This study was conducted to investigate egg development and larvae morphological development of catfish and to provide basic data to clarify the genetic relationship with Siluriformes fish. The mother fish that was used in this study was caught in the stream of Nakdong River in Uiseong-gun, Gyeongbuk. The temperature range of the breeding was 23.0- 25.0℃ (mean 24.0±1.0℃) and egg size was 1.62-1.70 mm (mean 1.66±0.05, n=30). Eggs of catfish began hatching at 54 hours and 40 minutes after fertilization. Immediately after hatching, the total length of larvae was 3.60-3.65 mm (mean 3.62±0.03, n=5) and had an egg yolk without swimming ability. On the third day after hatching, the larvae at the medium stage was 8.00-8.65 mm (mean 8.32±0.45) in total length, and two pairs of whiskers formed around the mouth were elongated. On the 12th day after hatching, the larvae at the juvenile stage was 16.5-17.0 mm (mean 16.7±0.35) in total length, and the stem of each fin was in the range, and the juvenile at this period was morphologically similar to the mother fish.

Interferon-stimulated gene 15 (ISG15) is known to interfere with viral replication and infection by limiting the viral infection of cells. Interferon-stimulated gene 15 (ISG15) interferes with viral replication and infectivity by limiting viral infection in cells. It also plays an important role in the immune response. In this study, tissue-specific expression of ISG15 in healthy rock bream samples and spatial and temporal expression analysis of rock bream ISG15 (RbISG15) were performed following rock bream iridovirus (RSIV) infection. RbISG15 expression was significantly higher in the eye, gill, intestine, kidney, liver, muscle, spleen, and stomach, but low in the brain. There were particularly high levels of expression in the liver and muscle. RbISG15 expression was also examined in several tissues and at various times following RSIV infection. ISG15 expression increased within 3 h in the whole body and decreased at 24 h after infection. In addition, temporal expression of several tissues following RSIV infection showed a similar pattern in the muscle, kidney, and spleen, increasing at 3 h and decreasing at 72 h. These results suggest that ISG15 plays an important role in the immune response of rock bream. Overall, this study characterizes the response of RbISG15 following RSIV infection.

This study presents the application of satellite laser ranging (SLR) to orbit determination (OD) of high-Earth-orbit (HEO) satellites. Two HEO satellites are considered: the Quasi-Zenith Satellite-1 (QZS-1), a Japanese elliptical-inclinedgeosynchronous- orbit (EIGSO) satellite, and the Compass-G1, a Chinese geostationary-orbit (GEO) satellite. One week of normal point (NP) data were collected for each satellite to perform the OD based on the batch least-square process. Five SLR tracking stations successfully obtained 374 NPs for QZS-1 in eight days, whereas only two ground tracking stations could track Compass-G1, yielding 68 NPs in ten days. Two types of station bias estimation and a station data weighting strategy were utilized for the OD of QZS-1. The post-fit root-mean-square (RMS) residuals of the two week-long arcs were 11.98 cm and 10.77 cm when estimating the biases once in an arc (MBIAS). These residuals were decreased significantly to 2.40 cm and 3.60 cm by estimating the biases every pass (PBIAS). Then, the resultant OD precision was evaluated by the orbit overlap method, yielding three-dimensional errors of 55.013 m with MBIAS and 1.962 m with PBIAS for the overlap period of six days. For the OD of Compass-G1, no station weighting strategy was applied, and only MBIAS was utilized due to the lack of NPs. The post-fit RMS residuals of OD were 8.81 cm and 12.00 cm with 49 NPs and 47 NPs, respectively, and the corresponding threedimensional orbit overlap error for four days was 160.564 m. These results indicate that the amount of SLR tracking data is critical for obtaining precise OD of HEO satellites using SLR because additional parameters, such as station bias, are available for estimation with sufficient tracking data. Furthermore, the stand-alone SLR-based orbit solution is consistently attainable for HEO satellites if a target satellite is continuously trackable for a specific period.

Acute myocardial infarction (AMI) as an acute form and a catastrophic manifestation of coronary artery disease (CAD) is the major cause of morbidity and mortality worldwide. The prevalence and incidence of myocardial infarction can be influenced by demographic, biological and psychosocial factors, and it is rare in childhood and adolescent years. Contrary to the elderly, where cardiac attack is mainly caused by CAD, exercise-induced cardiac attack is relatively more prevalent in a young adult. We report here on a case of ST-segment elevation myocardial infarction (STEMI) in a young adult during vigorous physical activity and we review the relevant literatures.

This study selected commonly known species of fruit trees, and re-selected the species that endure the stress of extreme cold weather and physiologically restore themselves to the previous state until the following year. Then we could go ahead to propose the species that were appropriate as urban greening plants in weather condition of any part of the country. To do this, we conducted an experiments for six species of fruit trees based on the preference of the general public and recommendation of the experts; Morus alba (English name: mulberries), Diospyros kaki (English name: Persimmon), Prunus persia (English name: Peach), Elaeagnus umbellata var. coreana (English name: Korean Autumn Olive), Malus domestica 'Alps Otome' (English name: Alps Otome), and Prunus mume (English name: Blue Plum). The experiment verifies whether the trees survive without any stress from the cold weather under the national climate conditions (one in the suburbs of Seoul: Yongin city, one in the central Chungcheong region: Daejeon city, and in the southern Gyeongsang region: Jinju city in Korea). The experiment lasted for a year from August 2016 to August 2017. The levels of electrolytic efflux, chlorophyll content, plant height, fresh weight, and dry weight were measured four times (on August of 2016, January, February, and August of 2017) for each tree planted bare ground outdoors. Results showed that Diospyros kaki, Prunus persia, and Malus domestica 'Alps Otome' were proven durable and resistant to winters of all three areas (one in the suburbs of Seoul: Yongin city, one in the central Chungcheong region: Daejeon city, and in the southern Gyeongsang region: Jinju city in Korea). Especially, the increase of chlorophyll content and the reduction of electrolytic efflux were noticeable in Prunus persia than in the other two species, proving itself as the most cold-tolerant among the six species used in the experiment. In addition, interpreting from the physiological restoration data of one-year span before and after getting through winterer, Prunus persia was proven to be the most cold-tolerant species.

This study aimed to understand the distribution of vegetation in the eastern and western sides of the Baekdudaegan (ridge) dividing the Odaesan National Park, as influenced by its topography and climate. The actual vegetation, topography and climate for each side were used in the overlay analysis. The results of the analysis of actual vegetation showed a high distribution rate of Quercus mongolica forest on both the eastern and western sides. On the eastern side, the distribution rate of Pinus densiflora forest and P. densiflora-Q. variabilis forest was high, while the western side had a high distribution rate of deciduous broad-leaved tree forest and Abies hollophylla forest. A clear trend was identified for vegetation distribution with respect to elevation but not with respect to slope or aspect. The results of micro-landform analysis showed that the P. densiflora forests in the ridge and slope and the deciduous broad-leaved tree forest in the valley were respectively distributed with a high ratio. In terms of climate, the eastern side revealed an oceanic climate, with a relatively high average annual temperature, while the western side was characterized by relatively high average annual humidity and average annual precipitation. The distribution rate of P. densiflora forest was found to be high on the eastern side of the mountain range.

This study investigated the effect of leaf form or phenotype and light intensity on the toluene, xylene, and ethylbenzene removal of three foliage plants. Green and variegated forms of Ardisia pusilla, Scindapsus aureus, and Hedera helix plants were grown under 10 and 20 μmol･m-2･s-1 light intensities for 8 months and were tested for their volatile organic compound (VOC) removal efficiency for 15 h. In general, variegated forms of the plant species have higher VOC removal after 15 h of VOC exposure than green plants, particularly when grown in 10 μmol･m-2･s-1. This is more evident in A. pusilla and S. aureus than in H. helix. The highest rate of toluene, m-, p-, and o-xylene removal per hour by plants grown under 10 μmol･m-2･s-1 was achieved by variegated A. pusilla, while for ethylbenzene, variegated A. pusilla and variegated H. helix had the highest removal rate per hour. In plants grown in 20 μmol･m-2･s-1 light intensity, variegated and green H. helix have the highest removal rate per hour of toluene and m-, p-, and o-xylene. For ethylbenzene, variegated A. pusilla and green and variegated H. helix had the highest removal rates per hour. The plant with the lowest removal rate per hour for all five VOCs was green S. aureus grown under both light intensities. The percentage VOC removal rate of variegated over green plants was 22% higher at a lower light intensity

This study was carried out to examine the effective wet harvesting solution for development of wet distribution system in standard chrysanthemum (Dendranthema grandiflorum) ‘Baekma’. The cut flowers were treated immediately in floral preservative solutions or dry condition after harvesting, and then the effects on quality of cut flower were compared. Also, we investigated the effects of NaOCl and sucrose on vase life and quality of cut flower. When the cut flowers were treated immediately in tap water, Chrysal OVB, Floralife, Hiflora solutions after harvesting, flower diameter and fresh weight of cut flower increased compared to dry condition treatment. In single treatment of 100 mg･L-1 NaOCl as wet harvesting solution, flower diameter and fresh weight of cut flower increased more than other treatments, and vase life was prolonged to 1.5 days than control. But, flower diameter and fresh weight of cut flower decreased in 0 or 200 mg･L-1 NaOCl. When the cut flowers were treated in combination solution of 100 mg･L-1 NaOCl and 0.1% sucrose, the flower diameter was the largest by 9.8 cm, and fresh weight of cut flower was maintained the highest in holding solution. On the other hand, flower diameter and fresh weight of cut flower were lowest in combination solution of 100 mg･L-1 NaOCl and 2.5% sucrose. There was no difference in vase life between treatments mixed with NaOCl and sucrose. Therefore, it was suggested that treatment mixed with 100 mg･L-1 NaOCl and 0.1% sucrose as wet harvesting solution was the most effective for vase life and quality of cut flower in standard chrysanthemum ‘Baekma’.

This study was conducted to investigate the effects of rooting promoters on rooting and seedling quality in Buddleja davidii ‘Empire Blue’, Hydrangea paniculata ‘Magical Candle’, Hydrangea arborescence ‘Annabelle’, Stephanandra incisa semi-hardwood cuttings. IAA and IBA (500, 1000, or 1500 mg･L-1 soaking for 30 minutes and 3,000 mg･L-1 dipping for 10 seconds) or RootoneTM were used as rooting promoter. In B. davidii ‘Empire Blue’, IBA 1,500 mg･L-1 soaking reduced rooting percentage than control, but the effect of rooting promoters was generally insignificant. Number of leaves and shoot length were reduced in RootoneTM and IBA 1,500, 3,000 mg･L-1 treatments. IAA 1,000~3,000 mg･L-1 and IBA 500 mg･L-1 treatments showed better mat formation than control. The rooting ratio of H. paniculata ‘Magical Candle’ increased to 66.7% in IBA 1,500 mg･L-1 soaking treatment compared with 26.4% in the control. The mat formation was higher in RootoneTM, IAA and IBA treatments compared to control, and root length showed longer tendency in IAA and IBA except RootoneTM. The rooting ratio of H. arborescence ‘Annabelle’ was highest at 70.8% in the control and auxin treatments showed negative effect on the rooting percentage except IAA 1,000 mg･L-1 soaking treatment. The mat formation was very poor in IBA 1,000 and 1,500 mg･L-1 soaking at 1.1 and 1.3, respectively. S. incisa showed high rooting percentage at RootoneTM (80%) and IAA 1,500 mg･L-1 (80%) treatments compared to control (51.7%). Root length and dry weight were high in IAA 1,500 mg･L-1 soaking treatment. As a result, B. davidii ‘Empire Blue’ and H. arborescence ‘Annabelle’ did not need rooting promoter for stem cuttings, and IBA 1,500 mg･L-1, IAA 1,500 mg･L-1 soaking treaments could be used to improve rooting and seedling quality of H. paniculata ‘Magical Candle’ and S. incisa semi-hardwood cuttings, respectively.

The purpose of this research is to examine reasons and evaluate strategies implemented by the Indian banking industry in tackling jaycustomers in general and in light of the recent demonetization in particular. After a thorough germane literature and theoretical framework on jay-customers and Indian banking industry, researchers framed a well-structured questionnaire for collecting banking employees opinions along with a set of questions framed to conduct in-depth personal interviews with banking customers. The collected data were summarized, coded, and controlled by using Software R and the selected hypotheses were analyzed by the observance of percentile values. More than 90 percent of banking employees said lack of proper supply of cash from the Reserve Bank of India is the major reason for this kind of customer behaviour and shockingly 95 percent of banking customers expressed backdoor preference given by banking employees to some big customers is the major reason. The research confined only two state capitals Amaravati and Bangalore in India and covered only two largest banks one in public and private sector. The research provides useful insight into the crucial reasons for jay-customers’ behaviour from the dyadic perspective of both employees and customers of the Indian banking industry.

Purpose - The paper aims to explore the critical and uncover issues encountered to the supply-chain companies in launching halal based services in India. Research design, data, and methodology - After a meticulous review of relevant literature on the halal concept and halal logistics, researchers involved in a data collection by conducting semi-structured focus group interviews. Four groups with a maximum of 5 members each have chosen from the areas of transportation, warehousing, certification, and packaging. A total of 20 questionnaires were collected by applying purposive sampling method. Results - More than 95 percent of the chosen focus groups agreed that they know only about halal but don’t have any exposure to halal logistics. The discussion has revealed that the adoption rate for halal transportation, warehousing, halal certification, and packaging is almost zero. The respondents were chosen only from transportation, warehousing, certification and packaging companies from south India which are operating throughout India. This research never attempts to be acquainted with the opinions of channel members who directly or indirectly involved in meeting customer demands. Conclusions - This is a ground-breaking effort aimed to study the critical issues related to Indian halal logistics which is beneficial to both logistic companies as well as to the academic world.

The Northern States of Malaysia comprises of four states (Penang, Kedah, Perlis and Perak) still record high poverty incidence eventhough Malaysia has experienced a remarkable reduction of poverty over the past century. Economic activities in Perlis and Kedah that are predominantly agriculture in the rural area contribute to this disparity. To add, rural households are also subject to risks and uncertainties that make them more vulnerable to poverty. This study examines the impact of risks and assets on households’ vulnerability to poverty. A survey of 400 respondents was conducted in December 2015 in the northern region of Malaysia. From these 400 questionnaires, only 298 were considered valid and used in the analysis. Using a logistic probability function, the results indicated that risks are not a significant threat to households. Gender and strata are crucial elements that significantly determine households’ vulnerability. While human capital and financial capital significantly reduce households’ vulnerability to poverty, physical and natural capitals were not statistically significant. The study suggests that the government and practitioners design strategies and policies with an assets-based approach. The asset-based approach is more appropriate for linking the causes of poverty to vulnerability.

This study aims to propose an assessment tool of port service quality (PSQ) in the context of container transport logistics (CTLs), by taking the perspectives from port users. The CTLs defined in this study are the relevant activities of serving the physical flows of a container box from a point of origin via a container port to a point of destination. To address the ports’ role in collaboration between its channel members in CTLs, the PSQ measures for all port user groups (i.e. common PSQ measures) are selected based on the relevant CTLs activities involved by port, and its users within terminal/port area as well as throughout the CTLs chain. An importance-performance analysis (IPA) is applied as a diagnostic tool to analyse the status quo of Busan Port in CTLs contexts, by comparing the importance and performance (IP) scores against each individual CTLs criterion. The findings from the IPA reveal that port managers and policy makers at the Busan Port should concentrate on six PSQ measures (i.e. SR1, SR4, ITS1, VAS1, VAS4, ICI3) to enhance PSQ in CTLs. However, four measures (i.e. ITS2, ITS3, ITS4, VAS2) are identified as a possible overkill, indicating an area of inefficiency where a remedial action of the cost-cutting decision is necessary. On the other hand, the Busan port shows an outstanding performance on four measures such as SR2, SR3, ICI1 and ICI2. The measures are not only important but also high performance. The study findings provide managerial guidance to port managers in Busan Port, in view of searching for managerial and operational strategies for sustainable port growth.

본 연구에서는 조석의 영향을 주기적으로 받는 임진강 하류부의 계획홍수위를 보다 합리적으로 산정하는 방안을 검토해 보았다. 우선 감조하천의 특성을 감안할 수 있는 부정류모의를 수행하여 홍수위의 변동을 살펴보았고, 수위 계산에 민감한 매개변수인 조도계수를 해당지역의 특성에 맞게 현실화하여 홍수위 변화를 분석하였다. 그 결과를 2011년 임진강하천기본계획보고서에서 고시한 임진강 하구 계획홍수위와 비교하고, 감조구간에서 홍수위 산정시 유의해야 할 점들을 정리하였다. 참고로 2011년에 고시된 계획홍수위는 대규모 하상 준설 단면을 입력자료로 하여 부등류모의를 통해 산정된 바 있다. 본 연구의 결과, 임진강 하구의 경우 홍수위 산정에 있어서 조도계수를 한강하구와 동일한 값으로 할당하고, 하구 조위를 감안할 수 있는 부정류 모의를 수행하면 하상 준설을 하지 않더라도 홍수위가 제방 여유고를 만족함을 알 수 있었다.

While adipose-derived stem cell-conditioned medium (ADSC-CM) has been demonstrated to promote skin wound healing, the mechanism regulating this effect remains unelucidated. In this study, we aimed to investigate the role of Ell3 in the wound healing activity of ADSC-CM. In vitro analysis revealed that Ell3 suppression in ADSCs impairs the promotive activity of ADSC-CM on the proliferation and migration of mouse embryonic fibroblasts (MEF) and normal human dermal fibroblasts (NHDF). Consistently, the expression of MMP family genes, which regulate cell proliferation and migration, was significantly suppressed in MEF and NHDF treated with siEll3-transfected ADSC-CM. Proinflammatory cytokines, such as interleukin-1 and interleukin-6, were highly expressed in MEF treated with siEll3-transfected ADSC-CM. The wound healing activity of siEll3-transfected ADSC-CM was significantly lower than that of the control in vivo. Our results suggest that Ell3 may contribute to the inhibition of inflammatory response during skin wound healing.
