이 연구에서는 제주도 지역에서 태풍에 의해 야기되는 조풍(潮風) 발생 및 식생에 나타난 피해의 시 공간적 특징을 밝히고자 하였다. 이를 위해 2012년 8월 하순 제주도를 강타한 태풍 볼라벤(BOLAVEN)의 통과시 기상자료를 분석하고 이후 야외답사를 수행하여 제주도 식생에 나타난 조풍해 정도를 조사하였다. 그 결과, 조풍해는 주로 제주도 남부 및 동부 해안지역에서 발생한 것으로 나타났으며, 태풍이 동반한 강한 남동풍과 상대적으로 적은 강수량이 그 원인으로 분석되었다. 조풍에 의해 해안에서 약 8km 범위 내의 삼나무(Cryptomeria japonica)와 해안지역의 곰솔(Pinus thunbergii)을 포함한 대부분의 식생이 피해를 입었으나, 그 피해정도 및 회복력은 수종별로 차이가 있었다. 조풍에 의한 식생 피해를 줄이기 위해서는 강풍성 마른 태풍이 접근 시 조풍해 발생을 예측하고 방제대책을 마련하는 것이 필요하다.

네일 산업이 발전함에 따라 트렌드를 주도하는 네일 시술을 통한 자연 네일 손상에 대한 우려 및 네일제품에 대한 관심이 증가하고 있다. 본 연구에서는 보다 현실적으로 도출된 네일 손상을 감소시키는 네일 융복합보강제에 대한 연구를 하고자 한다. 특히 네일 미용인들의 네일 보강제에 대한 사용실태와 인식도를 파악하고자 하며 이를 통해 보다 건강하고 아름다운 네일 미용을 만드는데 일조하고자 한다. 본 연구의 내용은 먼저 네일 미용과 네일 손상 및 네일 보강제에 대한 개념과 선행연구 경향을 살펴보고, KSDC 온라인 설문조사를 실시하였으며 그 결과를 KSDC 고급 통계 프로그램을 사용하여 통계 처리하였다. 보강제에 대한 주요 인식에 대한 문항에서 보강제의 특징, 효과, 사용방법, 시술순서는 대체로 잘 인식하고 있는 것으로 나타났고 성분 인식의 경우는 보통으로 나타났다. 네일미용은 최근 들어서는 건강관리 차원의 실용성이 중시되고 있다. 자연네일의 건강한 유지를 위하여 본 연구가 네일보강제 연구의 기초자료가 되기를 희망하며 보다 구체적인 네일 보강제 성분에 대한 연구를 앞으로의 연구 과제로 남기고자 한다.

Recently damages caused by the additional costs and degradation in durability combined deterioration due to plain concrete deterioration has occurred. In particular, in the case of the finish that is not exposed to the outside air in the concrete to respond to the harsh environment (freeze-thawing, calcium laying, etc.), to establish a quality control way for the process and the concrete mix design for it.

Real-time control of on-site construction, based on high quality data, is essential to identify discrepancies between actual and planned performances. Additionally, real-time control enables timely corrective measures to be taken when needed to reduce the damages caused by the discrepancies. The focus of the presentation will be on our work, which uses automated data technologies to collect data needed for real time control.

It is widely accepted that free-radical induced oxidative damages are involved in pathogenic processes of major diseases including cancer, atherosclerosis, rheumatoid arthritis and diabetes. A number of epidemiological studies have indicated that frequent consumptions of plant foods rich in antioxidants reduce the risk of developing cancer and cardiovascular diseases, while many intervention trials have failed to prove the protective role of major dietary antioxidants.(omitted)

Recently, tunnel structure is being widely used in railway or roadway construction projects because earthwork causes large cutting and damages in environmental factors. However, there are many changes of design by different items comparing with design phase in tunnel structure by uncertain drawings. This study develops a standard process for the change of design to reduce change orders in construction phase.

Various types of dampers are widely adopted to reduce the seismic damages in bridges. However, dampers may be the improper solution especially in moderate seismic regions because dampers are costly for installation and require constant maintenance during life cycle. In this study, energy-dissipating sacrificial device is proposed, which sacrifices easily substitutable bridge members and dissipates the excessive energy during seismic excitations. In turns, the inelastic behavior of sacrificial members reduces the input energy of the major members, such as piers in bridges, and may prevent the major members from serious malfunction. A simplified mechanical model is developed to represent the behavior of sacrificial devices installed in a bridge. The hysteresis energy of piers is analyzed to certify performance of device under seismic loads applied to this mechanical model. The results from this study show that the proposed sacrificial energy-dissipating device can decrease excessive hysteresis energy and reduce the damage of piers under seismic excitation. Therefore, economical enhancement of the seismic performance of bridges may be possible by employing the proposed sacrificial energy-dissipating devices.

Hasa TM/TC system is composed of one control center, two reservoirs, six pumping stations and twelve canal systems. For this system we developed water management program which includes flood forecast program, drought reduction program, irrigation scheduling program and database program. With these program we expect that operators can improve the irrigation efficiencies of the irrigation systems due to the timely irrigation on a right place, in a proper quantity and reduce the cost of maintenance and reduce flood and drought damages of the Hasa district. In agricultural engineering respect, the databases including water level, rainfall, the amount of flowing can be useful to the researcher who make a study of hydrology and hydraulics in rural area. Water management program records all of the TM/TC data to MOB format file per 10 minutes.

Four field experiments were carried out from 1998 to 1999 and from 1999 to 2000 growing seasons of potato to investigate the relationship between leafminers and Alternaria alternata. The experiments established differential susceptibility among potato varieties to alternaria leaf necrosis, relationship between leafminer infestation and the level of necrosis, use of insecticides to reduce leafminer and leaf necrosis damages, and use of polyester fleece to eliminate leafminer and eventually reduce leaf necrosis. Results of the study indicate that control of leafminer is of primary importance because this will automatically lead to control of the damage caused by A. alternata.

Recently, the construction of infrastructures has been booming and acceleratin to keep up with rapid economic growth. Consturction activities and operation of transportation facilities caues unfavorable effects such as civil petitions associated with vibration-induced damages or nuisances. Vibration-controlled mixtures are latex, rubber powder and plastic resin, which have been deternimed to reduce vibration by and large reduce vibration. KS F2437 and travel time method have been used to figure out 1st natural frequency and dynamic elastic moduli. Dynamic damping ratios have been computed by adopting the polynomial curvefitting method and the geometric analysis method on the frequency spectrum curve, of which results have been compared and analyzed hereon.
