Slaughter of cattle, pigs, and chickens has increased continuously. In particular, slaughter of chickens has been grown up about 150% in 2010 than that in 2003, that is approximately 120,000 tons. All of them are underwent consigned treatment even though those can be used as a resource and an energy source. With this regards, THR (Thermal Hydrolysis Reaction) leads to reduce water content drastically (<30% in sludge cakes). In addition, Dehydrated solid would be re-used as solid fuels (SRF) as well. In this study, We have applied THR to a plant (10 ton/day) on the basis of our lab and pilot results. Water content of sludge cakes showed with a ranges of 30 to 40% after solid-liquid separation. Dairy SRF produced 1.5 ton/day and its heat capacity for SRF has 6,500 kcal/kg. This gave the steam produced about 12 ton/day throughout the plant operation, suggesting that THR system would expect energy savings.

This study focused on the alternative to estimate the demand of employment in Kenya logistics. First of all, it investigated the importance and necessity of search about the present circumstance of the country’s industry. Next, it reviewed respectively the concept and limitation of several previous models for employment, including Bureau of Labor Statistics, USA; ROA, Netherlands; IER (Institute for Employment Research), UK; and IAB, Germany. In regard to the demand forecasting of employers in logistics, it could anticipate more realistically the future demand by the time-lag approach. According to the findings, if value of output record 733,080 KSH million in 2015 and 970,640 in 2020, compared to 655,222 in 2013, demand on wage employment in logistics industry would be reached up to 95,860 in 2015 and 104,329 in 2020, compared to about 89,600 in 2012. To conclude, this study showed the more rational numbers about the demand forecasting of employment than the previous researches and displayed the systematic approach to estimate industry manpower in logistics.

Tuned Mass Damper (TMD) is a prominent mean of controlling structural vibration. Typically the TMDs are installed at the top of the structure. In this study, the effectiveness of the multiple tuned mass dampers (MTMD) distributed along with the height of structure is investigated for seismic loading. A ten storey building with lateral degree of freedom is modeled with distributed tuned mass dampers in the platform of MatLab R2010a. Though the first mode of a MDOF system dominates in response of the structure, it is also observed that the other mode can also have a significant role in the response reduction. Suitable location for the installation of the TMDs and there tuning frequencies are selected based on the mode shape and frequencies of the uncontrolled structure respectively. It is observed that distributed TMD is more effective than Single TMD and Multiple TMD installed at top of the structure in response reduction.

Forbush Decreases (FD) are transient, sudden reductions of cosmic ray (CR) intensity lasting a few days, to a week. Such events are observed globally using ground neutron monitors (NMs). Most studies of FD events indicate that an FD event is observed simultaneously at NM stations located all over the Earth. However, using statistical analysis, previous researchers verified that while FD events could occur simultaneously, in some cases, FD events could occur non-simultaneously. Previous studies confirmed the statistical reality of non-simultaneous FD events and the mechanism by which they occur, using data from high-latitude and middle-latitude NM stations. In this study, we used long-term data (1971-2006) from middle-latitude NM stations (Irkutsk, Climax, and Jungfraujoch) to enhance statistical reliability. According to the results from this analysis, the variation of cosmic ray intensity during the main phase, is larger (statistically significant) for simultaneous FD events, than for non-simultaneous ones. Moreover, the distribution of main-phase-onset time shows differences that are statistically significant. While the onset times for the simultaneous FDs are distributed evenly over 24- hour intervals (day and night), those of non-simultaneous FDs are mostly distributed over 12-hour intervals, in daytime. Thus, the existence of the two kinds of FD events, according to differences in their statistical properties, were verified based on data from middle-latitude NM stations.

We have launched an investigation for Embryonic Development, Larvae and Juvenile Morphology, of Buenos aires tetra in order to build basic data of Characidae and fish seeding production. We brought 50 couples of Characidae from Bizidduck aquarium in Yeosu-si, Jeollanamdo, from Korea on March of 2015. We put them in the tetragonal glass aquarium (50×50×30 cm). Breeding water temperature was 27.5~28.5°C (mean 28.0±0.05°C) and being maintained. The shape of fertilized egg was round shape, and it was adhesive demersal egg. The egg size was 0.63~0.91 mm (mean 0.74±0.07 mm, n=20). After getting fertilized egg, the developmental stage was gastrula stage, and embryo covered almost two-thirds of Yolk. Incubation was happened after 16 hours 13 minutes from gastrula stage, and the tail of juvenile came out first with tearing egg capsule. Immediately after the incubation, prelarvae had 3.78~3.88 mm length (mean 3.84±0.04 mm, n=5), and it had no mouth and anus yet. 34 days after hatching from the incubation, juvenile had 8.63~13.1 mm (mean 10.9±1.66 mm), and it had similar silver-colored body shape with its mother.

We have carried out photometric follow-up observations of bright transiting extrasolar planets using the CbNUOJ 0.6 m telescope. We have tested the possibility of obtaining high photometric precision by applying the telescope defocus technique, allowing the use of several hundred seconds in exposure time for a single measurement. We demonstrate that this technique is capable of obtaining a root-mean-square scatter of sub-millimagnitude order over several hours for a V ~10 host star, typical for transiting planets detected from ground-based survey facilities. We compared our results with transit observations from a telescope operated in in-focus mode. High photometric precision was obtained due to the collection of a larger amount of photons, resulting in a higher signal compared to other random and systematic noise sources. Accurate telescope tracking is likely to further contribute to lowering systematic noise by exposing the same pixels on the CCD. Furthermore, a longer exposure time helps reduce the effect of scintillation noise which otherwise has a significant effect for small-aperture telescopes operated in in-focus mode. Finally we present the results of modelling four light-curves in which a root-mean-square scatter of 0.70 to 2.3 milli-magnitudes was achieved.

Earth’s magnetopause separating the fast and often turbulent magnetosheath and the relatively stagnant magnetosphere provides various forms of free energy that generate low-frequency surface waves. The source mechanism of this energy includes current-driven kinetic physical processes such as magnetic reconnection on the dayside magnetopause and flux transfer events drifting along the magnetopause, and velocity shear-driven (Kelvin-Helmholtz instability) or density/ pressure gradient-driven (Rayleigh-Taylor instability) magnetohydro-dynamics (MHD) instabilities. The solar wind external perturbations (impulsive transient pressure pulses or quasi-periodic dynamic pressure variations) act as seed fluctuations for the magnetopause waves and trigger ULF pulsations inside the magnetosphere via global modes or mode conversion at the magnetopause. The magnetopause waves thus play an important role in the solar wind-magnetosphere coupling, which is the key to space weather. This paper presents recent findings regarding the generation of surface waves (e.g., Kelvin- Helmholtz waves) at the Earth’s magnetopause and analytic and observational studies accountable for the linking of the magnetopause waves and inner magnetospheric ULF pulsations, and the impacts of magnetopause waves on the dynamics of the magnetopause and on the inner magnetosphere.

보습제는 피부과에서 가장 흔하게 사용하는 제품 중 하나로, 피부장벽을 유지시키고 피부가 촉촉하고 건강하게 보이게 하며, 영유아의 정상적인 피부발달에 매우 중요하게 작용한다. 하지만 보습제 도포가 정상 영유아의 피부에 어떠한 영향을 미치는지에 대한 연구는 제한적이다. 이에 건강한 정상 영유아에서 일반적인 보습제 도포가 피부에 미치는 영향을 알아보고자 본 연구를 진행하였다. 31명의 피부염이 동반되지 않는 건강한 6 - 36개월 연령의 영유아를 대상으로, 하루 2회 목욕 후 눈과 기저귀 착용 부위를 제외한 전신에 존슨즈 베이비 내츄럴너리싱 로션을 4주간 도포하였다. 임상적 평가는 도포 전후, 1주, 4주에 실시하였다. 매 방문시 피부수분도와 경표피수분손실도, 피부산도 및 거칠기를 측정하였으며 피부표면을 촬영하여 비교하였고 보습제 도포 후 발생한 피부 발진을 포함한 모든 부작용을 기록하였다. 보습제 도포 후 피부수분도는 통계적으로 유의하게 증가하였으며, 경표피수분손실도와 거칠기는 통계적으로 유의하게 감소하였다. 피부산도는 약산성으로 조절되었으며, 육안적으로 피부표면은 매끄럽게 변화한 것이 관찰되었다. 임상 시험 기간 동안 부작용은 관찰되지 않았다. 본 실험을 통해 보습제 도포가 영유아의 피부에 있어 수분을 증가시키고, 피부장벽기능 증강과 약산성의 피부산도 조절 및 거칠기의 호전을 야기하며, 4주간의 보습제 도포가 미치는 영향의 정도를 확인할 수 있었다.

Purpose Investors, creditors, – governments, and others make decisions using reasonable information provided by others. In many cases, the users of this information have goals and objectives conflicting with those of the information’s producers, indicating the need for external auditors. Research design, data, and methodology – Competition in auditing has noticeably intensified globally, especially in developed countries. This means that auditors are striving to increase the efficiency of their methods. In recent years, risk-based auditing has become prominent among these efforts. In risk-assessment auditing, the auditor may directly affect the effectiveness and efficiency of the audit. Results – As a central framework, the risk assessment process improves audit quality and effectiveness such that the audit will lead to necessary changes. Previous studies have shown that risk assessment affects the nature, timing, and content of audit procedures. Conclusions – In the planning stage of an audit, audit risk assessment may identify any inappropriate or inefficient distribution of resources or determine whether the results of an audit will be ineffective or incorrect. Thus, assessing audit risk is a critical task.

The purpose of this study is to evaluate which clinicopathologic factors are associated with central lymph node metastasis (CLNM) in papillary thyroid carcinoma (PTC). A total of 402 cases of PTC were divided into two groups: CNLM (+) and CLNM (-). In univariate analysis, CLNM showed correlation with sex, tumor size, multifocality, bilaterality, extrathyroid extension, and distance from the capsule. In multivariate analysis, male gender, >1 cm of tumor size, multifocallity and extrathyroid extension were significant risk factors for CLNM. Findings of this study suggest that clinicians should pay attention to the above mentioned significant risk factors when examining lymph node (LN) for deciding LN dissection.

최근 기후 변화에 따른 게릴라성 호우에 의한 전 세계 도심 속 산지 지역에서 토석류의 발생 빈도수가 증가하고 있으며, 이 결과 더 많은 인명피해와 주요 시설물 파괴 등의 피해가 사회적 큰 문제로 대두되고 있다. 현재까지는 도심지역 재해 관리 및 피난 계획 수립 시, 토석류 범람은 별도로 취급되어 피난 권고 시스템이 구축되고 있으나 피난계획 수립 시, 재해 발생 가능성을 고려한 여러 재해를 기반으로 통합적인 대책 수립이 필요하며 향후, 현재보다 더 큰 강우가 발생 할 가능성이 굉장히 크며 이에 대한 대책 수립의 중요성 또한 강조되고 있다. 본 연구에서는 실제 지역에서의 토석류의 유동형태를 파악하고, 외력조건으로 DAD 분석을 통해 가능최대 강우량과 유출량을 산정하며 주거지 지역에서의 토석류 영향범위 파악을 목적으로 한다. 실제 지역에서의 토석류 특성을 분석하기 위해 토석류 흐름 패턴, 퇴적 깊이, 도달속도, 발생된 토사량 및 토석류 이동거리를 평가했다. DAD 해석 결과, 피크 시간 강우량은 국지성 호우에 의해 약 135 mm, 24시간 누적 최대강우량은 태풍에 의한 호우로 약 544 mm로 조사 되었다. 또한 토석류에 의한 영향범위를 파악 하였다.

이전 연구에서 포도 품종별 및 부위별 생리활성 물질을 분석한 결과 MBA 품종의 송이줄기 부위에서 transresveratrol 함량이 다른 품종에 비해 수십배 높았다. 이를 바탕으로 포도주 제조 시 버려지는 비가식 부위인 송이줄기 를 농도별로 첨가해 발효 중 발효액 및 포도주의 폴리페놀 함량을 조사하였다. 송이줄기 첨가량에 따른 발효액의 발효 중 적색도, 총안토시안 함량, 총폴리페놀 및 탄닌 함량은 발효후기로 갈수록 송이줄기 첨가에 따라 유의적으로 증가 하였고, 포도주에서도 같은 경향을 보였다. 반면 포도주의 휘발산 함량은 송이줄기 첨가량이 증가할수록 감소하는 경향을 보였다. 발효액 및 포도주의 폴리페놀 성분을 분석 한 결과 catechin(8.16∼23.08 mg/L)함량이 가장 높았으며 gallic acid(2.32∼3.28 mg/L), trans-resveratrol(1.38∼3.27 mg/L)및 ferulic acid(1.51∼1.59 mg/L) 순서로 함량이 높았 다. MBA 포도주의 항산화활성을 DPPH IC50로 측정한 결과 송이줄기 함량에 비례해 활성이 증가하였으며, 송이줄기 5% 첨가한 포도주(12 mg/L)는 ascorbic acid의 DPPH IC50 (67 mg/L)보다 낮은 농도에서 높은 항산화활성을 나타내었 다.

본 논문은 미국 남부지역 특화작물인 머스커다인 포도의 부분별 추출물의 항산화능 및 항균활성을 구명하기 위한 목적으로, Higgins, Jumbo, Noble 3종의 머스커다인 품종을 대상으로 하여 포도의 과피/과육부분과 종자부분을 추출하 여 실험에 사용하였다. 각 추출물에 대하여, 항산화능은 총페놀함량 및 라디칼 소거능(Scavenging activity 및 EC50) 을, 항균활성은 E.coli K12에 대한 최소생육저해농도 (minimum inhibitory concentration, MIC)를 조사하였다. 종 자 추출물의 총페놀함량은 231.24~294.81 mg/mL GAE로 과피/과육 추출물에 비하여 높은 함량을 보였다. 또한 Higgins품종의 종자 추출물이 가장 우수한 라디칼소거능 (EC50=0.026 mg/mL)을 나타내, 종자추출물이 과피/과육추 출물보다 우수한 항산화능을 보유하였다. 반면, E.coli K12 에 대한 항균활성은 Higgins 품종의 과피/과육추출물이 40 mg/mL의 MIC를 보임으로써 가장 우수하였다. 따라서, 본 연구는 머스커다인 포도 추출물이 천연 유래의 항산화 및 항균 기능성을 보유한 소재로 활용될 수 있는 잠재적 가치 를 제시하였다.

본 연구에서는 부산 해운대 화재사고(2010년)와 같은 고층 건축물 화재시, 외벽 외장재를 통한 수직화재확산 피해를 저감시키기 위하여 도입이 검토 되고 있는 실대형 시험법의 교정 절차에 대한 연구를 수행하였다. 이를 위하여 일본 동경이과대학 화재과학연구실의 외장재 시험장치를 이용한 교정시험을 실시하였으며, 화원으로는 도시가스를 사용한 경우와 대체화원인 목재클립을 적재한 화원 각 2경우에 대하여 시험을 실시하였다. 측정항목은 각각의 경우에 대하여 열류량과 온도를 측정하였다. 교정시험결과 두 경우 모두 표준시험법에서 제시하고 있는 열류량 기준(55 kw/m2)보다 3배가량 높은 150 kw/m2 측정되었으며, 온도 기준(800 ℃) 역시 1,000℃ 상회하는 결과를 나타내었다. 이는 표준시험법에서 가스의 공급량만을 규정하고 있을 뿐 공기 공급량 및 실험시 후드의 높이 그리고 주변 기류 조건등 기타 조건에 대한 명확한 세부 조건이 제시하지 않아 생기는 문제로 분석된다. 따라서, 이로 인한 균일한 화재조건 구현이 이루어지 어려울 것으로 판단되며, 특히 외장재의 수직화재확산 정도를 평가하기에는 너무도 가혹한 화재조건인 것으로 평가되었다. 본 실험을 통하여 표준시험법의 보다 명확한 화재원 확립 및 교정 시험 절차 개정을 위한 기초 자료를 수집하였으며, 이를 토대로 한 개정 심의 활동이 전개되어야 할 것으로 평가 되었다.

According to a recent analysis of NASA, the year 2014 now ranks as the warmest on record since 1880. Africa is widely held to be highly vulnerable to future climate change related hazards, and Ethiopia is often cited as one of the most extreme examples. The country’s economy is highly exposed to climate variability and extremes and the nature of agriculture, primarily rain-fed is sensitive to fluctuations in rainfall, which forms the basis of the economy supporting roughly 42% GDP and 85% employment. Wahlström M (2009) reported that over the last two decades (1988-2007), 76% of all disaster events were hydrological, meteorological or climatological in nature. In this review, a great concern is given for extreme conditions (flood and drought) particularly climate change related hazards and tries to look at the challenges, mitigation and policies. Climate change, drought and flood will continue to be a primary concern for many Ethiopian and even agricultural production and water supplies will become more severely diminished. Starting from 1970-1996 droughts and the resulting food shortage have affected millions and cause for the death of a significant number of people and in 2009 Ethiopia has experienced a delay in the main rainy season, particularly in northeastern areas, resulting in 50-70 % of agricultural land being sown for cropping. Ethiopia has also experienced a major flood in 1988, 1993, 1994, 1995, 1996 and 2006 and climate change, including extreme events like drought and flood affected areas will likely become more widely spread. Recently, flash floods affected big cities, including Addis Ababa and Dire Dawa (death of 300 people) and result in considerable damage to lives, livelihoods and property. Despite the hugely damaging effect that natural and man-made disasters have on Ethiopia’s economic development, little is done to prevent them. There are significant challenges to reduce climate change related hazards, but linking of climate change adaptation with disaster risk reduction and effective strategies to prevent hazards from becoming disasters and managing those disasters that do occur would make a lasting contribution to the quality of life and sustainable livelihoods. Several factors contribute to Ethiopia’s high vulnerability to disasters, but here the authors will focus on institutional frameworks and policy. There are several NGO and governmental climate change actors in Ethiopia. The country’s National Policy on Disaster Prevention and Management (NPDPM) was prepared in 1993. Ethiopia has also ratified the United Nations Framework Convention on Climate Change (UNFCCC) and under the mechanism, a National Adaptation Program of Action (NAPA) was produced in 2001 with an ambition to identify ‘immediate and urgent’ adaptation activities that address current and anticipated adverse effects of climate change and extreme climate events. The Environmental policy of Ethiopia indicates that environmental sustainability to be recognized in policies and strategies as a key prerequisite. In line with this the Environmental Protection Agency (EPA), was established and mainly assumes a regulatory role and coordinates various activities and included policy on climate change and pollution, particularly on promoting climate monitoring programs as the country is sensitive to changes in climate, identifying a firm and demonstrable commitment to the principle of containing climate change and fostering to use hydro, geothermal and solar energy to minimize an emission of greenhouse gases.

A prototype of the GMT FSM has been developed to acquire and to enhance the key technology – mirror fabrication and tiptilt actuation. The ellipsoidal off-axis mirror has been designed, analyzed, and fabricated from light-weighting to grinding, polishing, and figuring of the mirror surface. The mirror was tested by using an interferometer together with CGHs, which revealed the surface error of 13.7 nm rms in the diameter of 1030 mm. The SCOTS test was employed to independently validate the test results. It measured the surface error to be 17.4 nm rms in the diameter of 1010 mm. Both tests show the optical surface of the FSMP mirror within the required value of 20 nm rms surface error.

Newly hatched black porgy larvae (Acanthopagrus schlegeli) swam to the surface, with the mouth and anus still closed and were 1.90–2.11 mm (mean, 2.0 mm) in total length (TL). The larvae were 2.71–2.94 mm TL (mean, 2.82 mm) on day 2 after hatching. At this time, about two-thirds of the yolk was absorbed, the bladder and intestines had formed, and the mouth and anus were open. Total length was 4.32–4.66 mm (mean, 4.45 mm) at the post-larval stage on days 5–6 after hatching, and the yolk and oil globule were almost absorbed. The end of the notochord began to flex, and 6–8 caudal fin rays were visible. The larvae were 15.37–16.1 mm TL (mean, 15.83 mm) at the juvenile stage on days 30–32 after hatching, and the number of rays in all fins was completely revealed.

To successful molecular breeding, identification and functional characterization of breeding related genes and development of molecular breeding techniques using DNA markers are essential. Although the development of a useful marker is difficult in the aspect of time, cost and effort, many markers are being developed to be used in molecular breeding and developed markers have been used in many fields. Single nucleotide polymorphisms (SNPs) markers were widely used for genomic research and breeding, but has hardly been validated for screening functional genes in olive flounder. We identified single nucleotide polymorphisms (SNPs) from expressed sequence tag (EST) database in olive flounder; out of a total 4,327 ESTs, 693 contigs and 514 SNPs were detected in total EST, and these substitutions include 297 transitions and 217 transversions. As a result, 144 SNP markers were developed on the basis of 514 SNP to selection of useful gene region, and then applied to each of eight wild and culture olive flounder (total 16 samples). In our experimental result, only 32 markers had detected polymorphism in sample, also identified 21 transitions and 11 transversions, whereas indel was not detected in polymorphic SNPs. Heterozygosity of wild and cultured olive flounder using the 32 SNP markers is 0.34 and 0.29, respectively. In conclusion, we identified SNP and polymorphism in olive flounder using newly designed marker, it supports that developed markers are suitable for SNP detection and diversity analysis in olive flounder. The outcome of this study can be basic data for researches for immunity gene and characteristic with SNP.

The immune system in teleost fish is not completely developed during embryonic and larval stages, therefore effective innate mechanisms is very important for survival in such an environment. However, the knowledge of the development of immune system assumed to be restricted. In many species, lysozymes have been considered as important genes of the first line immune defense. The early detection of lysozyme mRNA in previous reports, led to the investigation of its presence in oocytes. As a result, c-type lysozyme mRNA transcripts were detected in unfertilized oocytes indicating maternal transfer. Therefore, we investigated the expression patterns of lysozymes in flounder, including the matured oocyte. In our results, c-type lysozyme mRNA was first detected in unfertilized oocyte stage, observed the significantly decreased until hatching stage, and was significantly increased after hatching stage. On the other hand, g-type lysozyme mRNA transcripts were first detected at late neurula stage, and the mRNA level was significantly increased after 20 dph. It may be suggest that maternally supplied mRNAs are selectively degraded prior to the activation of embryonic transcription. This study will be help in understanding the maturation and onset of humoral immunity during development of olive flounder immune system.

The egg development and early life history of Korean spotted sleeper, Odontobutis interrupta which is Korean endemic species from Sora-choen was investigated. The Korean spotted sleeper were caught at Sora-myeon, Yeosu-si, Jeollanamdo, from Korea at May in 2014. The fertilized eggs were 4.23 ± 0.05 mm in long diameter and had oil globules. Hatching time of the embryo began about 442 hr 14 min after fertilization under water temperature of 19.5oC. The newly hatched larvae were 4.27 ± 0.35 mm in total length and their anus were not yet opened. 3 days after hatching postlarvae was measured 6.20 ± 0.11 mm in total length. 10 days after hatching postlarvae was measured 6.69 ± 0.14 mm in total length.
