Recently, the instruction of the house ventilation system was necessary because of the recent construction trend and the legal ventilation frequency 0.7 point inside the house of common. It is general in the ventilation system that air supplies and returns to each room. But this system is not efficient when it comes to taking care of economic and construction efficiency. So, we study the instruction of unified ventilation system. The purpose of the system is to compare between original ventilation system and unified ventilation system. The results which it applies to actual apartment site are as followed. In the wind-amount test, unified ventilation system shows more wind amount than that of other existing facilities. Pressure loss shows the opposite results. This displays a more efficient ventilation ability and there is also an application possibility. Finally, we find unified ventilation system contains a brand new possibility and we recognize that more detailed-tests are required to unify ventilation system's practical uses.

미세플라스틱으로 인한 환경생태오염이 심화함에 따라, 기존 난분해성 플라스틱을 대체할 수 있는 친환경 소재에 관심이 높아지고 있다. 또한 석유 기반 자원의 고갈 및 이산화탄소 배출로 인한 온난화 환경문제 등으로 기존 석유계 플라스틱 소재를 대체 보완하는 친환경 천연소재 개발의 사회적 요구는 더욱 커지고 있다. 이에, 생분해가 가능한 천연자원으로부터 다양한 물리 화학적 엔지니어링 기능성을 추가하여 플라스틱의 환경문제를 극복하려는 시도들이 활발히 진행되고 있다. 본 기고에서는 나노셀룰로오스, 생분해성 고분자, 멜라닌 소재를 중심으로 친환경 기능성 천연소재의 최신 연구 동향을 소개하고, 이의 기존 합성 플라스틱 대체응용 방안의 가능성을 탐색한다.

Gears are reliable and efficient power transmission elements. They have been widely used in all kinds of machinery. Nowadays, resource conservationㆍenergy conservationㆍenvironmental improvements from the request of the compact, light weight, high efficiency, low costㆍHigher efficiency is required. Tooth root and bottom profiles of cylindrical gears affect bending fatigue life, but they are hard to measure with conventional gear measuring machine(GMM), because GMM is normally customized to measure only gear working flanks. The authors try to develop a new type of GMM by installing an extra 3D scanning probe and control software to measure tooth root and bottom profiles. First, in order to measure in various directions, a 3D scanning probe has been attached to the GMM developed. Next, calibration algorithm has been developed. Deviations of the calibration results are measured and it is found that systematic error must be caused by heat from driving motors. A new alternative GMM with driving motors generating less heat was designed and two GMMs are compared. Finally, 3 Dimension measurement of tooth root and bottom profiles of cylindrical gears is described.

The pattern and total amount of nitrous oxide (N₂O) emission can be affected by characteristics of arable soil and weather condition associated with geographical differences. The objective of this study was to determine the effect of weather conditions and soil properties on N₂O emission from paddy soils in geographically different three regions of South Korea. Field trials were established at three locations (Jeonju, Miryang, and Suwon) in South Korea and the rice (Oryza sativa L.) was transplanted and harvested in May and October 2020 at all locations, respectively. Urea was applied at the rates of 0, 90, 135, and 180 kg N ha<SUP>-1</SUP> at all locations. Mid-season drainage was conducted for 14 days, 5 weeks after transplanting at all locations. Daily N₂O flux and the cumulative N₂O emission, and weather conditions during growing season of rice and soil properties at harvest time were measured. The peak of N₂O flux appeared after drainage during growing season of rice, excepting Jeonju. Compared to the 0 kg N ha<SUP>-1</SUP> treatment group, the cumulative N₂O emissions of 90, 135, and 180 kg N ha<SUP>-1</SUP> treatment groups were 0.23, 0.44, and 0.63 kg ha<SUP>-1</SUP> in Jeonju, 0.16, 0.89, and 1.37 kg ha<SUP>-1</SUP> in Miryang, respectively, were increased by 1.40, 1.52, and 1.04 kg ha<SUP>-1</SUP> in Suwon. The cumulative N₂O emissions increased with application rate of urea, but in the case of Suwon, it did not increase significantly. Although there was no significant difference, Miryang (0.74 kg ha<SUP>-1</SUP>) had the highest mean cumulative N₂O emission, followed by Jeonju (0.42 kg ha<SUP>-1</SUP>) and Suwon (0.16 kg ha<SUP>-1</SUP>). Suwon and Jeonju had 329 and 488 mm more precipitation than Miryang, respectively. The nitrogen content of the study soil was 1.01, 2.24, and 1.16 g kg<SUP>-1</SUP>, respectively. So, precipitation and soil nitrogen content were related to the cumulative N₂O emission. Consequently, cumulative N₂O emissions between the three regions were related to precipitation and soil nitrogen content.

Recently, the instruction of house ventilation system was necessary because of the recent construction trend and the legal ventilation frequency 0.7 point inside the house of common. It is general in the ventilation system that air supply and return to each room. But that system is not efficient in the economic and construction circle. So we study the instruction of unify ventilation system. The purpose of system is to compare the original ventilation system and unify ventilation system. The results which it applies from actual apartment site are as following. In the wind-amount test, unify ventilation system shows more wind amount than the existing facilities. Pressure loss shows the opposite results. This displays a more efficient ventilation ability and there is also an application possibility. Finally, we finds unify ventilation system's a new possibility and we recognize that more detailed-tests are required to unify ventilation system's practical use.
