Now, Korean health technology and health service is proud to be world class one at a level of not falling behind anywhere in the world. However, this health service has been provided, centering on hospital or medical staff, not patient so far. And there is a tendency to gradually change into patient-centered health service. According to the results of survey performed by Korea Institute for Health and Social Affairs, it was reported that, as of 2016, 30% or more of inpatients were not sufficiently given information relating to hospital rounds, and in particular, 50% or more of inpatients in their twenties to thirties expressed discontent, and approximately 17% of inpatients in their seventies and beyond expressed discontent. In the light of these data, especially inpatients in their twenties to thirties want information relating to hospital rounds and the like. And taking into consideration that they are characterized by being accustomed to using a smartphone, it is intended to design and implement a hospital rounds information smartphone application. Now, in some of medium and large hospitals, information about hospital is provided through smartphone application. However, the main purpose is hospital information or outpatient's appointment to see a doctor and so on. Even in case of providing information about hospital rounds, only information about approximate time to make rounds is provided. This paper is intended to design and implement hospital rounds information system making it possible to check their turn when rounds are made by utilizing NFC function in smart phone.

Water temperature during the culturing period was 10.4-25.5$^{\circ}C$ and there was a little difference between rearing sites. Salinity (25.00-31.17 psu) and DO (over 6.13 mg/l) showed reasonable condition for the growth of bay scallop. Concentrations of chlorophyll-a were ranged 1.69-7.40 $^{\mu}$g/l, and they fluctuated monthly in the every sampling site. During the growing period from June to October, dominant phytoplankton species were Ceratium sp. in Nammeon and Hoejin, Chaetoceros sp. in Dolsan. Density of phytoplankton was high in July, August and October, but it was low in September and November. When young bay scallops were cultured for 185 days in Nammyeon, Hoejin and Dolsan, shell heights were grown for 0.19 mm/day, 0.18 mm/day and 0.16 mm/day, respectively, and total weights were increased 0.16 g/day, 0.16 g/day and 0.13 g/day, respectively. Daily growth rates of shell height were 0.606%, 0.581% and 0.549%, and daily growth rates of total weight were 1.972%, 1.857% and 1.746%, respectively. Maximum predicted values of shell height calculated by von Bertalanffy growth model were 52.62 mm, 51.74 mm and 48.91 mm, respectively. Survival rate was the highest in Nammyeon (87.0%), but the rates in Hoejin and Dolsan sharply decreased after November.

지금까지 알려진 내부마찰측정방법으로는 자유감쇄법(free decay method), 강제진동법(forced vibration method), 비공진강제진동법(non-resonance forced vibration method) 및 초음파법(ultrasoni method) 등이 있다. 이상의 모든 내부마찰실험방법에 관한 실험장치는 그 기계의 동작특성에 따라 실험주파수가 극히 한정되어 있어 연속적인 변화를 시킬 수 없으므로 완화효과를 연속적으로 추적하기 위하여 온도를 변화시키는 방법이 널리 사용되고 있다. 이상에서 소개한 방법들중 본인들이 국산제작실험에 성공한 바 있는 장치는 자유감쇄법에 속하는 염회진자장치(torsion pendulum device) 이므로 이 장치를 중심으로 내부마찰측정원리와 그의 장치에 관하여 소개하고저 한다.
