Efficient yet realistic ship routing is critical for reducing fuel consumption and greenhouse-gas emissions. However, conventional weather-routing algorithms often produce mathematically optimal routes that conflict with the paths mariners use. This study presents a hybrid approach that constrains physics-based weather routing within an AISderived maritime traffic network (MTN) built from one year of global Automatic Identification System data. The MTN represents common sea lanes as a graph of approximately 10,956 waypoints (nodes) and 17,561 directed edges. Using this network, an optimal low-emission route is computed via graph search and then compared against both a traditional unconstrained route and an advanced weather-routing model (VISIR-2). In a May transitionseason case (Busan–Singapore voyage), the AIS-constrained route reduced fuel consumption and CO₂ emissions by about 1.9% relative to the fastest feasible route, while closely following real traffic corridors (over 90% overlap with actual 2024 AIS tracks). While this 1.9% saving does not reach the high-end potential of an unconstrained, state-of-the-art model like VISIR-2 (which can demonstrate double-digit savings in certain conditions), it is achieved with an increase in transit time of ~6.5 h (≈3.2%). This represents a crucial trade-off, prioritizing operational realism and adherence to real-world traffic corridors over maximum theoretical efficiency.

Air conditioner filters purify the air of indoor environments by removing air pollutants and supporting the efficiency of the unit’s cooling function. However, an air conditioner filter can become a microenvironment in which some fungi can grow as dust continues to accumulate and favorable humidity conditions are formed. Fungal growth in air conditioner filters could lead to fungal allergies or fungal diseases, in addition to emitting a foul odor. In an effort to understand what species causes this malodorous problem, we investigated the diversity of fungi found in air conditioners. Fungi were sampled from the collected air conditioner filters and grown on DG18 agar media. After purification for pure isolates, species identification was undertaken. Colony morphology was observed on PDA, MEA, CYA, and OA media. Microstructures of fruiting body, mycelia, and spores were examined using a light microscope. Molecular identification was performed by PCR and sequencing of PCR amplicons, and molecular phylogenetic analysis of sequenced DNA markers, including the Internal Transcribed Spacer (ITS), the 28S large subunit of the nuclear ribosomal RNA (LSU rDNA), the β-tubulin (BenA) gene, the Calmodulin (CaM) gene, and the DNA-directed RNA polymerase II subunit 2 (RPB2) gene. Through this identification process, we found two fungal species, Aspergillus miraensis and Dichotomopilus ramosissimus, which are unrecorded species in Korea. We will now report their morphological and molecular features.

Cryopreservation of bovine embryos is used to efficiently implant surrogate mothers. It has been widely accepted that high lipid content in the oocyte interrupts its survival during freeze-thaw cycles. Serum component in the culture medium is thought to increase the embryo`s lipid contents. Conversely, L-carnitine stimulates lipid metabolism by transporting long chain fatty acids into the mitochondria. Objective of this study was to analyze the effect of L-carnitine supplementation in IVM medium and defined IVC medium on the development, lipid contents and the cryosurvival of bovine IVF embryos. 0.0, 1.5, 3.0 and 6.0 mM L-carnitine was supplemented in IVM medium, respectively (IVM-LC 0.0, LC 1.5, LC 3.0 and LC 6.0). Development rate from the 2cell to the morula stages was higher in IVM-LC 3.0 groups than those of IVM-LC 6.0 (p<0.05). But there were no significant differences among the other groups in the blastocyst rates and lipid content results. When 0.0, 1.5, 3.0 and 6.0 mM L-carnitine were supplemented in IVC medium (IVC-LC 0.0, LC 1.5, LC 3.0 and LC 6.0), development competence was not significantly different between those embryos. Lipid contents of embryos treated L-carnitine (IVC-LC 1.5, 3.0 and 6.0) were significantly lower than embryos of non-treated group. L-carnitine was supplemented 0.0, 1.5, 3.0, 6.0 mM during IVM and 3.0 mM during IVC (LC 0.0 - 3.0, LC 1.5 – 3.0, LC 3.0 – 3.0, LC 6.0 – 3.0) and cryosurvival of blastocysts confirmed after freezing-thawing. There were no significant differences on development, but LC 3.0 – 3.0 was significantly lower lipid contents than other groups. And LC 3.0 – 3.0 had better survival rates and hatched rates of blastocysts than LC 0.0 – 0.0. In conclusion, supplementation of L-carnitine in defined IVC medium decreases lipid contents. And L-carnitine supplementation improves cryosurvival and developmental ability of bovine IVF embryos.

The early-onset familial Alzheimer's disease (EOFAD/ FAD), the less common type of Alzheimer's disease (AD) currently affects a vast number of individuals worldwide. This type is being inherited as an autosomal dominant fashion. Missense mutations on Amyloid precursor protein (APP) and Presenilins 1 and 2 (PSEN1 & PSEN2) are known as major genetic factors in FAD. Conversely, missense mutations on microtubule-associated protein tau (MAPT) are also thought to involve. Up to date, several triple-transgenic animal models with muted forms of the human APP, PSENs and MAPT have been reported. Compared to other animals, canines are more emotional and their disease signs can be easily diagnosed. This attempt was to develop a triple transgenic canine model for the AD. We have obtained the coding sequences of APP, PSEN1 and MAPT from Dana-Farber/Harvard Cancer Center DNA resource core at HMS and incorporated several common AD mutations. The transgenic construct is composed of hNSE (ENO2) promoter-driven three AD genes fused together with modified 2A sequences. It was transfected into the canine fetal fibroblasts which were then used to perform somatic cell nuclear transfer (SCNT). The viable transgenic embryos were obtained after in vitro culture and the GFP was detected. In this study, we have successfully produced viable triple transgenic canine cloned embryos using SCNT technique. These transgenic canine embryos will be further developed into canines with FAD. The transgenic canines will be a good candidate in the AD research field.

The infrastructure that man absolutely needs creates a lot of environmental load. The environmental load is quantified global environment pollution. So we can use LCA method for assess and control environmental load. In this study, we developed the environmental load estimating model to evaluate quickly in design stage when maintaining infrastructures facilities. Especially, we chose NATM tunnel because it is economical and there are many example of construction on public roads and expressway. First, we made a list of the breakdown cost by using collected unit cost of Korea Expressway Corporation and Seoul-Si about tunnel maintenance. So we chose major work classification. We selected the major classification such as pavement repairing inside tunnel, leaked surface treatment of tunnel, attached tile repairing inside tunnel and tunnel cleaning etc. We excluded concrete repairing because it is not easy to define maintenance factor about concrete repairing. Next, we made data bases of standard supply and resources need by specialist work classification. Using data bases, we was able to estimate environmental load by designating an input variable such as lane, pavement, length, tile repairing, leaked surface treatment and cleaning method. Lastly, we made environmental load estimating model after it is verified by comparing the results with the actual environmental load and estimated environmental load. Finally, our goal of this study is to develop the methodology that easily estimates the environmental load. Accordingly, the environmental load will be decreased by using this model in stage of planning, design and maintenance. Also, it is expected that the maintenance management estimating model developed from this study will be possible to do eco-friendly management of the road and tunnel construction.

Nanoemulsions are actively used in several applications for pharmaceutical, cosmetic and chemical industries. In this study, we propose the use of microfluidizer known as high pressure homogenizer to prepare lipid nanoemulsion as a potent cosmetic delivery carrier. The lipid nanoemulsions were prepared by O/W emulsion with hydrogenated lecithin and different type of oils. Effects of oil type on the stability of the lipid nanoemulsion were investigated with Dynamic Light Scattering (DLS) and Zeta-potential. Arbutin was used as model drug for transdermal administration through hairless mouse skin. Transdermal arbutin delivery using the lipid nanoemulsions was studied with HPLC method.

현재 인간이 일반적으로 이용하는 의료용 단백질은 대개 동물세포 배양기술에 의하여 생산되고 있다. 그러나 제한된 특정 시설에서 생산되기 때문에 생산 단가가 높아서 전세계의 수요가 증가함에도 불구하고 일반화하는 데는 한계가 있는 실정이다. 이러한 문제를 극복하기 위하여 오래전부터 식물시스템을 이용하여 의료용 단백질을 생산하는 연구가 관심을 끌고 있다. 즉 쉽게 규모화할 수 있고 생산비용 효과도 경제적이고 동물세포보다 더 안전하게 의료용 단백질 생산할 수 있는 수단이 될 수 있기 때문이다. 이를 위하여 식물에 안정적으로 유전자를 핵 게놈과 엽록체 게놈에 형질전환 시키는 기술과 바이러스 운반체를 이용하여 일시적 발현을 유도함으로 의료용 단백질을 생산하는 기술이 개발되고 있다. 최근 해체 바이러스 기반의 운반체 개발은 재조합 단백질을 빠르고 일시적 발현으로 대량생산을 가능하게 하고 있다. 따라서 이 바이러스 발현시스템이 적절한 식물기반의 대량생산을 위한 플렛폼을 제공하고 있다. 따라서 본 총설은 식물로부터 의료용 단백질을 생산하는데 있어서 식물 바이러스발현 시스템 개발 및 이용에 대하여 기술하였다.

Articles in one domestic journal, English Teaching (ET), and one international journal, TESOL Quarterly (TQ) from 2011 to 2013 were surveyed in order to analyze current research trends and to suggest better orientation toward future research focusing on participants, research methods, target language skills, and research topics. The results show that university students have participated most in both of the journal articles, indicating that they are practically available to the researchers in higher educational settings. The proportion of quantitative and qualitative research methods was well balanced in TQ, while, in ET, more than 50 percent of the articles relied on quantitative research methodology along with a relatively larger proportion of mixed method research in ET. In terms of target language skills, writing has been studied most in ET and speaking in TQ, showing growing interest in productive language skills nowadays. As for research topics, articles based on socio-cultural factors have been published most in TQ and articles based on classrooms pedagogy in ET, which reflects that English learning is performed mostly in classroom settings in Korea. Pedagogical implications and suggestions are made based on the findings

The legume family (Fabaceae) is the third largest family of flowering plants worldwide and often damaged by stink bugs, particularly Riptortus clavatus Thunberg (Heteroptera: Alydidae). This insect selectively feeds and oviposits on these plants, resulting in >50% of damage to soybeans harvested in autumn. The most common control methods for this insect are periodic application of chemical pesticides, pheromone traps, and bait crops, but still they encounters residual problem, insect resistance or low control efficacy. The current management system needs alternative control methods, which possibly combined with the present methods. Some entomopathogenic fungi have high virulence against the nymphs and adults of R. clavatus in a favorable conditions, reaching ∼80% mortality with mycosis in 3∼5 days. The genera of Beauveria and Metarhizium are possible control agents for effective and safe management of the serious pest. Fungal infection in R. clavatus was observed using an egfp-expressing fungal transformant. Thermotolerant entomopathogenic fungal conidia can be produced in cereal substrates, which enables conidia to be stable for long times. Our considerations need to be given to the combinations with other control methods, such as chemical pesticides or pheromone trap.

The purpose of this study is to provide the case of influence of myofacial release(MFR) and cryotherapy in acute whiplash injury. The subjects were consisted of 3 adults(2 males, 1 female) who had been diagnosed with whiplash injury. The performance period was 1 weeks, 6 times and 1 time is 40min(MFR: 20min, cryotherapy: 20min). We measured neck pain(Visual analogue scale, VAS) and cervical alignment(cervical curvature & line of gravity). All measurements of each subject were measured at pre-treatment and post-treatment. The results are listed below. The neck pain(VAS) index decreased from 7.54cm to 4.11cm. The cervical curvature increased from 23.62°to 29.76°. The line of gravity decreased from 8.03mm to 3.66mm. Based on the results, it can be suggested that both MFR and cryotherapy can be used to neck pain and alignment in acute whiplash injury.

The anti-proliferative efficacy of t,t-conjugated linoleic acid (t,t-CLA), c9,t11-CLA, and t10,c12-CLA was compared in several human cancer cell lines. Gastric NCI-N87, liver Hep3B, pancreas Capan-2, and lung NCI-H522 cancer cells were incubated with 50 μM CLA isomers over a period of 6 days. The t,t-CLA inhibited the growth of all cancer cell lines to different extents, but c9,t11-CLA and t10,c12-CLA inhibited or stimulated the growth of the cancer cell lines. NCI-N87 cells were the most sensitive to growth inhibition and apoptosis from all CLA isomers tested. In NCI-N87 cells, CLA isomers reduced the release of arachidonic acid (AA) via the inhibition of cytosolic phospholipase A2 (cPLA2 ) activity, consequently reducing the production of PGE2 through the inhibition of cyclooxygenase-2 (COX-2). The efficacies of CLA isomers were in the following order (from most to least effective): t,t-CLA, t10,c12-CLA and c9,t11-CLA. Overall, these results imply that the anti-proliferative efficacy of t,t-CLA on cancer cells, especially NCI-N87 cells, was greater than other CLA isomers due to its induction of apoptosis through the inhibition of cPLA2 and COX-2 activities.

Experts of medicine, philosophy and psychology found that human somatotypes were related to personality or physical characteristics and classified somatotypes into various forms. This study explored the changes and types of somatotyping methods from Before Christ to present day and identified the status of studies of somatotypes in the area of physical therapy. This study covered the methods applied in various majors with a focus on those provided in books and papers of Heath BH. and Carter JEL. Based on the results, there are officially twelve assessment methods. Currently, the method of Heath & Carter is most widely applied. Somatotypes are studied in many areas. It is actively explored in the area of pain physical therapy, thermotherapy and integumentary physical therapy. Also, the soft tissue physical therapy area seeks interdisciplinary studies. This study found that there were various assessment methods in diverse areas. It is likely that continuous studies will develop new assessment methods. It is hoped that in the area of physical therapy, somatotypes shall be applied more amply.

The purpose of this study is to analyze the correlation between the stature and the muscle performance ratings and the subjective discomfort rations at performing lower arm's pronation and supination according to change sin the height of working table for more efficient performance at designing a working table and performing a work. For the purpose, this study conducted an experiment targeting 40 people in their 20s, who were classified into 4 groups each group composing 10 people at intervals of 5cm from the standard stature of 166.5cm. The experiment measured the maximum isometric pronation and the supination muscular power, and at measuring the factors, the heights of working tables were set as 800mm, 850mm, and 900mm. From the measurement results, it was found that the stature and the maximum muscular power was correlated. That is, as the experiment groups's average stature is higher, the maximum muscular power was higher. For the correlation between the motion patterns(pronation and supination) and the maximum muscular power, it was seen that the maximum muscular power was higher at performing the pronation than the supination. In the correlation between motion patterns and the subjective discomfort ratings, it was seen that the subjective discomfort rating was higher at performing the supination than the pronation. For the correlation between height adjustment and the subjective discomfort ratings, as the height of working table was lower, the subject discomfort rating was lower. Therefore there was no difference in the maximum muscular power according to the height changes of working table, but it was found that as the working table was higher, the user felt more comfortable.

For reconstituting genetic resource(Korean Native Chicken: KNC) with grem-line chimeric chicken made with cryopreserved biastdermal cells, the experiments were carried out to optimize cryopreservating conditions. Stage X biastdemal cells were collected from KNC embryos and dissociated. Cells were susupended in medium containing cyopretectant and fetal bovine serum(FBS), and distributed into plastic ampules. Cell susupensions were seeded to induce ice formation at — 7℃ to — 35℃ at in the experiments, the effect of modification of dissociation way, concentration of FBS and cell density on the vaibility of frezen-thawed cells were investigated by trypan blue exclusion. Then change the way of cell dissociation from pipetting to short time vortexing, viability of frozen- thawed cell tended to be increaced from 29 % to 52 %. Increase concentraition of FBS in frozen medium from 20 % to 80 % made viability of thawed cell from 28 % to 35 %. The viability of thawed cells were 33.9% frozen at 2 embryos/ 0.5 ml, and 43.6 % frozen at 20embryos/0.5 ml. Furthermore, combination of three modifications make big improvement. The viability of frozen-thawed cell was 60 % for combinated method, and 41 % for general method. This result means the advance to practical cryoreservation of blastdermal cell of the KNC(Ogolgye breed).
