Dimethomorph is a novel fungicide with a high level of activity against diseases induced by certain Oomycetes, including fungal populations that are resistant to other products. In several ways, this fungicide illustrates the opportunities and challenges presented by many modern pesticides. The specific mode of action, which affects cell wall formation, is associated with a very high level of performance and low dose rates under field conditions. These low dose rates, combined with a low level of toxicity to non-target organisms present an outstanding safety profile. This same highly-specific mode of action, however, limits the spectrum of activity and suggests the need for a resistance management plan, both of which must be addressed in new product development. In addition, the biological and physiochemical properties of this, and other new products are not adequately described by the traditional classification of fungicides into“protectant”and“systemic”types. These unique profiles provide novel and useful products for disease control.

This study analyzes the problems, which the residential inner area has, and proposes systematic and gradual progressing improvement plan for the residential environment in the inner area. Also, planning instruction is proposed through the case study of parcel·jointed complex housing. This study can be concluded as below: (1) Improvement plans sub-divided into promoting districts and inducing districts of the residential inner area are proposed. (2) Necessity for construction of streets is proposed in order to compensate existing problems in sites. (3) Necessity of complex housings is proposed fur roadsides of household unit or small-sized annexation of parcel. (4) Collecting design examples and existing literatures, the planning guideline for jointed parcel complex housing is proposed based on the established relation with a whole surface of streets, formation and distribution of purposes and increased role of exterior space.

This study intends to make a counterproposal for re-building existing high-rise/high-dense buildings and for planlessly re-constructing multi-dwellings. Also, it proposes the plan instruction fur reconstruction by small collective housings through annexing parcels in the residence Inner area. This study can be summarized as below: (1) Remained site generated by site boundaries can be utilized by annexing two or more parcels. (2) Vacant lots between buildings can be utilized as building space or common space by small-sized annexation. (3) Bad effect of residential environment caused by simultaneous development of total blocks can be minimized. (4) Formation of site size and plane, which are advantageous to reconstruction, is available. (5) Accessibility to neighboring roads can increase. (6) Residents' participation in development can increase in economical and planning aspect. In order to utilize these planning instruction, residents' participation and improved public ownership system for parcel annexation are required.

Highly oriented diamond films were deposited on a (100) silicon substrate by bias enhanced nucleation technique. Both plan-view and cross-section TEM were applied to study the nucleation and growth mechanism of diamond grains. Randomly oriented polycrystalline diamond grains with internal microtwins were observed at the nucleation stage while defect free regions were retained at the growth stage and were apparently related with the epitaxy of diamond films. From our experimental results, the nucleation and texture formation mechanism of diamond films is discussed.

This study is about the residential district structure of Gyeryong ceramic art village in Gyeryong ceramic art village is a residential district for potters who succeed to and develop Gyeryong ceramic art. The external appearance of Gyeryong ceramic art village seems like being fixed and simplified. The creative space is either detached or attached to a living room. The relation between inner and outer space is that is directly connected to a garden. In the characters of major spaces, the formation of a workshop is the most important part of a house. And, an exhibition equipment and an oven are connected to the workshop. According to the study, a house, which is designed without an architect's help is simple and has a different form from a house designed by an architect.

Merging of two supermassive black holes would generate gravitational waves that can be detected by the Pulsar Timing Array (PTA) in the nHz band. In order to assess the plausibility of GW detection with PTA and to develop the data analysis scheme, it is important to understand the underlying properties of black holes and black hole binaries. In this work, we present mass and redshift distributions of black hole mergers using the Horizon Run 5 (HR5) data and discuss their implications for GW detection. We find a general conjecture about the black hole merger tree is true with the Horizon Run 5. For example, a) relatively lighter black holes merge at higher redshifts and b) binary mergers do contribute to the formation of more massive black holes toward low redshifts. We also present our plan to use the black hole properties extracted from the HR5 data in order to generate simulated GW signals to be injected into actual PTA data analysis pipelines. Mass and distance obtained from the HR5 would be key ingredients to generate a more realistic PTA source data set.

Rupture of the pectoralis major muscle typically occurs in the young, active male. Acute management of these injuries is recommended; however, what if the patient presents with a chronic tear of the pectoralis major? Physical exams and magnetic resonance imaging can help identify the injury and guide the physician with a plan for management. Nonoperative management is feasible, but is recommended for elderly, low-demand patients whose functional goals are minimal. Repair of chronic tears should be reserved for younger, healthier patients with high functional demands. Although operative management provides better functional outcomes, operative treatment of chronic pectoralis tears can be challenging. Tendon retraction, poor tendinous substance and quality of tissue, muscle atrophy, scar formation, and altered anatomy make direct repairs complicated, often necessitating auto- or allograft use. We review the various graft options and fixation methods that can be used when treating patients with chronic pectoralis major tears.

Bone loss from the kerf of the sawblade may influence the final outcomes when employing three-dimensional-printed surgical guides. However, no studies have systematically addressed saw blade-induced bone loss. This study aims to quantify bone loss and propose a reduction guide to minimize the fracture gap. The postoperative gap tended to decrease as the amount of gap compensation increased. Osteotomy gaps can be attributed to the thickness of the saw blade, and the proposed methodology addresses this surgical error. Surgeons can proactively plan and design reduction guides with applied compensation using the method described in this study.

본 연구는 낙동강 하류원수를 정수처리하는 정수장에서 전염소 처리시 pH 조절, 오존처리, 응집이 THMs 생성에 미치는 영향을 평가하기 위해 수행하였다. 원수의 pH를 낮추면 전염소 처리에 의해 THMs 생성이 저감되었다. pH를 9.5에서 9.0로 낮추면 THMs 생성이 18.3%, 9.0에서 8.0으로 낮추면 14%, 8.0에서 7.0으로 낮추면 7%, 9.5에서 8.0으로 낮추면 29% 감소되었다. 염소처리 전에 저농도의 오존($0.11{\sim}0.48mg{\cdot}O_3/DOC$)을 주입하면 오존을 주입하지 않은 경우에 비해 THMs 생성을 6~24% 정도 저감시킬 수 있었다. 전오존 1.0 mg/L을 주입한 원수에 염소 2.5 mg/L를 주입하고 alum 40 mg/L, 황산 6 mg/L를 주입한 경우 THMs 생성농도가 염소만 처리한 경우에 비해 42% 감소하였다. 정수처리공정에서 전오존 처리 후에 염소를 투입하고 응집이나, pH 조절을 하면 취수구에서 pH만 낮추는 경우에 비해 THMs 제어에 더 효과적이다. 염소 2.5 mg/L를 주입한 후 alume 40 mg/L 주입하여 응집실험을 한 결과, THMs 생성농도가 염소만 투입한 경우에 비해 pH 저하로 인해 19%, 천연 유기물질(NOM)의 제거로 18% 정도 저감되었다. 응집은 pH 저하와 유기물 제거를 동시에 유발하기 때문에 pH를 낮추는 경우에 비해 THMs 생성농도 저감에 효과적이었다.

이 논문의 목적은 한국 경제자유구역이 지니는 '네트워크 도시'의 제도적 구성과 운영의 한계를 영남권의 대구경북경제자유구역을 사례로 서설적 차원에서 검토하는 것이다. 경제자유구역의 지정 및 운영에 관한 법 제도의 특성은 관련 주체들이 다층적이면서도 수직적 또는 수평적인 거버넌스를 구축하고 있는 것을 특징으로 하고 있다. 그러나 실제로 지역 주민이 자신들의 재산권을 행사하는 데 있어서 의견수렴 기간이 짧아서, 이로 인한 정책 실패의 개연성도 높을 수 있다는 특성을 지니고 있음과 동시에 광역시 도, 기초지자체, 경제자유구역청 간 행정적으로 강한 수직적 거버넌스 성향이 나타난다. 대구경북경제자유구역을 네트워크 도시 특성에서 살펴 볼 때, 계획단계에서 네트워크 도시의 특성을 반영했음에도 불구하고, 실행단계에서는 단위 지구별로 성과지향형 거점개발 전략을 취하고 있어서 계획과 실행 간 큰 차이를 보이고 있다. 특히, 대구경북경제자유구역청의 행정 조직을 개발 중심에서 투자 중심을 거쳐 광역 시 도 중심으로 개편한 점은 계획단계에서 제시한 네트워크 도시 전략으로서의 위상이 운영 단계에서 퇴색하면서 개별 지역주의로 회귀하고 있는 현실을 나타낸다. 이러한 특징은 지구 지정, 재지정, 해제를 둘러싼 단위 지구의 변경과정에서 더욱 강하게 나타나면서 경제자유구역에 기초한 네트워크 도시의 구성과 운영의 한계를 보이고 있다.
