This paper addresses some issues on the Northern Nigerian traditional garments and caps. We observed that most of the Northern Nigerian garments and caps, particularly those of the Kanuri people, have their origin in the culture and traditions of the people. In very significant ways, the garments and the caps depict the belief systems, political metaphysics, and the general consciousness of the people including their creative impulses. But as more and more people move from rural areas to the cities, travel abroad and as more and more cultures intermingle, inevitable changes catch up with the culture and tradition of the people. We observed that it is hard to find in the Northern Nigeria scene, particularly among the Kanuri people, clothes that have assumed new nomenclature other than garments and caps. We realized that, the culture and tradition of the Kanuri people wearing longer, voluminous and roomy garments preferably with cap have witnessed changes due to the blend with foreign culture. This and many other issues are discussed in this paper. The purpose of this research is to show that inspite of the Kanuri people's strong adherence to their beliefs and culture which hardly encourage any changes, the use of their traditional garments and caps have exhibited the flexibility of their beliefs, culture and traditions. The use of the garments and caps discussed in this paper are those observed among the Kanuri people of Northern Nigeria.

Investigation of the stability of arch dam abutments is one of the most important aspects in the analysis of this type of dams. To this end, the Bakhtiari dam, a doubly curved arch dam having six wedges at each of its abutments, is selected. The seismic safety of dam abutments is studied through time history analysis using the design-based earthquake (DBE) and maximum credible earthquake (MCE) hazard levels. Londe limit equilibrium method is used to calculate the stability of wedges in abutments. The thrust forces are obtained using ABAQUS, and stability of wedges is calculated using the code written within MATLAB. Effects of foundation flexibility, grout curtain performance, vertical component of earthquake, nonlinear behavior of materials, and geometrical nonlinearity on the safety factor of the abutments are scrutinized. The results show that the grout curtain performance is the main affecting factor on the stability of the abutments, while nonlinear behavior of the materials is the least affecting factor amongst others. Also, it is resulted that increasing number of the contraction joints can improve the seismic stability of dam. A cap is observed on the number of joints, above which the safety factor does not change incredibly.

The purpose of this study is to develop comfortable patient gown for spinal surgery patients. The results of the survey confirmed inconveniences and problems with the current gown, and a new gown style was recommended. The recommended changes addressed design, pattern, and materials. The final experimental design for the top of the new patient gown is a wrap style that moves the center opening of the gown to the side and enables patients to control the length of the sleeves by attaching two snaps. The cutting line is aligned with the back brace location, and the issue of repeated bunching of the gown material by the brace was solved by substituting 100% knitted structure fiber. The sleeve length can be adjusted with snaps on the sleeve cap and hem. When lifting up the gown for treatment on specific areas of the body, doctors open the edge of the right side of the gown in order to lift up the top. The bottom of the new patient gown was made from 100% cotton knitted structure fiber, and it enables patients to control the length of pants by attaching two snaps on the side. The results of an on-site dressing suitability evaluation and a flexibility evaluation with respect to dressing/undressing indicated that the new patient gown was much better received than the existing gowns (A and B). Our hypothesis regarding new patient gowns was supported in both the fit and design categories.

기업의 의사결정은 실물옵션의 특성을 갖는 경우가 빈번하다. 이러한 옵션의 가치를 산정하는 일은 쉽지 않기 때문에 일방이 유리한, 즉 불평등한 계약이 맺어지는 경우 또한 흔하다. 기업의 합리적인 의사결정을 도모하기 위해서는 의사결정에 내장된 실물옵션의 성격을 정확하게 규명하고, 그 가치를 경제적으로 산정하는 방안이 체계화되어야 한다. 이에 본 연구는 건설 기업의 태양전지 구매 사례를 바탕으로 이 계약에 내장된 옵션을 분석하기 위한 프레임을 제시하였다. 또한, 이 상황에서 건설 기업이 취할 수 있는 두 가지 전략적 의사결정을 도출하고 이 전략이 갖는 가치 및 그 의미를 고찰하고자 하였다. 먼저 가격 상한의 성격을 규명하고 그 가치를 산정하였다. 그 다음으로 의사결정을 연기하는 전략을 취함으로써 얻을 수 있는 가치도 평가하였다

지금까지 한강수계에서 임의적으로 시행되던 수질오염총량관리제도가 의무적 시행으로 전환될 예정이다. 본 연구에서는 갭분석과 계층화분석 등의 객관적인 접근을 통해 이러한 의무적 시행을 지원할 수 있는 조사 연구 방향 및 우선순위를 제시하였다. 갭분석 결과 아직까지 우리나라의 총량관리는 새로운 제도를 정착시키기 위한 규제에 초점을 두는 제도시행의 초기적 특성을 보이고 있어, 향후에는 배출권거래의 도입, 배출허가시스템의 개선 등 시행의 유연성 및 실효성을 제고하는 제도개선 분야에 대한 조사 연구가 필요한 것으로 나타났다. 계층화분석 결과를 보면 특정분야보다는 제도개선 및 과학적 불확실성 해소를 위해 전 분야의 조사 연구가 병행될 필요가 있는 것으로 나타나 아직 제도의 시행이 안정화 단계에 이르고 있지 못함을 반영하고 있다. 세부분야 별 조사 연구의 필요성은 목표수질 설정의 타당성 확보가 가장 큰 것으로, 기술적 측면에서는 부하량 및 수질예측 모델의 신뢰성 제고 및 획기적인 부하량 및 삭감방안의 개발이 강조되어야 할 것으로 나타났다.
