In vitro evaluation and physiological control
인공심장박동기는 1950년대 말기에 처음 개발된 이래로 주로 서맥성 부정맥의 치료에 이용되고 있다. 1990년대 중반의 미국에서 인공심장박동기의 시술을 보면 53%는 동기능부전증후군에서, 31%는 방실결절질환에서 사용된다. 따라서 약 10-15%는 서맥성 부정
control the variety of the environment.

Peptides are released by neurosecretory nuclei of the hypothalamus into the hypophyseal portal venous blood surrounding the pituitary which are the major controllers of GH secretion by the somatotropes.
balance of these stimulating and inhibiting peptides determines GH release, this balance is affected by many physiological stimulators (e.g., exercise, nutrition, sleep) and inhibitors of GH s
regular and temporary employees perform same work in same level, temporary employees have to receive less pay. Inequity causes anger of temporary employees, and forces them to work worse to meet the degree of the salary.
Sure, managers try to make norms to control performance of temporary employees, for example, monitoring system, but the communication way of down-up rarely happens as they

I. 욕구이론
사회복지에서 욕구에 대해 가장 널린 알려진 것은 Maslow의 욕구단계이론(Hierarchy of Needs Theory)이다. 욕구에 대한 고전적인 분류인 Maslow(1954) 의 5단계 구분을 살펴보면, 인간의 욕구는 생리적 욕구(physiological needs), 안전에 대한 욕구(safe needs), 소속과 사랑의 욕구(belongingness and love needs), 자아
