吸着劑를 利用한 金屬 이온 및 有害物質의 吸着除去에 관한 硏究 : Comparison of removal effects of activated carbon, chitosan and delignified saw dust on metal ions and some hazardous materials 활성탄, Chitosan 및 탈 Lignin 톱밥의 금속이온 및 유해물질 흡착제거 성능의 비교

김용범,김현갑,김용우,손호영 서울産業大學校 1994 논문집 Vol.39 No.1

전통적인 흡착물질로 가장 많이 애용되어 온 활성탄(AC)과 새로히 개발된 천연고분자 물질 chitosan(CS) 및 脫 lignin톱밥(SD)으로 각각의 여과용 column을 만들고 음용수에 인위적으로 혼입해 둔 pb²+, Cd²+, Cu²+, Mn²+ 및 CN-에 대한 흡착 제거 성능을 비교 연구 하였다. 음용수에 혼입한 각 물질의 원 농도는 Pb²+; 3ppm, Cu²+; 3.1ppm, Mn²+; 0.7ppm, CN;5.3ppm였으며 이들 물질로 각각 단일용액을 조제하여 실험할때는 유속을 1.33㎤/min으로, 혼합용액으로 실험할때는 0.74㎤/min으로 하고, 충전된 흡착제의 건조 중량은 각가 10g으로 하여 흡착제거 실험을 하였다. 위의 각각의 단일 물질 용액에 대한 흡착제의 단위 중량(g)당 파괴점까지의 제거 용량은 Pb²+의 경우, 활성탄이 3.3ℓ, 탈 lignin톱밥이 3.5ℓ로 나타났고, Mn²+의 경우 활성탄이 10ℓ, 탈 lignin톱밥이 12ℓ, chitosan은 12.5ℓ로 나타났으며, CN-의 경우에는 활성탄이 4.8ℓ, 탈 lignin톱밥이 5.5ℓ, chitosan은 4.7ℓ로 각각 나타났다. 이들 혼합용액에 대해서는 단위 중량(g)당 파괴점까지의 흡착제거 용량은 pb²+의 경우, 활성탄이 2.5ℓ, 탈 lignin톱밥이 2.8ℓ, chitosan은 2.7ℓ로 나타났고, Cd²+의 경우, 활성탄이 2.4ℓ탈 lignin톱밥이 2.7ℓ,chitosan은 2.4ℓ로 나타났으며, Cu²+경우에는 활성탄이 2.8ℓ탈 lignin톱밥이 3.2ℓ, chitosan은 2.7ℓ로 나타났다. 대체로 Pb²+, Cd²+, Mn²+ 등 금속이온에 대한 흡착제거에 있어서는 탈 lignin톱밥과 chitosan의 경우가 활성탄보다는 10~30%정도 높은 제거율을 보였으며, CN-에 대해서는 탈 lignin톱밥>활성탄>chitosan의 순으로 제거 효율을 나타내었다. Some adsorbents prepared from natural resorces were subjected to the experiments of removing some metal ions(pb²+, Cd²+, Cu²+ and Mn²+)and cyanide. The adsorbents applied in the experiments were activated carbon, delignified saw dust and chitosan powder, each of which was packed into a column in order to remove metal ions and cyanide artificially contaminated in the potable water, functioning as filters. The most effective adsorbent was found to be the delignified saw dust column in removing contaminants and activated carbon column was found the poorest among the three. Delignified saw dust demonstrated to be a most effective, cheaper and popular filtering saw dust demonstrated to be a most effective, cheaper and popular filtering material for the purification of potable water which most citizens are not yet confident with.

과립상 세포종은 Schwann 세포 기원으로 생각되며 인체에 비교적 드물게 발생한다. 과립상 세포종은 전신 어느 곳에서나 발견될 수 있으나 주로 혀, 구강, 피부 혹은 유방 등에서 호발하며 드물게 위장관에서 발견된다. 위장관에서는 식도에서 가장 호발하며 다음으로 위, 대장 순이다. 과립상 세포종은 대부분, 특히 위장관에서는 양성이며 소수의 악성 병변이 보고되었다. 이러한 이유와 함께 수술 전의 진단이 어렵기 때문에 과립상 세포종에 대한 근본적인 치료는 현재까지 외과적 절제술이다. 최근에 시도되는 치료방법들로는 내시경적 레이저 치료, 용종절제술, 내시경적 점막 절제술 등이 있다. 저자들은 상부 소화관 내시경검사를 시행하여 식도 과립상 세포종을 진단하고 내시경적 점막 절제술을 시행하여 합병증 없이 퇴원하여 현재 재발없이 경과 관찰중인 1례를 경험하였기에 보고하는 바이다. Granular cell tumors, which occur infrequently, are probably of Schwann cell origin. They can occur almost anywhere in the body but usually affect the tongue, oral cavity, skin, or breasts and are rarely found in the gastrointestinal tracts. The esophagus is the most frequent gastrointestinal site, followed by the stomach and the colon. Granular cell tumors are generally benign, especially in the gastrointestinal tract, some malignant lesions have been reported. For this reason, and also because preoperative diagnosis is difficult, the standard treatment for granular cell tumor has until now been surgical excision. In recent years, other therapeutic methods is endoscopic laser therapy (ELT), polypectiomy, endoscopic mucosal resection (EMR). We report a case of esophageal granular cell tumor which was diagnosed by an endoscopy and managed using an endoscopic mucosal resection without complication.

Diazepam과 Lidocaine이 노인환자의 기관내삽관시 심전도 및 심맥관계에 미치는 영향

김경희,권성범,신용섭,최세진 충남대학교 의과대학 지역사회의학연구소 1995 충남의대잡지 Vol.22 No.1

We selected at random 30 geriatric patients who had received operation under the general anesthesia with endotracheal intubation. The patients were divided into 3 groups. Group 1 (control) had received endotracheal intubation without diazepam and lidocaine. Group 2 had received endotracheal intubation with diazepam. Group 3 had received endotracheal intubation with lidocaine. The changes of arterial blood pressure and pulse rate, and the appearance of arrhythmia were compared in each group. The results were as follows : 1. The increase of blood pressure and heart rate were less in group 2, 3 than the control group which showed significant increase of blood pressure and heart rate with endotracheal intubation. 2. The incidence of arrhythmias with endotracheal intubation was less in group 2(20%), group 3(50%) than the control group(80%). 3. The electrocardiographic change in the group 2 and 3 were not significant compared to group 1(control).

현재 전자무역시스템과 관련되어 주목받고 있는 것으로는 볼레로(Bolero), SWIFT, 그리고 무역카트(Trade Card) 시스템이 대표적이다. 볼레로는 전자선하증권, SWIFT는 전자신용장, 무역카드는 새로운 전자무역시스템을 통한 전자결제를 언급하고 있다. 특히 전자신용장 방식의 결제측면에서 볼레로와 SWIFT는 매우 깊은 연관을 가지고 있으며, eUCP의 발표로 인하여 신용장 방식의 전자화 및 전자결제의 가능성을 더욱 높이고 있다. 한편 무역카드는 신용장을 배제한 전자교역 절차와 기업의 신용평가 및 지급보증을 통해서 전자결제의 안정성을 도모하고 있다. 이러한 전자무역시스템은 각각 특유의 법률 그리고 기술구조를 가지고 있으며 관련업체를 유인할 수 있는 장점을 가지고 있으나 단점 또한 적지 않다. 따라서 본고는 볼레로, SWIFT, 무역카드로 대변되는 전자선하증권, 전자신용장, 전자결제시스템의 법률 및 기술상의 유용성과 문제점 그리고 향후 대응전략을 살펴보고 있다. BOLERO System, SWIFT, and Trade Card System have recently been used as major electronic payment systems in relation to the electronic trade. Electronic bill of lading from BOLERO, electronic letter from credit of SWIFT, and a new electronic trade procedure from Trade Card as the payment systems are covered in this paper. These electronic payment systems have some merits to attract trade-related companies, but it is also true that they hold the legal and technical problems. In other words, there still remain some problems that these transaction procedures have to solve in order to match the established one. However, these systems will eventually be settled down as the global electronic trade methods, as actual experiences from those transactions accumulate more and more. Specifically, we have to remember that a future plan of BOLERO is not expansion of the electronic Bill of lading, but the electronic trade. Thus this paper prepares for the conditions that SWIFT service could be provided by the Internet of combined with various electronic transaction model. It also prepares for legal instability of the Trade Card system in building electronic process of trade firms.

근로관계와 경영권의 법적성질에 관한 연구

金龍華,金範基 호남대학교 2005 호남대학교 학술논문집 Vol.26 No.1

Employment relations are established on the basis of an employment contract in principle, closely related each other and at the same time are legal relations that bind mutually. Furthermore, a management right and unityㆍcollective action right are mutually restricted relations. With the realization of democratization of labor-management relations, the use of the right has been developed into accepting mutual limitation. Although unity action was only activity of citizens' collective expression in the level of civil laws, it could have legal approval of special protective exemption in an aspect of labor laws through an amendment to a principle of civil laws. Its objective is to secure criminal and civil exemption of union activity and to prohibit unifair labor action, which is originally implied in the constitution. Accordingly, interpretation theory that distinguishes unity action from the beginning cannot be accepted. It is because both a strike and unity action by agreement pursue a common goal to realize the value of right to live. Employment relations are formed on the basis of the mutual rightㆍobligation of employer and employee. While employees have the obligation to provide agreed labor in employment relations, an emloyer has a claim to provide labor against employees in principle. Employer's right to use or dispose employees' labor as a company manager for the purpose of business can be acquired by contract with employees. There is no way to dispose such labor in employer's own right free from such contract relations. Employees should obey employer's command and order in the process of providing labor and follow manager's measures to maintain management facilities and order. In the words, employees should provide labor according to employer's right to command labor that is specific indication of a claim to provide labor, and at tne same time observe management order based on employer's right to own management facilities and to control facilities. On the other hand, the concept of a management right is employer's own right. Although a precedent admits it as a legal right, it cannot be admitted as a right based on the positive law. But its scope of execution as a decision making right reserved to an employer also is limited to legal matters. While some deny the existence of a management right on the basis of its fail to prescibe specifically in constitution or laws like the trade union right, others argue that a management right should be admitted as a nature right because an organizational consistency must be maintained with the management of a property right, considering that constitution ensures it as a property right. Manger's right of management is economic power that controls land, labor, wealth, or company production and may be understood as a series of right of property operation that a manger(capitalist) owns means of production, combines them organizationally, and conduct production activity. Moreover, today a capital has been separated from management. Managers should be responsible for company's environment and have the function to fulfill the responsibility as their own right. Some argue that it is managers' exclusive decision matters that do not need to discuss in collective bargaining, which is called a management right. Such a management right is company's own function and governs labor-managemant relations. However, the problem is whether there is manger's management right correspondent to employees' labor right. While the trade union right is expressly stipulated in the text of constitution or labor relations laws, a management employment relations and its relations with a management right, and the legal meaning and nature of a management right, which is very important in the right of the establish modern characteristics of labor-management right and the concept of a management right that meets in reailty.
