Korea has experienced many changes since modern hospitals started to be built. Among these changes, interest in 'Promotion of Curing environment', which is the most fundamental one of the hospital functions, has increased more and more. The lobby makes the first impression of a medical building and that is an important function. Recently, the lobby became highly valued not only as a waiting area or a pathway only but as a cultural area. The lobby is considered simply as a complex and busy area because it plays an important role in the building' communications and access systems and has various uses and functions. Based on the concept of curing environment, the lobby can be planned as a facility combining culture and medical functions by applying multi therapy.

The concentration of remaining formaldehyde contained in waste liquid emitted from the process of urea-formaldehyde microcapsule synthesis was analyzed by gas chromatography-mass spectrometry (GC-MS). Three factors that can affect on the reaction of formaldehyde were selected including pH, ammonium chloride input and temperature. The effect of these factors on the concentration of remaining formaldehyde was studied. When ammonium chloride input was 0.025g, microcapsules could not be obtained or core substance leaked out because of weak shell, and therefore this reaction condition would be inadequate. It was confirmed that the concentration of remaining formaldehyde could be minimized when the microencapsulation was conducted at 70℃ and pH 2.5 by using a ammonium chloride input of 0.050g. This study can make contribution to UF microencapsulation in safer working environment.

The goal of rotator cuff repairs is to achieve high initial fixation strength, minimize gap formation, maintain mechanical stability under cyclic loading and optimize the biology of the tendon-bone interface until the cuff heals biologically to the bone. Single row repairs are least successful in restoring the footprint of the rotator cuff and are most susceptible to gap formation. Double row repairs have an improved load to failure and minimal gap formation. Transosseous equivalent repairs (suture bridge technique) have the highest ultimate load and resistance to shear and rotational forces and the lowest gap formation. Even though the superior advantages of double row and transosseous equivalent repairs, those techniques take longer surgical time and are more expensive than single row repairs. Therefore single row repairs can be useful in bursal side partial thickness or small size full thickess rotator cuff tear.

It is necessary to build a quality-enhancing forest leisure sports facility according to values that value life quality, national forest policy. Vita Parcours (fitness trails) is found to be the activities highly convenient, so their introduction and promotion in Korea should be highly considered. field survey was necessary to explore the possibility of installing Vita Parcours. Several sites were selected, such as Asean recreational forest, Unaksan recreational forest, Yumyeongsan recreational forest, Saneum recreational forest, Jungmisan recreational forest and National center for forest therapy. At these locations, we explored the current status of forest facilities and forest trails. A total number of 31 exercise facilities has been identified and surveyed, some of which are located on the trails (2), alongside the trail (9), alongside trail boundaries (2) or represent facilities suitable for both outdoor and indoor exercise within the forest (18), all of whom provide location for 44 different exercise routines (flexibility exercises (23), endurance (12) and strength exercises (9)). Field work also included identification of forests paths, the total number of whom was 34 paths - 30 identified as trails, 2 as hiking trails, 1 as a forest path for relaxation and healing and 1 as an exploratory path. Regarding the structure and shape of these trails, 32 was straight in shape and only 2 designed as a circular forest trails. Average length of these trails was 652.2m with the highest and the lowest point altitude difference of 60m, on average. Saneum recreational forest provide the most suitable site/environment for Vita Parcours and as a result of this, Saneum recreational forest is proposed as a location to support the endeavors in promotion of these valuable forest fitness trails. Among the forest paths at this site, a forest path which has a length of 1.84km and 73.0m the highest and the lowest point altitude difference was selected as the most suitable, and may be equipped with necessary stations for exercise or obstacles. In addition, if these trails are to be introduced and welcomed by its users, we must assure that they are properly maintained.

최근, 과학 기술이 발달함에 따라 현장에서의 실시간 검사 및 자가 지단 등 질병 치유에 대한 사람들의 관심이 증가하고 있으며, 이에 따라 의료, 환경, 산업과 같은 많은 분야에서 바이오 센서에 대한 연구가 활발하게 이루어지고 있다. 그 중, EGFET는 전해질 속의 각종 이온 농도를 전기적으로 측정하는 바이오 센서로, 외부 환경으로부터 안전하고, 제작이 쉬우며, 재활용이 가능하여 비용을 절감 할 수 있다는 장점을 가지고 있다 [1]. EGFET는 감지부와 FET부로 분리된 구조를 가지고 있으며, 감지부의 감지막으로는 Al2O3, HfO2, $TiO_2$, SnO2 와 같은 다양한 물질들이 사용되고 있다. 그 중, SnO2는 우수한 감도와 안정성을 가지고 있는 물질로 추가적인 열처리 공정 없이도 우수한 감지 특성을 나타내기 때문에 본 연구에서 감지막으로 사용하였다. 한편, EGFETs 의 FET부로는 기존의 비정질 실리콘 TFTs 에 비해 10배 이상의 높은 이동도와 온/오프 전류비를 갖는 InGaZnO 를 채널층으로 사용한 TFTs 를 사용하였다. a-IGZO 는 넓은 밴드 갭으로 인해 가시광 영역에서 투명하며, 향후 투명 바이오센서 제작 시, 물질들 사이의 반응을 전기적 신호뿐만 아니라 광학적인 분석 방법으로도 검출이 가능하기에 고 신뢰성을 갖는 센서의 제작이 가능할 것으로 기대된다. 한편, a-IGZO TFTs 의 경우 우수한 전기적 특성을 나타냄에도 불구하고 소자 동작 시 문턱 전압이 불안정하다는 단점이 있으며 [2], 이러한 문제의 개선과 향후 투명 기판 위에서의 소자 제작을 위해서는 저온 열처리 공정이 필수적이다. 따라서, 본 연구에서는 저온 열처리 공정인 u-wave 열처리를 통하여 a-IGZO TFTs 의 전기적 특성 및 안정성을 향상시켰으며, 9.51 [$cm2/V{\cdot}s$]의 이동도와 135 [mV/dec] 의 SS값, 0.99 [V]의 문턱 전압, 1.18E+08의 온/오프 전류 비를 갖는 고성능 스위칭 TFTs 를 제작하였다. 최종적으로, 제작된 a-IGZO TFTs 를 SnO2 감지막을 갖는 EGFETs 에 적용함으로써 우수한 감지 특성과 안정성을 갖는 바이오 센서를 제작하였다.

ESG, which stands for Environmental, Social, and Governance, becomes a keyword in managing a company as it becomes an "indicator" that judge companies. Since the environment has suffered so much damage for economic development, it is now to reflect the enormous environmental costs of the future in the management standard rather than the immediate financial benefits at the expense of the environment. Compared to the days when corporate social responsibility (CSR) was discussed, ESG management has improved significantly as it requires practice beyond the declarative level, but the level of consideration for the environmental field is still not high. There may be many backgrounds, but the biggest problem may be the lack of understanding for other fields. Accordingly, this study aims to inform corporates of the need for investment in the environmental field by explaining ESG reviewed in the environmental field and ESG management required in the environmental field. Furthermore, another purpose is to inform them that ESG management is a win-win strategy that can have a meaningful effect not only in the environmental field where investment is received but also in terms of companies by explaining the benefits that companies can gain through this. To reach this goal, this study proposed a method of restoring a damaged ecosystem based on corporate investment, evaluating its effects based on carbon absorption capacity, and using it as a means of carbon neutrality practice as well as ESG management performance of a company.
