본 논문에서는 현대 데이터 컨퍼런싱 분야에서 국제적인 표준으로 되어있는 T.120시리즈의 핵심 기술인 MCS를 멀티캐스트 수송계층 포르토콜 위에서 수행하기 위한 알고리듬을 제안하고 이에 따른 구현 구조를 기술하였다. 구현된 알고리즘은 기존의 MCS와 역방향 호환성을 유지하면서 새로운 멀티캐스트 수송계층의 기능을 충분히 이용할 수 있게 하였다. 이를 위하여 MCS의 연결설정 시에 상대의 수송계층이 멀티캐스트 기능을 가지고 있는 지를 조사하여 멀티캐스트 기능이 있다면 멀티캐스트 수송계층의 기능을 이용하고, 없다면 단일 수송계층을 이용하게 된다. 이러한 기술적인 내용에 대하여는 T.120 시리즈의 상호운용성 시험을 주관하는 IMTC에 기고될 예정이다.

Purpose : The purpose of this study was to investigate the effect of abdominal muscle strengthening exercise on abdominal muscle strength and respiratory function in stroke patients. Methods : The subjects were 14 stroke patients (10 males, 4 females) hospitalized at W rehabilitation hospital in Busan City and randomly assigned to 7 exercise groups and 7 control groups. Exercise was performed in combination with an upper and lower extremity pattern of proprioceptive neuromuscular facilitation. Measurements of abdominal muscle strength and respiratory function were made before intervention and 4 weeks after intervention. Abdominal muscle strength was assessed using a digital manual dynamometer, and respiratory function was assessed by spirometry. The collected data were analyzed with a paired t-test and independent t-test and the significance level was set as α =.05. Results : The results showed that applying abdominal muscle strengthening exercise to stroke patients showed a significant increase in abdominal muscle strength and a significant difference between groups (p<.05). Maximal-effort expiratory spirogram (MES) readings were significantly increased in forced vital capacity (FVC), and forced expiratory volume in one second (FEV₁), in the exercise group, and there were a significant differences between the groups in terms of FEV1 (p<.05). Slow vital capacity (SVC) was significantly increased in vital capacity (VC), tidal volume (TV), inspiratory reserve volume (IRV), and expiratory capacity (EC), and there were significant differences between the groups in VC, TV, expiratory reserve volume (ERV), EC, and inspiratory capacity (IC) (p<.05). Conclusion : Abdominal muscle strengthening exercise was effective in the abdominal muscle strength of stroke patients, and it was confirmed to have a positive effect on the enhancement of respiratory function. Therefore, it seems that exercise programs for stroke patients with respiratory weakness should include abdominal muscle strengthening exercises.

Rice (Oryza sativa L.) is the world's most important cereal crop. In crop plant, chlorophyll content and leaf senescence could affect grain filling and yield. We analyzed a QTL associated with chlorophyll content and delayed leaf senescence using high chlorophyll near isogenic line (HC-NIL). HC-NIL derived from a cross between Oryza sativa cv. Hwaseong as a recurrent parent and wild species O. grandiglumis as a donor parent showed higher chlorophyll content than Hwaseong. To identify QTL associated with chlorophyll content, 58 $F_3$ and 38 $F_4$ lines were developed from a cross between HC-NIL and Hwaseong. For QTL analysis, simple sequence repeat (SSR) markers were used for genotyping and one-way ANOVA was conducted. A QTL for chlorophyll content (qCC2) was detected in chromosome 2 and explained 24.63% of phenotypic variation. The senescence effect of the qCC2 was examined in dark-induced incubation (DII). Detached leaves from Hwaseong and HC-NIL were incubated on 3mM MES buffer (pH 5.8) at $27^{\circ}C$ under complete dark condition. After 3 days of incubation, the Hwaseong leaves turned yellow, but the HC-NIL leaves were green. HC-NIL has higher chlorophyll content with delayed senescence than Hwaseong. These results indicated that qCC2 is associated with stay-green phenotype. To know whether the qCC2 is responsible for leaf functionality, ion leakage test and Fv/Fm measurement were performed. Both experiment results showed that differences were observed between Hwaseong and HC-NIL but it was not statistically significant. These results might suggest that the qCC2 is possibly related to chlorophyll content and non-functional stay-green phenotype.

This paper proposes a new global positioning system (GPS) receiver algorithm to improve the positioning accuracy of a transporter using fault detection and isolation techniques from satellite signals. To improve the positioning accuracy, several factors including a feasible number of satellite signals, SNR, NAV Measurement Quality Indicator (mesQI), and Doppler, among others, have been utilized in the proposed algorithm. To increase the number of feasible satellite signals, an erroneous satellite signal has been replaced by the previous one. In conventional approaches, received GPS signals are analyzed and directly determined to be contaminated or not. The only clean signals are utilized for identifying the current location. This fault detection and isolation (FDI) feasibility test is popular for commercial GPS receivers. In the urban environment, especially near a building, the feasible number of satellite signals becomes insufficient to position the transporter. To overcome this problem, satellite signals are efficiently selected and recovered. Additionally, using the proposed GPS receiver algorithm, a feasible number of satellite signals can be increased, thereby improving the positional accuracy. Real world experiments using a transporter that carries blocks in a shipyard have demonstrated the superiority of the proposed algorithm compared to conventional approaches.

Objectives : The aims of this report are to examine the personal characteristics and to determine the different reactions against stress by constitutions. To achieve these goals, the statistical research was adopted. Methods : First of all, the total numbers of 398 middle school students were classified into three constitutions by QSCC II. According to each type of constitutions, both of the KPI Personality Test and Multidimensional Encountering Scale (MES) on how to deal with stress were conducted. Summary of the findings : 1. Based on the findings assessed by the QSCC II test, the constitutional distribution reveals the difference according to genders. In Chi-square test, the girl reveals significantly high (p<0.05) distribution in Soyangin. 2. In Independent T-test regarding KPI personality, the girl reveals high significance (p<0.05) in terms of 'Sociability', 'Responsibility', 'Synchronism' and 'Self-feminity' (or Feminization) while the boy reveals high significance in 'Goal-driven' (p<0.05). 3. In Independent T-test regarding the multidimensional encounter scaling, the girl reveals high significance (p<0.05) in D (expression of emotion). 4. In case of the boy, the Soeumin shows low significance (p<0.05) in 'Leadership' and 'Sociability' compared to the Taeumin or the Soyangin. On the other hand, the Soeumin reveals high significance (p<0.05) in 'Responsibility' and 'Self-control' compared to the Soyangin and additionally, shows high significance (p<0.05) in 'Self-feminity' (or Feminization) compared to the Taeumin or the Soyangin. Furthermore, the Soyangin shows high significance (p<0.05) in 'Self-confidence' compared to the Soeumin or the Taeumin. 5. In case of the girl, the Soyangin reveals high significance in 'Sociability' and 'Self-confidence' compared to the Soeumin or the Taeumin while the Soeumin has high significance in 'Synchronism' compared to the Taeumin or Soyangin. On the other hand, the Soeumin has high significance in terms of 'Responsibility', 'Self-control', and 'Self-feminity' (or Feminization) while showing low significance in 'Flexibility' compared to the Soyangin. 6. For boys, the Soeumin has low significance in 'Sociability' in comparison with both the Soyangin and the Taeumin, whereas for girls, the Soyangin reveals high significance in 'Sociability' in comparison with both the Soeumin and the Taeumin. As per the 'Self-confidence' and 'Responsibility', it has been proved that there is no notable difference between the boy and the girl, but to the contrary, as per the 'Self-confidence', both for the girl and the boy, the Soyangin has high significance (p<0.05) in comparison with the Soeumin and the Taeumin. In addition, in 'Responsibility' side, it is recognized that the Soeumin shows high significance (p<0.05) in comparison with the Soyangin both for boys and girls. Only the difference between genders, as to the 'Self-confidence', is that the Soeumin shows low distribution compared to the Taeumin in the case of boys, while the Taeumin shows low distribution compared to the Soeumin in the case of girls. In 'Self-feminity' (or Feminization), for boys the Soeumin shows high significance in comparison with both the Soeumin and the Taeumin, but to the contrary, for girls the Soeumin shows high significance (p<0.05) only against the Soyangin. 7. In case of boys, as to 'Conformability (compromise)', the Taeumin compared to the Soeumin reveals high significance (p<0.05), while for girls, the Soeumin compared to the Soyangin or the Taeumin reveals high significance (p<0.05). Consequently, it presents that the Soyangin has a tendency not to confirm (compromise) relatively in comparison with other constitutions regardless of the genders. Conclusions : In general, except that it shows some constitutional deviation by genders, the statistical findings of this report agree and comply with the personal characteristics of Sasangin presented by Je-Ma Lee.

목적 : HBV 감염과 연관된 신병증의임상 및 검사소견과 병리학적 소견을 분석하여 그 특징을 규명하고, HBeAg과 HBsAg에 대한 면역조직화학염색을 신생검조직에서 시행하여 이들 항원의 사구체내에서의 면역학적 발현을 관찰하므로써 이 질환의 발생 기전에 대한 이해를 돕고자하였다. 방법 : 1990년 4월부터 1997년 2월까지 사구체신염으로 신조직 생검을 시행하여 부산백병원 해부병리과에 병리조직검사가 의뢰된 증례 중 혈청 HBsAg 양성인 28례를 대상으로 임상 및 검사소견을 조사하였고, 신조직의 광학현미경적, 면역형광학적, 전자현미경적 검사와 HBsAg과 HBeAg 항원에 대한 면역조직화학검사를 시행하였다. 결과 : 1. 연령 분포는 6세에서 73세였으며 소아 환자가 8명이었고 성인 환자는 20명 이었다. 평균 연령은 28세였고, 남녀 비는 3:1 이었다. 내원당시 67.9%에서 혈뇨, 75.0%에서 단백뇨를 보였고 57.2%에서 신증후군을 나타내었다. 전 예에서 혈청 HBsAg이 양성이었고, 혈청 HBeAg은 검사가 시행된 9례 중 6례 (66.6%)에서 양성이었다. 2. 간기능검사가 시행된 11례 중 7례 (63.6%)에서 AST와 ALT치가 증가되어 있었으며, 이중 간생검이 시행된 3례 모두 만성 활동성 간염으로 진단되었다. 3. 28례 중 막성 사구체 신염 (membranous glomerulonephritis: MGN)이 10례 (35.7%)로 가장 많았으며, 메산지움중식성 사구체신염 (mesangioproliferative glomerulonephritis: MesGN)이 8례 (28.6%), 막증식성 사구체 신염 (membranoproliferaive glomerulonephritis : MPGN)은 7례 (25.0%) 그리고 미세변화질환 (minimal change disease : MCD)가 3nl (10.7%)순이었다. 4. HBV와 연관된 MGN에서는 혈관간 세포의 증식 및 혈관간 기질의 확장이 자주 관찰되었으며, 사구체간질 내와 내피하 침윤도 동반되어 MPGN을 시사하는 소견이 함께 관찰되는 예가 많았고, HBV 항원 혈증에 동반된 MPGN에서는 내피하 침윤 뿐 아니라 기저막 내 및 상피세포하 침윤도 종종 관찰되었다. 5. 신조직의 면역조직화학검사상 HBsAg은 모두 음성이었으나 HBeAg은 28례 중 8례 (28.6%)에서 사구체 모세혈관벽을 따라 양성 반응을 나타내었고, 이 중 3례는 혈치 HBeAg 검사를 받았는데 모두 양성이었다. 결론 : HBV와 연관된 사구체신염은 다양한 병리학적 양상을 보여주며, 특히 MGN과 MPGN에서는 전자현미경소견상 두 질환의 특징이 중복되어 나타났고, 사구체내에서 HBeAg이 검출되어 HBV의 활동성 정도와 사구체신염의 발생이 연관성이 있을 것으로 사료되나 더 많은 연구보고가 있어야 하겠다.

논벼농사의 노동력을 덜기 위하여 이중 가장 중요한 호미질에 의한 중경제초의 노력을 살초제에 의한 것으로 전환시키고자 기초적인 면과 실제적인 면으로 시험조사를 하였다. 건국대학교에서 1m평방 안높이 21cm 및 36cm의 두 형의 concrete tank를 각 4개씩 만들고 그 안에 채수관장치를 한 뒤 양토작토로 논벼를 심어 수도물로 관수하고 투수속도와 산소침투 정도와 수량과의 관계를 보았다. 농림부 자재 검사소 내에서 투수가 심한 사질답전포장에 전면적으로 살초제 Stam F-34를 살포하여 제초하고 제 1구는 중경을 하지 않고, 제 2구는 중경 1회, 그리고 제 3구는 중경 2회하여 중경의 효과를 비교하였다. 이리 호남시험장내 건답보통논과 습답에 무중경, 중경 1회 중경 2회의 구와 살초제 Pamcon을 살포한 것들 중, 무중경, 중경 1회 제초 2회, 중경 2회 제초 1회, 중경 3회 제초 2회의 구와 그리고 관행구를 설치하여 중경제초의 비용과 살초제에 의한 비용을 비교하였던바 그 결과를 요약하면 다음과 같다. (1) 투수속도와 산소침투와 수량과의 관계는 일당(24시간당) 투수속도 4cm이상 될 때 지표 2cm하에 산소가 조금 들어가며 3cm보다 적을 때는 산소가 지표하의 매우 옅은 층에만 내려가는 것으로 나타나며 그리고 경심 15cm구에는 일당 투수속도의 0cm(무투수) 1.5cm에서 수량이 많고 2.5cm와 3.4cm에는 감수되며, 경심 30cm구에는 투수속도 1.5cm 및 30cm구에서 수량이 많고 무투수와 투수속도 4cm구에는 수량이 떨어졌다. (2) 투수가 심한 농림부 자재검사소 사질토양에서는 중경의 효과가 없었다. (3) 호남작물시험장내 건답에서는 살초제 Pamcon 처리 무중경구 수량에 대해서 유의성이 보이는 증수구는 없었다. 그리고 습답에서는 무중경구에 있어서 중경제초 및 관행구가 유의성 있게 증수되었다. (4) 논매기 호미질에 의한 10a당 노동력은 정미 37.1시간 식사와 휴식시간 포함하여 53.5시간이고, 노임은 2,346원인데 대하여 살초제 사용에의 한제 초노력은 수동식으로 0.5일 즉 약 5시간 제비용과 감수추정량을 추정할 때 1,130원이고 습답을 제외하면 750원이 되는 것으로 추정 되었다.
