  • The purpose of this study was to evaluate survival rates of vitrified mouse blastocysts in various vitrification solutions (cryoprotectants) and apparatuses. The mouse blastocysts were harvested from culture of mouse 2 cell embryo and were divided into three group (i) untreated (control); (ii) exposed to cryoprotectant agents; or (iii) cryopreserved by various vitrification apparatuses. Vitrification solutions are 40% ethylene glycol (EG) + 5.8 mg/mL ficoll + 0.5M sucrose (EFS solution), 3M glycerol + 3M EG (ES solution), 20% EG + 20% dimethyl sulfoxide (ED solution), 3M EG + 1.0 m sucrose (ES solution). Vitrification apparatuses consisted of 5 groups ; closed plastic straw (CPS), electron microscope (EM) grid, cryoloop, open pulled straw (OPS), and glass micropippete in plastic straw (GPS). The survival rates of control were 88.0%. The survival rates of exposed blastocysts in EFS, GE, ED, and ES solutions were 70.8%, 43.5% (P<0.01), 83.3% and 65.2%, respectively. The survival rates of vitrified blastocysts in CPS, EM grid, cryoloop, OPS and GPS were 56.5% (P< 0.01), 72.7%, 83.3%, 60.9% (P<0.05) and 54.2% (P<0.01), respectively. Among the vitrification solutions, the highest survival rate was seen in blastocysts vitrified in EG + DMSO (83.3%). The survival rate was not significantly different from that of the control (88%). Blastocysts cryopreserved with glycerol in all groups had an overall low survival rate of 43.5%. Survival rate of mouse blastocysts between vitrification apparatuses showed higher in cryoloop.

  • Background: The relationship between risk factors and likelihood of occupational injury has been studied. However, what has been published has only provided a limited explanation of why some of the employees working in the same environment as other employees suffered a single-injury event, while other employees experienced multiple-injury events. This article reports on an investigation of whether artisanal and small-scale miners in Migori County of Kenya are susceptible to a single-injury or multiple-injury incidences, and if so, what underpinning parameters explain the differences between the single incident injured and the multiple incident injured group. Mine management commitment to safety in artisanal and small-scale mining (ASM) operations is also considered. Materials and methods: The research objectives were achieved by surveying 162 uninjured and 74 injured miners. A structured, closed-end questionnaire was administered to participants after the stratification of the study population and systematic selection of the representative samples. Results: The results showed that most injured miners suffer a single-injury incident rather than experiencing multiple-injury events, and laceration (28.40%) was the common injury suffered by the miners. The analysis showed that the risk factors for the single incident injured group were not similar to those in the multiple incident injured group. The research also found mine workers have low opinion about mine management/owners commitment to safety. Conclusion: The study concluded that mine management and miners need to be educated and sensitized on the dangers of this operation. Provision of safety gears and positive safety culture must be a top priority for management.

  • A study was conducted to investigate the effect of water temperature and photoperiod on the oxygen consumption of the fasting juvenile Pacific cod Gadus macrocephalus (mean body weight 79.9${\pm}$2.0 g) in order to quantify metabolic response of the species under given conditions. The oxygen consumption rate (OCR) of G. macrocephalus was measured under a combination of four different water temperatures (7, 10, 13 and $16^{\circ}C$) and three different photoperiods (24L:0D, 12L:12D and 0L:24D) with an interval of 5 minutes over a 24-hour period using a closed recirculating respirometer. Three replicates were set up in each treatment. OCRs increased with increased water temperatures under all photoperiod conditions (P<0.001). Mean OCRs at 7, 10, 13 and 16oC ranged from 793.7~1108.4, 1145.7~1570.3, 1352.8~1742.5 and 1458.2~1818.6 mg $O_2$ $kg^{-1}$ $h^{-1}$, respectively. Under all water temperature conditions except $7^{\circ}C$ (P<0.001), mean OCRs of G. macrocephalus were the highest in continuous light (24L:0D) followed by 12L:12D and 0L:24D photoperiods. Mean OCRs of fish exposed to the 12L:12D photoperiod were significantly higher during the light phase than during the dark phase under all temperature conditions (P<0.001). $Q_{10}$ values ranged from 3.19~5.13 between 7 and $10^{\circ}C$, 1.41~1.74 between 10 and $13^{\circ}C$ and 1.15~1.35 between 13 and $16^{\circ}C$, respectively. Based on overall results, water temperature, photoperiod and their combinations exerted a significant influence on the metabolic rate of juvenile cod. This study provides empirical data for estimating the amount of oxygen demand and managing the culture of cod under the given water temperatures and photoperiods.

  • 순환식 펄라이트 재배에서 오이의 양액흡수는 일사량 변화와 관계없이 단위 일사량당 흡수량이 80-100mgㆍMJ$^{-1}$까지 증가 후 일정하게 유지되어 양액흡수 지표는 전체 양액흡수량보다 단위일사량당 양액흡수량이 더 적합하였다(Fig. 1). 오이의 엽장$\times$엽폭 수치와 실측 엽면적과의 관계는 Y=-16.87+0.987x+5E-5x$^2$의 회귀식을 구할 수 있었으며 $r^2$=0.89의 높은 정의 상관을 보였다. NO$_3$$^{-}$ -N의 흡수량은 초기에 3mgㆍMJ$^{-1}$에서 후기 16mgㆍMJ$^{-1}$로 상승하였고 Ca는 초기에 3mgㆍMJ$^{-1}$에서 후기에 14mgㆍMJ$^{-1}$로, Mg는 초기에 1mgㆍMJ$^{-1}$에서 후기에 5mgㆍMJ$^{-1}$로 증가되었으나, 정식 후 62일 이후의 증가세가 둔화되었다. K는 초기에 5.0mgㆍMJ$^{-1}$에서 후기 18mgㆍMJ$^{-1}$로 증가되었으나 지속적인 증가를 보여주지 못하였는데 이것은 오이의 하엽 제거로 인한 결과로 생각되어진다. 그러나 P는 초기에 0.5mgㆍMJ$^{-1}$에서 후기에 3.2mgㆍMJ$^{-1}$로 지속적으로 증가되었다. S는 초기에 0.5mgㆍMJ$^{-1}$에서 중기에 6.5mgㆍMJ$^{-1}$까지 증가되다가 후기에 2.7mgㆍMJ$^{-1}$로 감소되었다(Fig. 2). 오이의 각각의 무기이온 흡수량과 가장 상관이 높았던 요소는 정식일수와 엽면적이었으며 이 두 요소와 단위일사량당 양액흡수량과는 $r^2$=0.92, 0.97로 높은 상관을 보였다(Table 1). 단위일사량당 양액흡수량을 이용한 각각의 무기이온 흡수량 회귀식은 $r^2$=0.8 이상으로 높은 상관관계를 보여 실용적 이용이 가능할 것으로 보였다(Fig. 3).

  • A patient with post-pneumonectomy empyema was treated sucessfully by modification of Clagett's operation after closure of bronchopleural fistula using a transsternal, transpericardial approach. His primary disease was pulmonary tuberculosis, and he had a past history of left upper lobe lobectomy 34 year ago. Recently recurred pulmonary tuberculosis with aspergilloma in the remaining left lung, empyema with bronchopleural fistula had developed on the post-operative 4th day after completion pneumonectomy. Closed thoracostomy was done at the lowest point of the left pleural cavity immediately. The pleural cavity was irrigated with small amount of normal saline through pigtail catheter. The 2nd operation was done by closure of bronchopleural fistula using a stapler through transsternal, transpericardial approach, and then the pleural space was irrigated with normal saline with Tobramycin which shows sensitivity to isolated organism from pleural cavity. After negative conversion of pleural fluid culture, we performed modified Clagett's operation under local anesthesia. The patient had no evidence of recurrence of empyema and discharged from hospital after 10 days of the 3rd procedure.

  • For us, any regional art exist? Almost all art events today take place mostly in Seoul. Concentrating on the reinforcement of its power, the regional art world remains isolated without any connection with the Seoul art community. It is completely closed off from the central art scene. The regional art world seems to consider that more helpful in consolidating its status. It is in real sense suffering the absence of art criticism and art media, lack of an understanding of art and backwardness of art education. Many regional artists are dreaming of moving out from their domain, aspiring to be a member of the central art world. They make an effort to assimilate into a refined, modern style of the central art circle, rather than striving to create works imbued with regionality and locality. As the artists living in the provinces, the characteristics of their district should be above all else reflected in their art. Although they are less informed about the latest trend of culture and art, their art has to be something passionately and obstinately embodying the intrinsic quality of their regions. They have to find a practical solution more positively, instead of merely complaining about the poor condition of the regional art community. There is the need to bring about a turnabout in our awareness that regional art is confined to any limit and cannot be in the center of the entire art world. What' s most significant is to dissolve factionalism and not to depend on school ties or regional networks. As a reaction against authoritarianism, regional art has to put emphasis on attaining its originality. For this, regional art should respect regional tradition, history and background and break away from an old convention of wielding power.

  • William Wordsworth's "The Thorn" revolves around the following questions: Who is Martha? Why does she go to the mountain top and repeat her doleful cry? To these questions, it gives us two different kinds of answers; one derives from the villagers, and the other from the narrator. This essay attempts to examine how the answers exemplify two different critical approaches to the problem of community, using Jacques Lacan's account of sexual difference in his seminar on Encore as a guiding thread of analysis. The important thing to retain here is that sexual difference in Lacan's seminar on Encore does not so much indicate biological determinations as two distinct forms of relating to the other which are intimately bound up with the question of how a community is constructed and maintained. The first form, called "masculine," suggests that it is a radical exception to a community that makes possible the community as a field of totality or sameness; the second form, called "feminine," shows that each of the subjects cannot be regarded as a member of a closed community which is guaranteed by the exceptionality, but as an exception that is radically singular. This in turn leads us to consider the possibility that the masculine form has to do with the villagers' effort to distinguish themselves from Martha and the feminine form with the way in which the narrator confronts and represents her. In the course of his formulation of sexuation graph, Lacan stresses that the masculine side must be supplemented by the feminine side, which allows us to elaborate on why, concerning Martha, the narrator does not just keep the completely different position from the villagers'. This is to say that the villagers' representation of Martha as an exception to the community should be supplemented by the narrator's attempt to tell Martha's story as the villagers do and at the same time to capture something of her enigmatic unrepresentability. Bearing in mind Charles Shepherdson's elaboration of traumatic memory, this essay also tries to clarify how the narrator preserves and even transmits something of Martha's truth that is embodied in her uncontrollable and unassimilable cry.

  • Despite the importance and necessity, the 3PL has not been activated to date. Among many views, customers claim that logistics service provider(LSP) are not prepared or capable of offering satisfactory 3PL services, while LSP emphasize the lack of mutual trust, closed corporate culture of the customer and excessive demand for reducing the costs. With this keeping in mind, it surveyed difference of perception between users and providers of 3PL services in terms of the actual status of using 3PL services, the degree of satisfaction and key factors for selecting 3PL provider through the questionnaire. As shown in this study, 43.3% of the respondents outsourced logistics services. However, Most company outsourced only inland transportation (49.5%) which is a simple and limited scope of 3PL services, but it also indicated that the percentage of users have ranged was less then 10% in outsourcing their whole logistics sector to 3PL provider and employing other logistics functions. Among respondents, a majority of the service provider stated that they offered satisfactory cost-saving to the customers, while users felt that the degree of satisfaction for using 3PL services was evaluated as at an average level and they more highly regarded the strong partnership of their 3PL provider rather than the saving of cost and improvement of customer's services. Moreover, in contrast to the 3PL providers which regard the most important factor for selecting 3PL service provider is the logistics cost quoted, users of 3PL services felt that the quality of services was more significant than the reduction of cost, and this tendency for selecting 3PL providers was shown in more advanced countries. While users of 3PL services indicated that the main reason for not using 3PL services was to avoid disclosing information of their business and it costs much for employing 3PL providers than doing themselves, 3PL providers thought it was due to reluctancy of opening information and resistance from the logistics division engaged in logistics activities concerned. Accordingly, providers and users of 3PL services should trust each other and prepare plan to activate 3PL services under the collaborative relationships as soon as possible.

  • The International Electrotechnical Commission (IEC) 62494-1 has defined the exposure index (EI) that have a proportional relationship with the dose incident on the image receptor, and target exposure index (EIT), deviation index (DI). In this study, an appropriate EIT for skull radiography was established through the diagnostic reference level (DRL) and changes in DI were confirmed. Entrance surface dose (ESD) and EI were obtained using the computed radiography system displayed the EI as per IEC on console and skull phantom by experiment based on the national average exposure conditions announced in 2012 and 2019. And appropriate EIT was established by applying the DRL in 2012 and 2019. As a results, the EIT is changed according to the change in the DRL, and the exposure condition that becomes the ideal DI according to the change in the EIT also has a difference of about 1.41 times. DRL is recommended to optimize the patient dose, however it is difficult to measure in real time at medical institutions whereas EI and DI are displayed on the console at the same time as exposure. When the EIT is set based on the DRL and the DI is closed to an ideal value, it is useful as a patient dose management tool. Therefore, when the EIT is periodically managed along with the revision of the DRLs, the patient dose can be optimized through the EI, EIT and DI.
