여 추가 분석을 실시한 결과 대규모 매장의 경우 진열량을 제외한 진열위치와 진열높이, 관련상품진열 모두가 매출에 유의한 영향을 주는 것으로 나타났다. After 1990's, many multi-level marketing companies have been introduced in Korea. These MLM companies operate their stores as same way as general retailing stores. The major characteristics of these MLM companys' store is that their main customers are distributors who sell the purchased merchandise to another customers. Many studies about merchandise display in general retailing stores were reported. But, there was less research about merchandise display in these special type stores such as MLM companys' stores. This paper investigates the effects of merchandise display on distributor's merchandise selection in channel flow of multi-level marketing company. For this purpose, we formulated four hypotheses about display variance in quantity, height, location, and related merchandise to analyze the effect of merchandise display methods in MLM companys' stores. The experiment had been proceeded in three stores in a MLM company for 6 weeks and the sales data were collected by POS. The methods to analyze the data were used ANOVA and T-test. Findings of this study are as follows; First, there was no effect to store sale by the interaction effect between merchandise display method and scale of store. Second, scale of store affected considerably the volume of sales of each store according to main effect analysis. Third, display variance in quantity, height, and location did not affect store sale. In the related merchandise display, however, sale in all store was increased. Fourth, in additional analysis considering merchandise display only, display variance in both height and location affected their sale in large scale store. Based on the above results, we may predict merchandise display can affect sale in MLM companys' store as well as general retailing stores. Therefore if MLM company has large scale store, it should consider merchandise display methods in its stores.
