Purpose: The aim of the current study is to report on the clinical and radiographic results after calcaneo-stop procedure in Korean children with symptomatic flexible flatfoot. Materials and Methods: Twenty-two children suffering pain along the medial aspect of midfoot with flexible flatfoot whose symptoms did not improve with conservative measures and therefore underwent calcaneo-stop procedure were identified retrospectively. Clinically, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale and visual analogue scale (VAS) were evaluated. Radiographically, standing anteroposterior and lateral radiographs of the foot and Saltzman's alignment views were taken and talonavicular coverage angle, lateral talo-first metatarsal angle, and hindfoot alignment angles were measured and analyzed. Results: Clinically, AOFAS ankle-hindfoot scale improved from $70.3{\pm}5.6$ to $97.3{\pm}2.5$ and VAS improved from $6.4{\pm}1.6$ to $0.2{\pm}0.4$. Radiographically, talonavicular coverage angle improved from $28.3^{\circ}{\pm}12.3^{\circ}$ to $10.9^{\circ}{\pm}8.1^{\circ}$, lateral talo-first metatarsal angle improved from $-19.3^{\circ}{\pm}9.0^{\circ}$ to $-2.4^{\circ}{\pm}8.1^{\circ}$, and hindfoot alignment angle improved from valgus $11.9^{\circ}{\pm}10.0^{\circ}$ to $3.5^{\circ}{\pm}4.3^{\circ}$ at minimum 2-year follow-up. No complications occurred postoperatively. Conclusion: Calcaneo-stop procedure is a simple and very effective procedure for management of pediatric symptomatic flexible flatfoot that does not respond to conservative treatment.

When we introduce the BRT systems, it is very important to decide the operating factors, such as bus-stop locations or headway. If the factors are inappropriate, unessential expenses for the operator and users of the bus line may be caused, and it leads increase of social total cost. So, it is necessary that we consider users' origin and destination of each bus line when we set location of bus-stops and the optimal headway. Meanwhile, Smart Card System was introduced of fare collection for the Public Transportation Reform in Seoul last year. This new card system makes it possible to store up the information about bus operating and passenger's trip link. With these substantial information. we can estimate bus-stop-based O-D table. So, in this thesis, it was studied a systematic methodology to find the optimal location and headway for skip-stop bus system (as a type of first step for BRT). The proposed methodology in this thesis is expected to be useful to effect analysis or setting operating factors for skip-stop bus system in each bus line.

In order to search candidates for the treatment of myxosporean emaciation disease of olive flounder, Paralichthys olivaceus, in vitro and in vivo experiments were conducted using products such as Coxi-stop, Coxiclin, and BLEAN80. In the case of Coxi-stop, whose major component is toltrazuril, in vitro experiment using BF-2 cells showed a tendency of reducing the activity of myxosporea and did not exhibit cytotoxicity such as cell lysis. In the in vivo activity measurements, the experimental group immersed with Coxi-stop showed a lower cumulative mortality rate than the control group, this result is similar to the previous report that toltrazuril has a therapeutic effect on parasitic fish disease. This study suggests that toltrazuril is a potential candidate for the treatment of emaciation disease of olive flounder.

The purpose of this study is to propose an effective direction of data linkage for building the humanities assets one-stop portal service. For this purpose, We collected and analyzed the actual status of the domestic institution with humanities assets, and presented the linkage direction through analysis of the data held by the target organization. The results of this study are as follows: First, we proposed a classification system of humanities assets based on the reviewing the existing classification system on the subject of humanities assets. Second, we set up the categories of potential data that can be incorporated into humanities assets through a detailed analysis of the subject and type of data held by the subject institutions. Third, we analyzed the platforms of similar case organizations providing one-stop portal services for humanities assets and proposed the applicable meta fields when constructing one-stop system based on similarity.

In this paper, we resolved a trade-off problem of the blind equalizer based on the stop-and-go algorithm that is commonly used for QAM demodulation in CATV receiver. The stop-and-go algorithm has used the LMS(least mean square) algorithm in the updating operation of tap weights so that the structure of equalizer is simple, but there is a trade-off between convergence speed and steady state error as in the typical LMS algorithm. We used the variable step size algrithm to improve the convergence speed with the steady state error in the constant level. With respect to the same level of the steady state error, the variable step size stop-and-go algortihm improved convergence speed by about $36%{\sim}56%$ as compared with that of the constant step size algortihm.

SMT is an device that picks up electronic components and does precise placing onto PCBs. In order to do this, it stops in front of a camera installed in the middle to go over vision inspection. And after that it is move for placing. There are 16 different types of routes in this process. This paper compared to the moving time of three methods in the (sLa-Camera-pLa)type. The first method is stopping in front of the camera for vision inspection and placing components onto PCBs(stop-motion). The second method is moving in front of the camera for vision inspection without stopping(fly1-motion). The third method is inspecting the components when the speed of the X axis, the Y axis is the best and is placing components onto PCBs(fly2-motion). This paper shows the moving time of three methods is same. Therefore we proved that the stop-motion method can be placing in the fastest time without changing structure of the device in the (sLa-Camera-pLa)type.
