해수의 염도와 온도를 현장에서 측정할 수 있는 침적식 온라인 굴절계를 제작하고 실제 해수와 유사한 2 % 내지 4 %의 염수를 사용하여 그 성능을 조사하였다. 굴절률과 온도를 동시에 측정함으로 온도보상을 신속하게 할 수 있어 염도의 직접측정을 가능하게 하였다. 각기 다른 농도의 염용액에서 측정된 염도의 결과로부터 본 실험의 장치는 안정성과 재현성을 모두 갖는 염도 측정이 가능함을 알았다.

Cleft lip is one of the most common congenital deformities in craniofacial region. Despite the many reports on the outcome of various surgical techniques from individual medical centers, the evaluation of the outcome is based on the subjective observation because of lack of the objective evaluation system. Therefore, a new technique of objective and scientific evaluation for the nasal deformity of secondary cleft lip and nose deformity is critical to improve the management of the cleft patients including the decision of optimal age of operation and surgical technique as veil as evaluation of the outcome. In this study, a new method was proposed to evaluate the nasal deformity using nostril angle, distance, and area of patient images. The images were also evaluated by three expert plastic surgeons, and put into scale of 5 percentile. Measurement results were compared between the each category and the surgeon's evaluation, and coefficients of each category were statistically tested. As a result, The normalized overlap area of right and left nostrils and distance ratio between two centers of nostrils showed high coefficient with evaluations of plastic surgeons.

Objectives The present study retrospectively investigated clinical outcome of patients with structual scoliosis during Chuna treatment. Methods : The study population consisted of 34 patients(14 patients of adolescent and 20 patients of adult) who were diagnosised as scoliosis with radiological finding. All patients were treated with Chuna treatment, and after treatment, evaluated with radiological measurement by calculating the scoliosis correction angle from the Initial and follow-up spine AP and lateral views. Also the evaluation of clinical outcome was done twice pre and post treatment during this study. Results : The results were summarized as follows ; 1) The 85.3 percent of patients complained physical pain. and adult group had various painful lesion compared with adolescent group. 2) Adult group had treated $18.0{\pm}7.2$ times and adolescent group treated $13.5{\pm}5.7$ times with Chuna treatment. 3) Scoliotic angle is reduced in 92.9 percent of adolescent group and had all of adult group after Chuna treatment, especially, statistically significance appeared in adult group. 4) Adult group was superior to adolescent group in correctability and scoliotic angle change. 5) Correction effect was better in the group which initial scoliotic angle was lessor, or had more time of treatment. 6) According to grade of vertebral body rotation, scoliotic angle is larger and correctability was lower. Conclusions : Chuna treatment was efficacious against scoliosis. And it is necessary for adolescent scoliosis patient to be more carefully treated and observed.

Purpose: Service quality plays an important role in the credibility of consumer behavior as it enhances brand loyality in hospitality business. The objective of this study is to determine the effects of service quality, positive emotion, brand affection, and brand loyalty in restaurant sector by applying the S-O-R model. The study also introduces a new integrated structural model that combines service quality's dimensions of physical quality, interaction quality, and outcome quality. Research design, data, and methodology: This study was analyzed in a quantitative way using the survey results of 395 customers who had experience of visiting restaurants. All constructs were measured with multiple items developed and validated in prior studies. In this study, SmartPLS 4.0 was used to evaluate the research model. The reliability, convergent validity, and discriminant validity of the measurement tool were verified. Result: Result was found that service quality(physical quality, interaction quality, outcome quality) had a positive effect on positive emotion and brand affection. Also both of positive emotion and brand affection had a positive effect on brand loyalty. This study contributes to the service quality literature and has practical managerial implications.

The degree of supersaturation is an important measure for the operation of crystallization processes, because it is directly related to the control of crystal size distribution and shape. A conventional technique utilizing solution composition and temperature has a variety of problems caused from the measurement error and the handling of analyzing samples. A monitoring system of the supersaturation using a quartz crystal sensor is proposed here, and its performance is examined applying different manipulations of coolant temperature. The experimental outcome and photographic examination indicate that the measurements of resonant frequency and resistance of the sensor can be used for the prediction of the formation and growth of solid crystal from the crystallization process. The monitoring system eliminates the intrinsic error source of the conventional system to give the improved measurement and on-line application availability.

In the field of ophthalmology, many diagnostic instruments based on optical technology have been developed, such as refractometer, keratometer, corneal mapper, tonometer, fundus camera, slit lamp, laser scan ophthalmoscope and optical coherence tomography. Among them, the refractometer that is used for measuring the refractive power of the human eye has the long research history and various types have been developed. However the efforts to realize more accurate and precise measurement are still in progress. The wavefront analyzer commercialized in recent years is an excellent outcome of such efforts. In this paper, a brief account of the developmental history of various refractometers including the wavefront analyzer is summarized, and the underlying measurement principle is introduced in the view of optics. Finally, the technical issues that should be solved for getting better performance are discussed.

In this study, five experiments were carried out, with an orifice located downstream of a fan in case I and upstream distance to the fan in the rest cases(case $II{\sim}$), so as to determine the optimal location of the orifice and reduce the size of airflow measurement device. The resulting flow rate-pressure drop correlations were found to satisfy the limitation of SMACNA standard, which specified an error of ${\pm}7.5%$ based on the real flow rate. The best outcome was achieved with the orifice located midway of the orifice duct 4 times its diameter long.

Jaundice is common in breast-fed infants. Any infant noted to be jaundiced at 2 weeks of age need to be evaluated for cholestasis with measurement of total and direct serum bilirubin. The most common causes of cholestatic jaundice in infants are biliary atresia and neonatal hepatitis. Genetic causes of the neonatal hepatitis syndrome are increasingly recognized and idiopathic neonatal hepatitis is decreasing. Cholestasis should be investigated using a structured protocol. Early detection and timely, accurate diagnosis is important for successful treatment and a favorable prognosis. In particular, a Kasai portoenterostomy for biliary atresia has the best outcome if performed before the infant is 8 weeks of age. The management of cholestasis is mainly supportive, including nutritional support and alleviation of symptoms to improve the quality of life. Specific treatments are available for some causes of neonatal hepatitis syndrome and should be started as soon as possible. For decompensated liver disease, liver transplantation yields a better outcome.
