This study aims at providing the fundamental data on the field of cosmetics by comparing heavy metal concentration in terms of domestic/foreign products, items, companies and colors. This study has determined the concentration of chromium, lead, mangagnese, nickel, copper and vanadium in cosmetics such as moisturizer, concealer, foundation (Ivory-yellow), compact powder (Ivory-yellow), lip colo. (Red, brown), eye shadow (Red, brwon and dark green) and eye liner (Black) manufactured by five domestic cosmetic companies and five foreign cosmetic companies on the market. The samples have been collected in cosmetic stores in Pusan from Dec. lst 1996 to Jan. 3lst 1997. The results are as follows : 1. The heavy metal concentration in cosmetics was $2.420{\mu}g/g$ for chromium, $0.82{\mu}g/g$ for lead, $4.49{\mu}g/g$ for manganese, $1.69{\mu}g/g$for nickel, $0.53{\mu}g/g$ for copper, and $51{\mu}g/g$ for vanadium, respectively. 2. Lead and vanadium concentration were significantly higher in domestic cosmetics than foreign cosmetics(p<0.05). 3. The mean(GM) concentrations of heavy metal were different significantly (p<0.01) when classified with cosmetic items. The highest means shown at eye shadow in $Cr(14.96{\mu}g/g),\;Cu(1.32{\mu}g/g),\;V(1.28{\mu}g/g),\;and\;Ni(8.30{\mu}g/g)$, compact powder in $Pb(2.50{\mu}g/g)$, eye liner in $Mn(90.62{\mu}g/g)$. 4. The mean(GM) concentrations of heavy metal were different significantly (p<0.01) among colored cosmetics. The highest mean concentration of Cr, Ni, Cu and V were dark green-colored cosmetics, that of Mn was black-colored cosmetics, and that of Pb was ivory yellow- colored cosmetics.

This study aims to contribute to development of sanitary pad meeting customers' requirements by examining types, sorts, sizes and specifications of cloth sanitary pads currently sold in the market, and the results are as follows. First, with respect to materials of inside cloth of cloth sanitary pads, in most cases, 100% cotton knit was used as materials of the inside cloth and the pads were finished with knit cotton(including organic cotton) and woven cotton bias. Second, for the structures of the cloth sanitary pads, the Jacquard knits in the shape of beehive or waffle are mostly used. Third, the sizes of cloth sanitary pads were classified with 7 sorts were discovered that can be divided into liner, small-size, medium-size, large-size, overnight, extra overnight, accounting for the most percentage among cloth sanitary pads. Fourth, 11 sorts among cloth sanitary pads whose front and back shapes are the same were discovered, accounting for the most percentage. Fifth, cloth sanitary pads can be largely classified into a wing type, all-in-one type and insertion type, which includes subsidiary absorption layer. 9 sorts were wing types and all-in-one types, accounting for the most and percentage. Compared with the scope of the market for women's articles, there is no relevant study, so this study is expected to provide basic materials for women's articles and contribute to development of environment-friendly products as an alternative to a disposable sanitary pad which not only causes environment pollution but also has bad effects on women's health.

Purpose - To meet the needs of various customers in an uncertain market environment, many companies use product modularization strategies. Modularization of a product means that one product consists of several components and that the type of product can be changed according to the combination of components. The greatest feature of modularity is that changes in one component do not significantly affect the physical changes in the other component to which they are connected. Modularization of products is recognized as a very important strategy to reflect increasingly complicated customer requirements to products and respond to the needs of various markets. Many studies have been made in connection with the concept of mass customer satisfaction. There are many prior studies that modularization of such products positively affects the operational performance (manufacturing cost, fast delivery, etc.) and innovation of the product. However, excessive modularization has been found to have a negative effect on this performance. However, there are very few studies on the nonlinear relationship between product modularization and customer satisfaction. Supplementing these academically insufficient parts is very necessary when considering the current market environment. Research design, data, and methodology - In order to make up for the shortcomings of academic research in Korea, this study collects data through questionnaires in electronic, auto, and defense industry. This is because these industries are using modularity of products. based on lots of previous studies and information overload theory, we made two hypothesis and verify with empirical analysis. All 108 data were used. We used the R program and SPSS program for statistical verification. Results - As a result of the study, modularization of products showed positive relationship with customer satisfaction to a certain level. However, it has been found that when the modularization is over and beyond a certain level, there is a negative relationship with customer satisfaction. Conclusions - Excessive modularization of products can have a negative impact on customer satisfaction. This result can be understood as a result of human limited rationality due to information overload. Therefore, it is important for companies to apply appropriate modularity to product design.

본 연구는 부산항과 인천항간 컨테이너 연안운송이 중단된 배경을 비용구조와 수입 배분의 특성, 시장에서 기업의 행동상 제약으로 구분하여 살펴보았다. 이를 위해 연안운송의 국내물류체계와 연관된 선박 운영비용의 구조를 고찰하고 비용함수를 추정하였다. 또한 연안선사내 운영수입의 배분비율을 살펴보았으며, 144TEU급과 215TEU 급 선박의 평균수입을 산정하였다. 경제적 제약 측면에서는 기업의 이윤 극대화 혹은 손실 최소화라는 목표를 전제로, 연안운송의 중단 원인을 찾으려 노력하였다. 연구 결과, 연안운송은 운영비용 측면에서 최대적재능력에 가까운 적재율을 실현하고 대형선박을 투입할 경우 규모의 경제를 실현할 수 있었다. 운영수입에서는 트럭운송시장의 영향, 복잡한 물류체계에 따른 낮은 평균수입으로 적자가 누적될 가능성이 있었다. 경제적으로는 평균수입이 평균비용보다 낮아, 연안선사가 서비스를 중단하였던 것으로 판단되었다. 따라서 전용선박에 의한 연안운송이 지속되려면 정부 등의 보조금 지원이 필요하다고 판단된다.

Indiscriminate disposal of waste and citation of open dumpsites are some of the key factors affecting the various soil geotechnical properties. Atterberg limit and consolidation tests were conducted to determine the effects of two open waste dumpsites (Uselu Market and New Benin) on geotechnical properties of their underlying soils. Soil sample collected from Uselu Market dumpsite in Benin City metropolis showed slightly lower hydraulic conductivity (K) of $1.0{\times}10^{-6}$ with plasticity index of 18.53% compared to sample collected 1.6 m from the same dumpsite which had high K value of $2.42{\times}10^{-3}$ with plasticity index of 6.9%. Soil sample collected from New Benin dumpsite in Benin City metropolis showed slightly lower K of $1.45{\times}10^{-6}$ with plasticity index of 13.8% than sample collected 1.6 m from the same dumpsite which had high K value of $2.14{\times}10^{-2}$ with plasticity index of 6.0%. X-ray florescent analyser (X-MET 7000) and direct soil pH meter were used to determine the composition of the aforementioned soil samples. The result of samples collected from both dumpsites indicated a low hydraulic conductivity compared to samples collected 1.6 m from both dumpsites. Also, the chemical composition and pH of both dumpsite underlying soils indicated high level of soil contaminants with pH of 3.3 and 3.5 which is very acidic unlike pH of other samples which were in the neutral range (6.8-7.1). Hence, a liner is recommended for all dumpsites or engineered landfill systems to mitigate against the challenges associated with open waste dumping system in the environment.

There are three basic modes of operation of ships: liner, tramp and industrial operations. Industrial operations, where the owner of the cargo, i.e. the industrial carrier controls the ships, abound in the shipment of bulk commodities, such as oil, chemicals and ores. Industrial carriers strive to minimize the shipping cost of their cargoes. This paper is concerned with the operational optimization problem of a fleet owned by major international oil company. The major oil company is a holding corporation for a group of oil producing, transporting, refining, and marketing companies located in various countries throughout the world. The operational optimization problem of the fleet is divided into two-phases. The front end corresponds to the optimization of transporting crude oil, product mix, and the distribution of product oil to meet market demand. The back end tackles the operational optimization problem of the fleet to meet the transportation demand derived from the front end. A case study is carried out with the H major oil company problem composed by reflecting the practices of an international major oil company. The results are summarized and examined in the point of optimization for the total operation of the H major oil company and the operational optimization problem of the fleet. The paper concludes with the remark that the results of the study might be useful and applicable in practices of these related decision problems.

Shipping industry continues to face dramatic changes in its environment ranging from development in containerization, computerization and telecommunications to the emergence of global marketplace. Perhaps the most significant trend - representing both a threat and opportunity - is the increasingly competitive nature of shipping service market. In order for the shipping companies to cope with those improvements and challenges, they should analyze and clarify customer's DM(decision making) process for the purchase of container shipping service. The major research findings from the study were found as follows; 1) The degree of shipper's involvement in purchasing shipping services was found to be a discriminating variable affecting the information sources consisting of personal and non-personal information sources. 2) The positive relationship was found between the experiences on shipping services and non-personal information sources. 3) It was observed that as people had more experience searching for information, the more in depth their searches became. 4) There existed a positive relationship between knowledges on shipping services and information search. 5) According to the SEM analysis, the shipper's information search on shipping services was also found to have a great influence on the shipper's purchasing behavior. The shipper's search was resulted in positive customer satisfaction.

This study was conducted because the global economic downturn caused by COVID-19 caused a surge in logistics costs and it was no longer possible to predict logistics costs using existing methods. For this study, we made the assumption that economic indicators affect logistics cost. Chapter 2 examines the current status of the liner market and factors affecting logistics costs. Based on this, Chapter 3 collects independent and dependent variables to determine the analysis model. As the independent variable, economic indicators of major countries constituting the SCFI were selected, and the dependent variables were the SCFI Europe Index and the SCFI USA Index. In Chapter 4, a panel analysis was conducted based on this, and it was confirmed that major economic indicators had a negative (-) effect on SCFI. This is contrary to the existing research results, which can be attributed to the special situation caused by COVID-19 and the imbalance of demand and supply by region. The results of this study are meaningful in that they can predict long-term logistics cost volatility without analyzing supply and demand, and can be applied to other studies as well.

2017년 초 한진해운의 파산에 따라 세계 컨테이너 운송시장에서 차지하는 국적선의 비중 및 역할이 현저하게 줄어들었다. 이에 우리나라의 수출입 기업 뿐만아니라 항만들도 위기를 맞게 되었다. 더구나 미국 트럼프 대통령이 촉발한 관세 및 무역전쟁은 북미 향발 화물의 증가에 부정적인 영향을 초래하고 있다. 반대로 초대형 선사들인 머스크나 CMA CGM과 자국 내 컨테이너 선사간 인수 합병한 중국 및 일본 컨테이너 선사들은 국내 유일의 세계 10대 국적 컨테이너 선사이던 한진해운이 파산함에 따라 선복 공급 감소의 반사이익을 얻고 있다. 수출입화물의 무역거래에서 외국적선사의 권력이 더욱 커지고 있다. 이에 따라 부산 및 광양 등 국내 항만은 해외선사와의 협상력 약화가 초래 되어 선사 유치가 더욱 어려워질 수 있다. 본 연구는 이러한 상황에서 사회연결망의 위상학적 분석과 LSCI 및 CPCI의 경제학적 분석능력을 결합하여 2007년과 2017년의 전 세계 컨테이너 운송네트워크를 비교하였다. 연구결과 항만의 역할을 파악할 수 있으며, CPCI가 중심성지수 및 물동량자료와 높은 상관관계를 갖기 때문에 별도의 중심성 분석 없이도 필요한 중심성지수가 갖는 의미를 활용할 수 있다. 본 연구결과를 우리나라 선사들의 기항 전략과 우리항만의 제휴항만전략 및 발전전략에 활용할 수 있을 것이다.
