In this paper, methods to analyze wire sweep during the semiconductor chip encapsulation have been studied. The wire sweep analysis is used to analyze the deformation of bonding wires that connect the chip to the leadframe during encapsulation. The analysis is done using either analytical solutions or numerical simulation. The analytical solution is used for rough but fast calculation of wire sweep. The results from the numerical simulation are closest to the experimental results.

For the purpose of domestic production of ultrasonic transducer, experiments on material selection for backing and matching layer, and electrical impedance matching between transducer and equipment were performed. The characteristics of manufactured transducers with experimental results were analyzed and compared with foreign products. Through the evaluation of the transducers manufactured and the comparision with foreign products, it is confirmed that the transducers manufactured show the good performance characteristics and efficiency.

We establish a necessary and sufficient condition for a heptagonal knot to be figure-8 knot. The condition is described by a set of Radon partitions formed by vertices of the heptagon. In addition we relate this result to the number of nontrivial heptagonal knots in linear embeddings of the complete graph $K_7$ into $\mathbb{R}^3$.

Concerning to Taeku city subway construction project(1-4 site), the original design was adapted NATM Tunnel method to the 8 meter thickness of overburden. Surveyor checked sity and design material and finally decided to change into Open Cut method because overburden is not only below 1 1/2 times thickness of comparate Tunnel width but there is no traffic conjunction in job site.

퍼스널 클라우드는 클라우드 컴퓨팅에 대한 관심이 높아지고 활발한 연구가 진행되면서 개인 사용자들의 클라우드 서비스에 대한 욕구를 충족시키기 위한 서비스이다. 국내외에서 IT기업을 중심으로 퍼스널 클라우드 서비스를 제공하고 있다. 하지만 표준기술 없이 개발된 퍼스널 클라우드 서비스는 각 클라우드 서비스 제공자에 종속되어 호환성이 낮으며, 서비스 및 개인정보에 대한 보안 정책도 명확하지 않고 개인화 서비스를 제공하기 위한 보안 가이드라인도 부족하다. 따라서 본 논문에서는 퍼스널 클라우드 서비스에 대한 정의 및 요구사항과 퍼스널 클라우드 보안 기술에 대한 보안 표준화를 분석한다.

The Problem of vibration Inflence to housing Construction fields has arised at the begining of 1970, at That time I used Lion(VM -l2B) which recorded only dB Demension. On the 1980's I have been used lnstantel made blastemate(DS-477), modern Instrument for measuring speed, Acc, frequency and placement. but The most of Jobsite used Lion I Carried out the empirical equation of conversion dB to cm /sec as follows. Single free face : dB = 140PPV + 30 double free face : dB = 143PPV + 20 Above equation Could apply on Rock type 3(soft rock)

In the pilling works in the city, it is tend to transfered to the non-vibration pilling works. This drop-hammer pilling executed with in 2 meters distance to neighbour building structure. in the rainy season. According to imperical formula which tested in similar site, Vibration damaged area is within 14 meters radius from drop-hammer pilling site. The loratories Data of Dae Woo of Korea hausing Authority are refered to above poject.

The design and manufacture of injection-molded parts with desired properties is a costly process dominated by empiricism, Including the repeated modification of actual tooling. The objective of this study is to obtain the good design of injection-molded polymeric parts using axiomatic design approach.
