This study investigated fabrics, washing and cares, design, pattern, subsidiary materials, and sewing methods with a focus on the functional outers using moisture-permeable waterproof fabric as a shell; in addition, each element was analyzed for differences depending on fabric type. The characteristics of 34 outers were investigated through labels, online product introductions, visual inspection, observations from two experts with more than 30 years experience and wear tests. Moisture-permeable waterproof fabrics used for the outer were classified into two types; in addition, the shell of the high-density fabric and the 2 & 3-layer fabrics had different characteristics. Various fabrics, detailed designs, and three-dimensional patterns suitable for each part of the human body were used to improve functionality. In addition, various subsidiary materials and sewing methods were used to form an organic relationship. The same washing and cares, patterns and subsidiary materials were used regardless of fabric type; however, the fabric type influenced the detailed design and sewing. The outers with high-density fabric had a loose fit, short placket, e-banded cuffs, lock-stitch, and lock-stitch+binding. However, the outer with 2 & 3 layer fabric had a slim fit, hood width adjustment, zippered pockets, cuffs with tab, seamless adhesive sewing such as laminating, lock-stitch+ seam-sealing, and welding.

It is possible to use pallet for forwarding as chinese cabbages and radishes are general large-scale trading items at the agricultural wholesale market though, however, most of these are forwarded as it have packed in net bags or in P·E bags. Thus, it is still hard for palletizing. The type of packing the product in the net bag makes it difficult for palletizing. It is not a stable shape enough and easily collapsed for pallet loading. Because of this collapsibility, the corrugated cardboard box is being used to enhance forwarding efficiency, but the existing corrugated cardboard box could be crushed easily by moist what is from the agricultural product's property and it also could be squashed by the mass of the loaded box layers on itself. In contrary, the functional waterproof corrugated cardboard box is not collapsed through palletizing and it is efficient for product management with it's ventilation function in respond to pre-cooling effect. Furthermore, because it has various functional shapes as the open type, the partition type and so on, it is effective for maintaining freshness of the product and standardizing the distribution of agricultural product. It is well-known that it is possible to introduce this box to cargo-works of agricultural product. Consequently, the recognition of main distributors about the pallet distribution of the chinese cabbage and the radish was apprehended in this study for activating mechanization of loading and unloading. The survey was conducted to the main distributors such as the forwarder, the auction dealer and the commission merchant with Garak-dong wholesale market as the center. The appropriate packing materials and problems of the existing method for loading and unloading were derived through the survey. Especially, it was focused on analyzing the difference of recognition between the subject groups for the way of using waterproof cardboard corrugated box to deal with the difficult product for packing in normal corrugated box because of the box's absorption of moist from the agricultural product like a chinese cabbage and a radish. Total In the cases of the forwarders and the commission merchants, the net was highly responded as 45%, 74% from each groups for the best packing material for mechanization of distribution and the waterproof corrugated cardboard box was responded as 20%, 22% from each groups as much preferable than multi-stage wooden box. However, for the radish, the waterproof corrugated cardboard box was the best material as 56%, and the auction trader group supported it for 80%. So, the using the waterproof corrugated cardboard box for mechanization of distribution was negative for the chinese cabbage, but it was positive for the radish. The average was 2.42, the standard deviation was 1.24. The negative response(about 55%) was prevailing more than positive response(about 23%). It could be analyzed that even there was the positive recognition for using the waterproof corrugated cardboard box for the radish though the preference for low price of net bag in the chinese cabbage forwarding procedure. Still now, it seems that is a burden for using the waterproof corrugated cardboard box with high price. In the analysis on the recognition differences about using the waterproof corrugated cardboard box for the chinese cabbages and the radish between the forwarders and the commission merchants, generally the negative recognition was prevailing, but the forwarders(2.696) were more positive for using the waterproof corrugated cardboard box than the commission merchants(2.145).

The Floating Photovoltaic System was installed on the surface of water. There were some researches in this subject. But there was not many studies with experiment on a high waterproof Floating Photovoltaic modules. The aim of this study was to analyze the performance of the Floating Photovoltaic System. For this experiment, a high waterproof Floating Photovoltaic modules were designed and applied to the module capacity of 10 kW Tracking-Type structure. The experiment results indicated the performance of the daily production is 51.6 kW; the production capacity of Floating Photovoltaic System is expected to be 23% higher than that of the ground-mounted photovoltaic system.

A multi-component force sensor has been developed to measure force and moment components in high-speed flow media for submerged models. The size of the test model is determined based on the Reynolds number of the model at the test speed and expected blockage effect. A two-component force sensor unit has been created by assembling pairs of column elements arranged symmetrically under an eccentric load. The six-component force sensor is constructed with symmetric arrangements of two-component force sensor units in a rectangular plane. The signals generated from the strain gauges attached to the surface of the elements can be converted into force signals. The performance of the waterproof six-component force sensor has been evaluated through calibration. A simplified interference decomposition procedure has been introduced to increase the accuracy of measurement.

Seat waterproofing materials applied to the roof of a building concrete structure inevitably produce joints and are applied with opposite dam joints or overlapping joints depending on the waterproof material applied to the top of the sheet. In this case, the joint performance is determined by the material at the top, rather than by the superimposed joint. In order to solve this problem, various reinforcements have been used to apply to the connecting parts of the opposite dam, but the problem of attachment between different materials or the lack of reinforcement of the joint tape has not been solved. Therefore, for the purpose of securing tensile performance to the joints, this study is used as a reinforcement for the joints of PP materials with high tensile performance and as a reinforcement for nylon materials.

기존의 다층으로 구성되어 시공성이 낮은 옥상녹화 공법의 개선을 위해 개발한 방수 방근 시트 일체화 옥상녹화박스 유닛공법의 일체화를 위해 사용하는 전자기 유도가열방식의 금속 고정구와 콘 형상 고정구의 부착성능을 평가하기 위해 엔지니어링 PE, TPO, PVC 시트 등 3종류의 시트에 가열온도에 따른 부착성능 및 동일한 시험체로 냉열반복 후 부착성능을 측정하였다, 그 결과는 엔지니어링 PE시트에 부착한 고정구의 부착성능이 가장 우수하게 나타났으며, 금속고정구는 가열온도가 올라갈수록, 콘 형상 고정구는 가열온도가 낮을수록 우수한 부착성능을 보여주었고, 냉열 반복 후 부착시험 결과는 상온 부착시험 결과와 동일하게 나타났다. 기존의 양면 부틸테이프 고정방식의 콘 형상 고정구는 낮은 부착하중과 냉열반복에 의한 뚜렷한 성능저하가 발생하는데 비하여 전자기 유도가열방식의 고정구는 우수한 성능을 유지하였다.

지하구조물에 있어서 누수사고의 빈번한 발생 및 상습화 경향에도 불구하고 현재 국내에서 사용되고 있는 누수보수방법은 누수유형에 관계없이 일괄적으로 동일한 처리방식으로 보수하는 상황으로서 지하구조물 누수에 대하여 누수 유형별로 보수방법을 달리하는 적극적인 해결방안의 모색이 필요하다. 따라서, 본 연구에서는 지하구조물의 누수보수에 있어서 방수 그라우트재의 공학적 특성을 파악하고 현장상황에 적합한 방수그라우팅 기법을 수립하여 누수유형별로 적용한 사례를 중심으로 적용성을 고찰하였다. 방수그라우팅 적용사례를 분석한 결과 지하구조물의 누수방지를 위하여 누수상황 및 누수유형에 따라 주입재의 배합비를 적절히 변화시켜 주입재와 현장상황에 적합한 방수그라우팅 기법을 병행 적용하는 것이 확실한 방수효과를 얻을 수 있으며, 주입목표구간에 대해 단계적으로 수회로 나누어 순차적인 그라우팅과 가능한 한 저압, 소량, 장시간에 걸쳐 주입하는 것이 방수그라우팅 효과를 증대시킬 수 있는 것으로 판단된다. 또한, 현장 적용결과로부터 기존 방수이론의 영향요소에 추가하여 물시멘트비, 주입재의 입경, 주입시간 및 주입량, 혼화재 사용여부, 주입차수 등에 대한 다양한 영향요소의 검토가 필요한 것으로 판단된다.
