1. Objectives: We report the relation between the questionnaire and the health state on the Sasang Constitution. 2. Methods: We carried out a clinical test, in which 2 Oriental medical doctors participated to diagnose health state in each Sasang Constitution with 239 subjects. The subjects were divided into 3 subgroups, which are allocated to healthy group, poor health group and disease group. 3. Results: We extracted 4 questions for Taeeumin, 5 questions for Soyangin and 3 questions for Soeumin from the whole 98 questions respectively. Soyangin and Taeeumin share a same question that shows significant difference by health status. For the statistical analysis, we used a Chi-square test. As a result, we found out that Taeeumin showed different distributions of answers in direct/indirect characteristic, perspiration, frequent urination, regular defecation. According to the health status Soyangin showed the different distribution of the answers in color of urination, frequent urination, mouth dryness, abnormal perspiration, discomfort of head. Soeumin showed the different distribution of the answers in cold and chilly feel of abdomen, digestion status and cause of digestion problems when body condition gets worse. 4. Conclusions: This is the first work which reports the relatedness between Questionnaire and Health State in each Sasang Constitutions by an objective clinical test. We found out that several questions have different distributions by health status in each Sasang Constitution. These extracted questions are categorized not only by Wansilmoobyung(완실무병), but also by other symptoms and body status.

The broadband and discrete sources of sound in small cooling fans of propeller type and centrifugal type were investigated to understand the turbulent vortex structures from many bladed fans using ANSI test plenum for small air-moving devices (AMDs). The noise measurement method uses the plenum as a test apparatus to determine the acoustic source spectral density function at each operating conditions similar to real engineering applications based on acoustic similarity laws. The characteristics of fans including the head rise vs. volumetric flow rate performance were measured using a performance test facility. The sound power spectrum is decomposed into two non-dimensional functions: an acoustic source spectral distribution function F(St,.phi.) and an acoustic system response function G(He,.phi.) where St, He, and .phi. are the Strouhal number, the Helmholtz number, and the volumetric flow rate coefficient, respectively. The autospectra of radiated noise measurements for the fan operating at several volumetric flow rates,.phi., are analyzed using acoustical similarity. The rotating stall in the small propeller fan with a bell-mouth guided is mainly due to a leading edge separation. It creates a blockage in the passage and the reduction in the flow rate. The sound power levels with respect to the rotational speeds were measured to reveal the mechanisms of stall and/or surge for different loading conditions and geometries, for example, fans installed with a impinging plate. Lee and Meecham (1993) studied the effect of the large-scale motions like impinging normally on a flat plate using Large-Eddy Simulation(LES) and Lighthill's analogy.[ASME Winter Annual Meeting 1993, 93-WA/NCA-22]. The dipole and quadrupole sources in the fans tested are shown closely related to the vortex structures involved using cross-correlations of the hot-wire and microphone signals.

Dragonet fish (Callionymidae), living in benthic upper 900 m of all subtropical, tropical and temperate oceans, comprises 200 species in 20 genera worldwide, of which 18 species in 6 genera occur in Korea. Although dragonet fish plays an important role in linking between top predators and lower trophic levels, there are only few studies about their early life history. Herein, we present molecular and morphological data on larvae and juveniles of Bathycallionymus kaianus (Günther, 1880) collected from the Korean waters. During 2016 to 2018, one preflexion larvae [2.69 in total length (TL)], three flexion larvae (3.65 and 4.77 mm TL), six postflexion larvae (6.07 and 7.94 mm TL), and three juveniles (10.81 and 12.26 mm TL) were collected in the East Sea, Korea Strait, and Jeju Island using Bongo net. Of them, 13 individuals were identified through molecular markers (COI or 16S rRNA) and morphologically described. The larvae of B. kaianus are well distinguished from other species of Callionymidae in melanophore distribution, body shape and development of preopercular spine. It was very similar to larvae of two Repomucenus species, R. valenciennei and R. virgis, but was clearly distinguished in melanophore distribution, preopercular spine development, and head shape.

In order to understand the distribution of changes of geochemical characteristics in surface sediments according to various environmental changes around the artificial Lake Shihwa, surface sediments were sampled at $13{\sim}15$ sites form 1997 to 1999 and analyzed by C/S analyzer, ICP/MS and AAS. The average $S/C_{org}$ ratio was 0.35 in the surface sediments, which is similar to 0.36, the characteristic ratio of marine sediments. Heavy metal contents and enrichment factors in the surface sediments tended to be decreasing from the head to the mouth of the Lake Shihwa. With the deposition of fine-grained sediments in the central part of lake, anoxic water column induced the sulfides compounds with Cu, Cd and Zn. Metals such as Al, Fe, Cr, Co, Ni, Cu, Zn and Cd except for Mn and Pb showed relatively high correlation coefficients among them. The contents of Cr, Co, Ni, Cu, Zn and Cd in the surface sediments of the lake were two to five times higher than those in the lake before dike construction and also in outer part of the dike. These are mainly due to the Input of untreated industrial and municipal waste-waters into the lake, and the accumulation of heavy metals by limitation of physical mixing. Although metal contents of the surface sediments at the sites near the water-gate due to outer seawater inflow tended to be lower than those during the desalination, heavy metals were deposited in areas around the new industrial complex in the evidence of spatial distribution of heavy metals in the sediments. This is mainly due to the input of untreated waste-waters from tributaries.

수영만으로 유입되는 수영강수에 의한 하구의 물리적인 특성을 밝히기 위하여 1989년 5월부터 1990년 4월까지 월별로 관측된 염분 자료와 Officer(1977)가 제안한 식을 이용하여 담수량 및 그 체류 시간을 계산하였다. 그 결과, 수평적으로는 수영만의 동백섬을 기준으로 수영강과 접하고 있는 만 안쪽으로 저염화가 강하게 나타나고 연직적으로는 강 혼합과 부분 혼합의 특징이 나타났다. 그리고 수영강을 중심으로 광안리 쪽이 해운대쪽보다 높은 담수율을 나타내었다. 그리고 거리에 따른 담수율의 분포 특성을 알아보기 위하여 수영강에서 외해쪽으로 6개 정점에서 각각 계산한 담수율을 각각의 최대치로 나누어 계절별로 정규화한 결과 담수율이 지수함수적으로 감소하였다. 추계에는 정점C3를 기준으로 감소율이 다른 계절에 비해 현저히 떨어졌는데, 이것은 성층에 기인한 것으로 보인다. 그리고 앞에서 구한 담수율을 이용하여 수영강에서 유입되는 담수의 체류시간을 계산한 결과, 약 1.3일인 하계를 제외하고 나머지 계절은 약 10~15일 정도임이 밝혀져 하계가 다른 계절이 비하여 담수의 순환이 빠름을 알 수 있었다.

This paper is the fifth investigation on the methods of evaluating flow characteristics in a steady flow bench. In previous studies, several assumptions used in the steady flow bench were examined and it was concluded that the assumption of the solid rotation may lead to serious problems. In addition, though the velocity profiles were improved as the measuring position went downstream, the distributions were far from ideal regardless of the valve angle and evaluation position. The eccentricities were also not sufficiently small to disregard the effect on impulse swirl meter (ISM) measurement. Therefore, the effect of these distribution and eccentricity changes according to the positions needs to be analyzed to discuss the method of flow characteristics estimation. In this context, the effects of evaluation position on the steady flow characteristics were studied. For this purpose, the swirl coefficient and swirl ratio were assessed and compared via measurement of the conventional ISM and calculation based on the velocity by particle image velocimetry(PIV) from 1.75B, 1.75 times bore position apart from the cylinder head, to the 6.00B position. The results show that the swirl coefficients by ISM strictly decrease and the curves as a function of the valve lift become smooth and linear as the measuring position goes downstream. However, the values through the calculation based on the PIV are higher at the farther position due to the approach of the tangential velocity profile to ideal. In addition, there exists an offset effect between the velocity distribution and eccentricity in the low valve lift range when the coefficients are estimated based on the swirl center. Finally, the curve of the swirl ratio by ISM and by PIV evaluation as a function the measuring position intersect around 5.00B plane except at $26^{\circ}$ valve angle.

The purpose of this study is to measure Korean, Chinese and Chosunjok college women's body part sizes, and then, classify their body shapes according to the drop value(hip circumference-chest circumference) as well as their statures, and thereupon, comparatively analyze the statistical distribution of their major body part measurements and thereby, provide for some basic data useful to the development of quality fitting apparels exportable to China. The results of this study can be summarized as follows; Most of Korean and Chinese college women were found to belong to the body type of "N" body shape, while many of Chosunjok college women belonged to "H" body shape body type characterized by normal stature but small difference between hip and chest circumferences. The most prevailing body type of Korean and Chinese college women next to "N" type(65%, 51%) was "H" (23%, 35%), followed by "A" type(12%, 14%), while that of Chosunjok college women was "H" type (54%), followed by "N" (40%) and "A" type (6%). On the other hand, in terms of distribution of major body part sizes, there was found a wide difference between Chinese and Korean college women. Chosunjok college women had similar body part sizes to Korean college women's in such measurements as waist back length, shoulder-to-shoulder length, front interscye length, back interscye length, under-chest circumference and weight, while having simliar body part sizes to Chinese college women's in such measures as stature, arm length, waist front length, waist side-hip line length, crotch length, head circumference, neck-root circumference and waist circumference.

Purpose : The purpose of this study was to investigate the change of the peak plantar pressure distribution under the foot areas and the range of motion (ROM) of ankle joint according to gradients in treadmill gait. Method : Thirty normal subjects (15 male and 15 female) walked on treadmill at three gradient conditions ($0^{\circ}$, $10^{\circ}$, and $15^{\circ}$) in normal speed. The ankle ROM was measured using the CMS70P that is three dimensional analyzer for excursion of ankle ROM, plantar flexion, and dorsi flexion. The peak plantar pressure distribution under the hallux, 1st metatarsal head (MTH) and heel was measured using the F -Scan system with an in-shoe sensor. Data was collected from 9 steps of left sife foot in at each gradient condition while all subjects walked. Result : As the treadmill gradient increased, the excursion of ankle joint was significantly increased (p<.05). Also, plantar flexion and dorsi flexion was significantly increased according to treadmill gradients (p<.05). The peak plantar pressure under the 1st MTH was significantly increased (p<.05) and the peak plantar pressure under the heel was significantly decreased (p<.05) as the treadmill gradient increased. No significant different in the peak plantar pressure under the hallux was observed. Conclusion : This study suggests that physical therapy for patients who have limited ankle ROM should be considered sufficient range of motion for functional ambulation. And individuals that have painful forefoot syndromes, including metatarsalgia, hallux valgus, and plantar ulceration should be careful in walking to uphill, as there is high plantar pressure under the forefoot.
