낭종성 부갑상선 선종과 심한 골병변을 동반한 부갑상선 기능항진증은 매우 드문 질환으로서, 저자들은 양측 고관절의 통증을 초기 주소로 내원한 환자에서 고칼슘혈증과 부갑상선 호르몬 증가, 골병변의 방사선적 소견을 통해 부갑상선 기능항진증을 진단하고, 경부 초음파와 컴퓨터 단층 촬영, 부갑상선 스캔검사 및 수술중 부갑상선 낭종액 검사 등을 통해 기능성 부갑상선 낭종의 한 종류인 낭종성 부갑상선 선종을 진단하고 수술적 제거를 통하여 정상화된 1예를 경험하였다. A cystic parathyroid adenoma is rare. A case of primary hyperparathyroidism, with the cystic formation of a parathyroid adenoma and a severe bony lesion, is reported. A 52-year-old male was admitted due to pain in both hips and for evaluation of hypercalcemia. The plasma level of the intact parathyroid hormone (iPTH) was elevated to 1424 pg/mL. Ultrasonography and the computed tomography revealed a parathyroid cyst on the left thyroid lower pole. Parathyroid scintigraphy detected a parathyroid adenoma. A radiograph showed a subperiosteal bone resorption on the phalanges, and a brown tumor (osteitis fibrosa cystica) on the femur shaft was noted. A surgical excision of the parathyroid adenoma was performed. The PTH level in the cystic fluid was increased. A histological examination confirmed a cystic parathyroid adenoma. The PTH level was normalized after the operation (J Kor SOC Endocrinol 18:214-220, 2003).

The purpose of this paper is to verify if a protocol implementation conforms to its specification, CCITT No. 7 SCCP. Protocol implementation have to be tested in a manner reflecting most closely a normal operating environment. This implies that the protocol entity must be tested as "black box". Communication protocol can be modeled by a finite state machine with is 1) completely specified, 2) minimal, and 3) strongly connected. This paper is focused on the methods for generating test sequences for communication protocol, considering in particular their effective-ness in detecting possible errors, and their effieciency measured by the length of the test sequence.

잣나무 苗木의 養苗法 改善에 關한 硏究 Ⅲ : 播種時期이 差에 따른 잣나무 幼苗의 生長 比較 Effects of seeding time on the growth of young seedling

After hastening seed germination by means of open ground storage during the period from the fall to next year spring, the growthes of seedlings seeded at different days were compared. The results obtained were summarized as follows: 1. The effects of seeding time on the length, diameter and weight growth of seedlings were irregular. However, each of the maximum growthes appeared on the 26th and 30th of March. Comparatively, the early seeding, the last ten days of March, was favorable for young seedling growth. 2. The contribution rates to the length, diameter, and weight growth by seeding time was 32.9%, 8.8% and 60.9%. The weight growth of seedlings was especially effected by seeding time.

Computer system designers and system integrators producing leading edge equipment in the future will often opt powerfull microprocessors, or microprocessor based boards and systems. They must hook these chips and boards together with a flexible bus if they wants take a full advantage of system functionality. To help make an intelligent decision as to which bus to choose for a computer system's lifetime, designers should be cognizant of major and minor differences between the buses. Today, there are two major open buse choices-Multibus Ⅱ and VME bus. In addition, there is a 32bit bus standard from the IEEE. So, in this paper we analyse and compare the characteristics of buses-VME bus, multibus Ⅱ and P.896 bus.

Global Register Allocation plays a major role in determining efficacy of Optimizing Compilers. Instructions involving only register operands are shorter and faster than those involving memory operands. Therefore, efficient utilization of limited number of hardware registers is important in generation good code. Register allocator attempts to map registers in such a way as to minimize the number of memory references. In this paper, we compare several register allocation methods and have designed and implemented a global register allocator using priority-based graph coloring.

In these days, as rapid growth of multimedia industries and development of techniques, an effort to develop DAVIC(Digital Audio-Visual Council) systems which support multimedia services such as VOD(Video on Demand) and teleshopping is being done. Therefore it will be indispensable to establish a new conformance testing method related DAVIC system with respect to their standard specification. DSM-CC is a core part of DAVIC and adopts DSM-CC U-N for S3 information stream which plays a part in connection establishment and release of session and transmission layer, and DSM-CC U-U for S2 which operates user application of the system. In this paper, we propose a new conformance testing architecture and methodology based on scenario in order to test DSM-CC U-U which doesn't have any message sequences.

The interconnection network is an integral part of multiprocessing system. The multistage interconnection network(MINs) have been the objects of intense research in recent years. In this paper, the performance of circuit swiching MINs is investigated with new conflict resolution strategies. The timeout(t) control resolution model, proposed by this paper, includes drop and hold strategies, and it is shown that the results of performance evaluation for circuit switching generalized cube networks are analysed by timeout(t) strategy. The results of performance evaluation of partitioned MINs indicate that "input partitioning" coupled with the used of the "large t for timeout(t)" strategy produces the best network operation in terms of RST(Requst Service Time).

The purpose of this trudy is to describe and analyze the Kendo deucation classes at the University by the means of ethnographic research method. The field work for this study was conducted by the researcher from March., 2004 to May., 2004 at the University. Instead of drawing specific conclusion of the study, the problems which appeared in real physical education classes are desrbled here. 1) Kendo education Professor tends to adhere to traditiona (existing) teaching contents and methods rather than inquire or research on the contents of his classes. 2) Students usually recognize that Kendo education is the same as mental practice, control exercise, or Beautiful sport. 3) Professor's feedbacks are given 2,3 times per minute during students' practice period, and the learning climate becomes positive. 4) Professor's feedbacks are given concentratively to students who are lacking in task performing ability or are disturbing their classes, rather than to all students. 5) In many cases, teaching methods make the situations in which control are needed.

잣나무의 몇개 葉形質에 미치는 光度의 影響

全尙根,金英彩 慶熙大學校 1983 論文集 Vol.12 No.-

In the seedling grown under different light internsities for two years at seed bed, length of needle, density of serration, number of stomata and stomatal zone, and number of endodermal call in needle varied with relative light intensity except number of secretory cell. And the leaf characters were influenced by the light intensity in contribution rates from 18.4% to 34.3%. Positive correlation between the growth and weight of seedlings and the leaf characters were recognized. But there were no significant correlations between the growth of seedling and number of serration, and between the weight of seedling and density of stomata and serration.
