  • 용수 다소비 산업으로 분류되는 제지공업의 특성 상, 용수사용의 억제 및 용수의 무방류화에 대한 압력이 증가되고 있는 반면, 초지환경은 날로 열악해지고 있는 실정이다. 한 예로써, 용지의 재활용율 및 재사용 비율이 증가함에 따라 원료의 저급화가 심 각한 수준에 이르고 있으며, 이러한 초지환경의 변화는 각질화되고 극도로 미세화된 다량의 미세섬유 발생 및 잡고지로부터 유입되는 점착성 이물질과 무기 충진제의 도입 등을 유발함으로서 제품의 물리적 성질 저하, 탈수부하 증가로 인한 생산성 저하, 약품사용량 증가 등을 초래하여, 결과적으로는 폐수처리장의 부하를 증대시킴과 동시에 청수사용량 및 폐수방류량을 증가시키는 악순환을 되풀이하게 된다. 국내 제지산업이 국제적 경쟁력을 갖추기 위해서는 제품의 증대가 필수적이나, 원료와 설비의존도를 감안할 때, 제품특성과 공정 분을 결정하는 습부공정을 정확히 파악하여 최적 운전조건을 확립하는 것이 가장 경제적이고 용이한 방법일 뿐만 아니라 전체 제지공정의 정정화에도 기여할 수 있을 것으로 판단된다. 일정규모이상의 종이를 생산하는 제지공장은 거의 대부분 컴퓨터로 처리되는 온라인 공정조절 시스템(On-line process control system)을 구비하고 료의 도입에서부터 설비운전 및 제품의 기본적인 품질관리까지 실시간의 자동화되고 안정적인 운전과 관리시스템을 유지하고 있다. 그러나 전체 제지공정 중, 제품 물성과 운전조건의 대부분을 결정하는 습부공정만큼은 아직도 주기적인 분석이 행해지고 있지 않을 뿐만 아니라, 슬러리의 농도나 보류도 정도를 제이하면 분석항목 조차도 변변히 확립되어 있지 않을 실정이다. 이는 다량의 물 속에 존재하게 되는 용전물질(Dissolved solids, DS), 부유물질(Suspended solids, SS), 섬 유(Fibers), 무기 미 세분(Inorganic f fines), 그리고 투입되는 약품간에 발생하는 계면동전현상 및 이러한 현상과 최종 지제 품의 물성간의 상관관계에 대한 이해 정도나 경험 부족에서 기인하는 것으로 생각된다. 1 1983년 미국제지기술연합회(T APpI)의 제지용 첨가제 분과위원회(Papermaking A Additive Committee)에서는 습부공정의 적절한 조절을 위해 어떤 항목들이 필요하며 그 중요도는 어떠한가를 조사하였으며, 그 결과로 전하밀도, 제타전위, 보류도 및 여수 도, 무기 미세분 함량 등이 중요하다고 보고하였다. 그러나 지료의 전기적 특성을 실시 간으로 측정하는 기자재류가 최근에 이르러서야 도입되고 있는 실정이기 때문에 충분 한 현장적용 사례가 보고되지 못하고 있으며, 결과적으로 얻어진 정보와 최종 지제품의 물성 및 초지기 운전조건과의 상관관계를 확립하는 작업결과는 더욱 찾아보기 어렵다. 따라서, 본 연구에서는, 라이너지 제조공장의 습부공정에 투입되는 약품이 지료 의 전기적 성질, 즉 전하밀도와 제타전위에 미치는 영향을 모니터링함으로서 지료의 전기적 성질들과 습부 공정상태와의 상관관계를 살펴보고자 하였다. 본 연구는 다음과 같은 순서로 진행하였다.

  • This study examines the determinants of the long-run stock price performance of the firms that granted stock options between 1997 and 2002. We divide the sample into the firms run by the owner and those run by the professional manager. If the primary reason for granting stock options is reduction of the agency costs between the manager and shareholders, the effect of stock options is likely to be more pronounced in the firms run by the professional manager. We find that the long-run abnormal returns of the firms run by the professional manager are negatively associated with the shareholdings by the manager and the book-to-market value and are positively associated with the earnings growth and the size of the outstanding stock options. In contrast, the long-run abnormal returns of the firms run by the owner are negatively associated with the cash flows rate and the sales growth rate and are positively associated with the firm size. This is consistent with the argument that the agency costs arising from the conflicts between the manager and shareholders are an important determinant of the post-stock option granting long-run stock price performance only in the firms run by the professional manager. The results also suggest that stock options in the firms run by the owner are likely to be used for the purposes such as additional compensation, a signaling device, a means that reduce the agency costs within firms.

  • Objectives: To find evidence that sleep is necessary for normal brain function, thus indicating that declines in both sleep quality and quantity are related to worse performance of many daily tasks and deteriorated physical functions. The present study investigates the relationships of balance control and reaction time with sleep quality. Methods: 58 healthy (male 20, female 38) volunteers with informed consent participated in this study. The Self-reported Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality and relevant factors, and the subjects were divided into groups A (PSQI < 5) and B ($PSQI{\geq}5$) based on this index. Static balance control and reaction time to visual stimuli were conducted to assess their relationship with sleep quality. Results: Group B exhibited excessive daytime sleepiness significantly more often compared to group A. Static balance control did not markedly change relative to sleep quality, but reaction time and error to visual stimuli were significantly increased in group B compared to group A. Conclusion: These findings indicate that a decline in sleep quality can result in delayed reactions, as well as decreased accuracy of these reactions. They also suggest that low sleep quality may be associated with changes in physical functions, including balance control through reduced selective attention.

  • This study examined the gait ability and foot pressure after backward walking training in hemiplegia patients after stroke to provide evidence for the application of backward walking to the rehabilitation of those patients. Twenty hemiplegia patients hospitalized at one rehabilitation hospital were enrolled in this study, which was conducted from 23 April to 18 May, 2012. The subjects were randomized into either the experimental group or control group. The control group received general physical therapy for 30 minutes and the experimental group received 20 minutes of physical therapy and 10 minutes of backwards walking training five times a week for four weeks. The gait ability and foot pressure of both feet were measured quantitatively and compared. The results showed the weight bearing (entire foot, anterior and posterior of foot) of the paralyzed foot during the stance phase showed a significant difference (p<.05). The difference in the foot pressure of right and left feet was more significant in the experimental group than that of the control group (p<.05). Therefore, this study confirmed that backward walking training in a rehabilitation program would be helpful for improving the gait ability of hemiplegia patients after stroke.

  • The donor pool for heart transplants is severely limited and there is still a legal problem of brain death. This study assessed the function of hearts "absolute anoxic" for ten minutes after asphyxia by perfusing the hearts on a Langendorfr apparatus for 45 minutes with Krebs-Henseleit buffier at 37 t at 80 cm H2O. Forty isolated rat hearts were divided into four groups. Ten control hearts (group 1) were perfused on the circuit without intervening ischemia. Ten hearts (group 2) were harvested, quickly flushed with 5cc of cold University of Wisconsin solution, and stored in the same cold solution for 4 hours. Ten hearts (group 3) were excised, quickly flushed with 5 u of cold Stanford cardioplegic solution and stored in cold saline solution for 4 hours. Ten asphyxiated hearts (group 4) had warm ischemia for ten minutes and were perfused with 5u of cold Stanford cardioplegia containing 7,500 units of urokinase to dissolve intravascular clots, and stored in cold saline solution for 1.5 hours. Time of spontaneous defibrillation (TSD) after perfusion was significantly longer in group 2, group 3 and group 4 than in group 1. TSD in group 3 and group 4 was significantly longer in comparison to that of group 2. Left ventricular developed pressure(LVDP) at 15 minutes was significantly lower in group 3 and group 4 than in group 1 and group 2. In group 4, LVDP at 30 minutes and 45 minutes was significantly lower compared with that in group 1 . In conclusion, asphyxiated rat hear;ts which had absolute anoxia for 10 minutes after as hyxia showed relatively satisfactory cardiac function. function.

  • We investigated seasonal changes in the marine environments and phytoplankton communities in the western part of south coastal waters of Korea during May 2009 and February 2010. In multidimensional scaling analysis of in situ data obtained by shipboard observations, the coastal waters comprised four different water masses: Yellow Sea water mass (YW) of low temperature and salinity, and high suspended solids and nutrient concentrations; south-western coastal water mass (SW) of high salinity and nutrient concentrations; Tsushima Current water mass (TW) of low nutrient concentrations, and high temperature and salinity; and closed bay water mass (CW). The spatial extent of these water masses varied according to seasonal environmental characteristics. In particular, at most study sites, TW expanded during autumn toward coastal waters. Phytoplankton abundances peaked during autumn in CW and spring in YW, which coincided with periods of high nutrient concentrations. In particular, diatoms predominated, and attained an abundance of more than 90% in most water masses. However, dinoflagellates in TW comprised a proportion of approximately 20% abundance.

  • With the development of artificial intelligence, artificial intelligence is being introduced to automate systems throughout the industry. In the maritime industry, artificial intelligence is being applied step by step, through the paradigm of autonomous ships. In line with this trend, ABS and DNV have published guidelines for autonomous vessels. However, there is a possibility that the risk of artificial intelligence has not been sufficiently considered, as the classification guidelines describe the requirements from the perspective of ship operation and marine service. Thus in this study, using the standards established by the ISO/ IEC JTC1/SC42 artificial intelligence division, classification requirements are classified as the causes of risk, and a measure that can evaluate risks through the combination of risk causes and artificial intelligence metrics want to use. Through the combination of the risk causes of artificial intelligence proposed in this study and the characteristics to evaluate them, it is thought that it will be beneficial in defining and identifying the risks arising from the introduction of artificial intelligence into the marine system. It is expected that it will enable the creation of more detailed and specific safety requirements for autonomous ships.
