본 연구는 All-In-One system의 적용 시간과 도포횟수에 따라 유치 상아질과 복합레진의 접착 강도와 혼성층에 어떤 영향을 미치는지를 규명하고자 Single bonding agent(Scotchbond Multi-Purpose Plus, 3M, USA)와 All-In-One system(Prompt-L pop, 3M ESPE, USA)를 사용하였고 수복용 레진으로 복합레진(Z-250, 3M, USA)를 사용한 결과 다음과 같은 결과를 얻을 수 있었다. 1. 전단 결합 강도는 Single bonding agent를 적용한 경우 All-In-One system을 적용한 군보다 유의하게 높게 나타났다(P<0.05). 2. Prompt L-pop을 2회, 3회 적용한 경우에 전단 결합 강도는 1회 적용한 군보다 유의하게 높게 나타났으며(P<0.05), 혼성층의 두께는 1회 적용군보다 2회, 3회 적용한 군에서 증가하였다. 3. Prompt L-pop을 15초 적용한 경우에 전단 결합 강도는 7초 적용한 군보다 유의하게 높게 나타났으며(P<0.05), 30초 적용군과는 차이가 없었다. 혼성층의 두께는 7초 적용군이 가장 얇고, 15초군과 30초군에서는 차이가 없었다. 4. Single bonding agent를 이용한 경우 두터운 $2-4{\mu}m$의 혼성층이 관찰된 반면, All-In-One bonding system(Prompt L-pop, 3M ESPE, USA)에서는 비교적 얇은 혼성층($1-2{\mu}m$)이 형성되었다.

The purpose of the paper is to analyze situations and its prospect of Single Window System for custom's one-stop service in Japan and to suggest effective application was to improve of in Korea's Customs systems. In response to the growing demand for lower trading costs and shorter and more predictable lead times with the advancement of the international trade supply chain, the Single Window System for import/export and port-related procedures was launched on 23 July 2003 in Japan. The concept of the Single Window System is to establish a comprehensive computer interface system that enables users to complete all import/export and port-related procedures required under different laws and regulations in a single input and single transmission. To realize the concept, the data elements and submission times of the various systems were harmonized, and manual procedures, such as quarantine and immigration, were computerized. Then, all the necessary systems, such as NACCS, Port EDI System, and Crew Landing Permit Support System, were interconnected as a Single Window System. Close cooperation among other governmental organizations and the private sector was a key factor in the successful development and smooth utilization of the System so that it fully met all parties' needs. It is anticipated that operating costs will be greatly reduced and trade facilitation will be enhanced as a result of the simplification of procedures. Korea Customs advocates the Single Window System as a best practice at ASEAN and WCO to contribute to the development of regional and international capacity building.

The purpose of this study was to elucidate the effect of benzalkonium chloride on tensile bond strength of BPDM/HEMA dentin bonding. One hundred sixty dentin specimens from freshly extracted bovine mandibular incisors were used, and 0, 0.02, 0.1 or 0.5% benzalkonium chloride solution was applied to the dentin specimen with/after phosphoric acid. 32% phosphoric acid was used when the specimens were bonded with One-Step$^{TM}$, a BPDM/HEMA system and 10% was used when bonded with All-Bond$^{(R)}$ 2, a NTG-GMA/BPDM system. Aelitefil$^{TM}$ composite resin was bonded to the pretreated dentin specimen with the use of All-Bond$^{(R)}$ 2 or One-Step$^{TM}$ dentin bonding agent. After the bonded specimens were stored in $37^{\circ}C$ distilled water for 24 hours, tensile bond strength was measured. The fractured dentin specimens were examined under the scanning electron microscope. The results were as follows : Benzalkonium chloride application after acid-treatment resulted in decrease of dentin bond strength of One-Step$^{TM}$, a BPDM/HEMA system (p>0.05). Benzalkonium chloride application did not exert any influence on dentin bond strength of All-Bond$^{(R)}$ 2, a NTG-GMA/BPDM system (p>0.05). There was no relationship between the concentration or application method of benzalkonium chloride and the dentin bond strength of One-Step$^{TM}$ or All-Bon$^{(R)}$ 2 (p<0.05). On SEM examination of the fractured dentin-resin interface, while mixed failure was prominent in dentin bonding with One-Step$^{TM}$, adhesive and mixed failures were seen together in dentin bonding with All-Bond$^{(R)}$ 2 regardless of the concentration and application method of benzalkonium chloride.

We studied on the development of clothing pressure measurement system for wear comfort of foundations(girdle, brassiere, all-in-one). Measurements of clothing pressure were made on subjects wearing girdles, brassieres, all-in-ones of several type(material, size) using by CPMS(clothing pressure measurement system: Tech-Storm. Co). Wearing experiments have been carried out using nine women in the twenties and six women in the forties. The results obtained are as follows: 1. The clothing pressure applied by girdle was higher in the hard type than the soft type by $5-10gf/cm^2$, also recorded a high clothing pressure at points of waist band line and thigh lateral. 2. Clothing pressure of brassiere with wire was high at the point of underbust line and shoulder strap. Pressure for 40s showed higher than 20s by $6-7gf/cm^2$. 3. The pressures of abdominal part applied by both of girdle and all-in-one were much greater than those of girdle or all-in-one. 4. We demonstrated the adaptability and conformity of the CPMS by inquiring into the clothing pressure of various foundations.

In this pattern recognition on the large volumes of remote sensing satellite images, the inference time is much increased. In the case of the remote sensing data [5] having 4 wavebands, the 778 training patterns are learned. Each land cover pattern is classified by using 159, 900 patterns including the trained patterns. For the fuzzy classification, the 778 fuzzy rules are generated. Each fuzzy rule has 4 fuzzy variables in the condition part. Therefore, high performance parallel fuzzy inference system is needed. In this paper, we propose a novel parallel fuzzy inference system on T3E parallel computer. In this, fuzzy rules are distributed and executed simultaneously. The ONE_To_ALL algorithm is used to broadcast the fuzzy input to the all nodes. The results of the MIN/MAX operations are transferred to the output processor by the ALL_TO_ONE algorithm. By parallel processing of the fuzzy rules, the parallel fuzzy inference algorithm extracts match parallelism and achieves a good speed factor. This system can be used in a large expert system that ha many inference variables in the condition and the consequent part.

Recently, researches on all-electric subsea system have been in progress. This paper describes a subsea tree using a lot of electrical signal and subsea control system. The way of subsea control is classified as all-electric systems or electro hydraulic systems. One of that has more merits in terms of cost, weight, power consumption, etc. because it uses electric signal instead of hydraulic signal. This paper describes the difference of each system's power consumption and simulation. As the result, if each system applies the same number of sensors, actuators, etc. The power consumption of all-electric system's load is less than at least 400kWh/day compared to the electro hydraulic system load.

Application of CAD/CAM is changing the way partial or full veneer all ceramic restoration is made. CAD/CAM systems, which were used mainly in other industries, have been developed and introduced for the dental purposes recently. It produced a flood of information on the CAD/CAM systems. It also influenced the development of restorative materials and all ceramic is substituting the traditional restorative materials of gold, composite resin and metal. Price increase of gold and other raw materials made the all ceramic more appealing. The introduction of a CEREC 3D system was innovative in several ways. Image of the prepared tooth is captured by camera and impression taking is unnecessary. Restoration can be delivered to the patient on one appointment and it will satisfy the demand of busy patients. One-day treatment with direct CAD/CAM system saves time compared to indirect CAD/CAM system. More superior restoration can be produced if lab work such as the adaptability check and shade selection is cooperated with lab technician. Short working time and comparably superior shade compatibility of color block was close to ideal. In the future, restorations with better quality can be fabricated in less time to busy patients thanks to the development of CAD/CAM system and dental materials.
