WDM(Wavelength Division Multiplexing) is called a wavelength division multiplexing optical transmission method and is a next-generation optical transmission technology. Case company F has recently developed and sold PLC(Planar Lightwave Circuit), a key element necessary for WDM system production. Although Chinese processing companies are being used as a global outsourcing strategy to increase price competitiveness by lowering manufacturing unit prices, the average defect rate of products manufactured by Chinese processing companies is more than 50%, causing many problems. However, Chinese processing companies are trying to avoid responsibility, saying that the cause of the defect is the defective PLC Wafer provided by Company F. Therefore, in this study, the responsibility of the PLC defect is clearly identified through estimating the defect rate of PLC using the sampling inspection method, and the improvement plan for each cause of the PLC defect for PLC yeild improvement is proposed. The result of this research will greatly contribute to eliminating the controversy over providing the cause of defects between global outsourcing companies and the head office. In addition, it is expected to form a partnership with Company F and a Chinese processing company, which will serve as a cornerstone for successful global outsourcing. In the future, it is necessary to increase the reliability of the PLC yield calculation by extracting more precisely the number of defects.

A nutrition survey of 152 children , in the kindergarten attached to a proivate elimentary school of Pusan, was undertaken between Dec. 1 and Dec.14, 1993, to investigate dietary intake and nutrition status. The results are summarized as follows. 1) Compared with the Korean child development standard, their development conditions showed 113.1% , 102.2% , 103.3%, 101.75 in weight, height, head and chest, respectively. 2) By the standard of WLI(Weight Length Index) , proper to the children between age 4 and 6 , there proved to be 25% overweight and 4% obesity, 25% overweight and 19% obesity , 28 overweight and 26% obesity in 4-year-old, 5 year-old, and 6 -year-old children, respectively. 3) The children between age 4 and 6 averaged 37.6% in hematocrit and 12.4-12.8 5 in hemoglobin. these values were higher than those of the Korea child development standard. but the numbers of erythocyte, leucocyte and platelets were normal . Only a single child was considered suffering from aenmia . The 8% of them were over 200mg/이 in cholesterol, dangerously approaching the atherosclerosis. The 31% averaged 120mg/이 in triglyceride . And the 6% proved 100mg/이 in blood glucose when hung교. So it came out that not a few children had some factors dangers to diabetes, atherosclerosis and heart diseases : complications arising from obesity. 4) The intake of nutrients , except the 4-year-old children , ranged 108.4% to 2665 from the recommended value. The rates of carbohydrate, fat and protein to be much correlation among total intake of nutrients, development , results of blood test and WLI. The degree of obesity was proportionate to the intake of nutrients.

To improve $B_1$ homogeneity in high field MRI, the RF power is applied to the transmit array coil elements sequentially in the time-multiplexed way. Since only a single coil element is activated in a time-multiplexing slot, the global standing wave formation in the human body is greatly suppressed. The time-multiplexing slot width is on the order of micro seconds, hence, high-order-harmonic slices can be placed far from the transmit coil and simultaneous multiple slice selection can be avoided. The $B_1$ homogeneities of a birdcage coil and an eight-channel transmit array coil have been compared through finite difference time domain simulations. The simulation results indicate that the proposed technique can reduce the peak-to-peak $B_1$ inhomogeneity down to one fourth of the transmission with a birdcage coil on the central plane of the human head model at 3 T. The mimicking experiments at 3 T, eight separate experiments with a single coil element activated and image reconstruction by combining the eight images, also show promising results. It is expected that the proposed technique has some advantages over other $B_1$ improving methods in real practice since simple RF switching circuitries are only necessary and electromagnetic coupling between the coil elements is out of concern in its realization.

Since the first description by Cotton, there have been sporadic reports about the inferior subluxation of the shoulder. Nevertheless there is still a lack of consensus regarding the mechanism of occurrence, evolution and treatment. We have experienced six cases of inferior sublusation(five cases after trauma and one case after surgery) which resolved over time. Analysis of the clinical informations including serial radiographs, data from clinical examination and electromyography(EMG) revealed the following results. All the five post-traumatic inferior subluxations were noted in women with an average age of 59 years after direct trauma resulting in fracture of the proxiaml hrnerus(4) or clavicle(1), of which nerve injury was proven by EMG in three. One case occurred after Bankart repair by stretch injury to the axillary nerve. The presenting symptom was unusually severe pain on passive motion. Absence of anterior or posterior displacement wasl confirmed by radiographs. All the cases seemed to have delayed onset of subluxation except one. The subluxed hu.meral head was concentrically reduced at an average 11 weeks(range 3-23 weeks) from the supposed time of occurrence and the acromiohumeral interval measUred on the standing anteroposterior radiographs decreased to 9.4 mm ftom 23 mm. Improvement of pain paralled the reduction. In conclusion, the most common cause of transient inferior subluxation was nerve injury in ou~ series and the prognosis was excellent, however protraction of recovery or leaving permanent subluxation would be possible if .the injured nerve is unrecoverable.

CT에서 대수적재구성기법은 잡음에 강점을 가지는 재구성기법으로 알려져 있다. 대수적재구성기법에서 반복 횟수는 계산 시간을 결정하는 중요한 인자 중의 하나이다. 그러나 반복 횟수에 대한 기준이 연구되어 있지만 수백 번 이상의 반복을 수행하게 되어 현실적으로 사용하기에는 무리가 있었다. 본 연구에서는 반복 횟수를 결정할 수 있는 현실적인 방법을 제시하였다. 반복 횟수에 따라 단면 영상의 품질이 천천히 개선된다는 것을 이용하였다. 반복 횟수를 절대치 평균 오차의 차이 𝜖 < 0.001 로 선택하였다. 잡음이 없는 경우는 Shepp-Logan 두부 팬텀을 이용하였고 잡음이 있는 경우는 Geant4를 이용하여 다양한 입사광자에 대해 360, 720, 1,440개의 투영을 얻었다. 정지 조건에서 10회 내외의 반복으로 우수한 단면 영상을 획득하였다. 수 백회 이상을 반복하는 최적 영상기반의 방법에 비해 현실적으로 적용 가능성이 높은 방법이 될 수 있을 것이다.

The purpose of this cross-sectional study was to explore fear of falling in relation to activity restriction of in the community dwelling elderly. Two hundred ninety-nine community dwelling elderly residing in Seoul and Kyonggi-do were interviewed using a structured questionnaire. The results were as follows : 1. Subjects were predominantly women$(70.6\%)$, an average 72.5 years old; the incidence of falls in last one year was $45.5\%$. 2. The highest level of fear found for activity in those who say they do engage and those who do not engage in the activity was 'going out when it is slippery '(m=2.53, 2.81) and 'reach for something over your head'(m=1.66, 2.60). Fear of falling scores were significant lower for those who say they do engage in eight kinds of activities (excluded activities of given were 'go to the store', 'take a tub bath', 'get out of bed') than for those who do not engage in the activities. 3. Among those who did not perform the activity, the three activities, when it is slippy(n=80), reaching overhead(n=70), and walk outside(n=59),were most often avoided because fear alone as well as for reasons in addition to fear. 4. The significant variables associated with fear of falling were female(p=0.0000), 1 educational status(p=0.000l), poor economic condition(p=0.0007), and experience of falls in last one year(p=0.0007). Fear of falling is common in the community dwelling elderly in Korea and is associated with several demographical variables. Therefore, to prevent falls and to reduce fear of falling, further study for development of education program for the elderly is needed.

We present preliminary results from a series of observations toward G108.8-00.8, which is one of Planck Cold Clumps and a promising candidate of massive prestellar cores. In the integrated intensity map of SCUBA 850 micron dust continuum emission, highly fragmented structures appear. These are distributed along one long filamentary structure seen in the CO 1-0 and 13CO 1-0 integrated intensity maps obtained with the PMO 13.7 m telescope. The northern part of the filament is divided into two parts, as seen in the CO 2-1, 13CO 2-1, and C18O 2-1 integrated intensity maps obtained with the CSO 10 m telescope. The observations of HCO+ 1-0, N2H+ 1-0, and HCN 1-0 with the IRAM 30 m telescope focus on the northern part of the CSO maps, which show a head-tail structure. NH3 (1,1) also shows similar distribution with IRAM maps. The depletion factors, derived by the comparison between the dust continuum and C18O 2-1 emission, varies from 1.5 to 6 over the region, suggesting different evolutionary status of each component. To study the chemical and physical environments of G108.8-00.8, more detailed analysis is in progress.
