박종호,정영근,김경호,박태일,김양길,강천식,윤영미,손재한,이석하,Park, Jong-Ho,Cheong, Young-Keun,Kim, Kyong-Ho,Park, Tae-Il,Kim, Yang-Kil,Kang, Chon-Sik,Yoon, Young-Mi,Son, Jae-Han,Lee, Suk-Ha 한국초지조사료학회 2018 한국초지조사료학회지 Vol.38 No.2

This study aimed to determine the optimal harvesting time for wheat to make grain silage, in Honam region of Korea. We harvested wheat grain every third day from 30 to 42 days after heading (DAH). The moisture content decreased from 61.6% at 30 DAH to 42.8% at 42 DAH. Yield of wheat grain significantly increased from 30 to 42 DAH (p< 0.05). Yield at 39 DAH (3.46T/ha) was not significantly different from that at 42 DAH (p< 0.05). With respect to the feed value of wheat grain silage, the amount of crude protein, crude fiber, and crude ash was different by harvesting time (p< 0.05). However, the amount of total digestible nutrients (TDN) from 30 and 42 DAH was not significantly different. The pH of wheat grain silage from 30 to 42 DAH was between 3.8 and 4.5 and it was stable until 39 DAH (p< 0.05). The lactic acid content of wheat grain silage from 30 to 42 DAH decreased from 3.08% to 1.10%. With respect to moisture content, yield, feed value, and fermentation, the optimal harvesting time for wheat grain silage was 39 DAH. 출수 후 수확일수에 따라 수량 및 사료가치를 고려해 보면 밀 수량은 출수 후 30일부터 42일까지 유의적으로 증가하였으며(p<0.05), 최대 수량은 42일차에 5.57T/ha이었는데, 39일, 42일차와는 유의적 차이를 보이지 않았다. 사료가치의 경우 조단백, 조섬유, 조회분의 경우 유의적 차이를 보이나, 조지방, TDN의 경우 유의적 차이를 보이지 않았다(p<0.05). 발효에 영향을 주는 pH는 30일부터 39일까지는 pH 3.8-4.2까지 안정을 유지하다가 42일차부터는 pH4.5로 증가하여 일부 품종의 경우 발효에 적합하지 않았다(p<0.05). 따라서 밀의 곡실 발효사료 제조를 위한 최적 수확시기는 출수 후 39일차였다.

박종호,문정석,이우천,배우한,서정국,Park, Jong-Ho,Moon, Jeong-Seok,Lee, Woo-Chun,Bae, Woo-Han,Seo, Jeong-Gook 대한족부족관절학회 2009 대한족부족관절학회지 Vol.13 No.2

Purpose: To evaluate the short-term results of medial displacement calcaneal osteotomy without flexor digitorum longus transfer for flexible flatfoot deformity. Materials and Methods: Twenty four patients (25 feet) who had undergone medial displacement calcaneal osteotomy without flexor digitorum longus transfer for flexible flatfoot between July 2004 and May 2007 were included. The mean age was 43.6 years (16~78 years). The mean follow-up was 26 months (14~50 months). Clinical outcomes were assessed using American Orthopaedic Foot and Ankle Society (AOFAS) score and visual analogue scale (VAS). Six radiographic parameters were measured from weightbearing radiographs to assess the difference between preoperative and postoperative radiographs. Results: The mean AOFAS score improved from 57.9 points preoperatively to 89.2 points at latest follow-up (p=0.000). The mean VAS improved from 62 points preoperatively to 23 points at latest follow-up (p=0.000). The mean talonavicular coverage angle on anteroposterior (AP) view changed from 20.2 degrees to 16.0 degrees (p=0.002). The mean calcaneal pitch angle on lateral view changed from 12.6 degrees preoperatively to 14.5 degrees at latest follow-up (p=0.001). Regarding these radiographic parameters, the difference between interobserver measurements was larger than that between pre- and post-operative measurements. The calcaneus was transferred medially by average 11.8 mm (p=0.003), which was 27.9% of the width of calcaneal tuberosity (p=0.000). The mean talo-first metatarsal angle on AP and lateral views, and navicular height on lateral view were not significantly changed. Conclusion: Medial displacement calcaneal osteotomy without flexor digitorum longus transfer for flexible flatfoot could lead to improve the clinical outcomes, although the restoration of medial longitudinal arch was not clinically significant.

KOINONIA는 고속 무선개인네트워크(Wireless Personal Area Network: WPAN) 기술로 개인 영역에서 고속의 데이터 전송과 멀티미디어 트래픽 전송을 지원하기 위해 개발되었다. 마스터와 슬레이브가 스타 토폴로지 형태로 피코넷을 구성한다. 멀티미디어 트래픽의 QoS를 위해 마스터가 슬레이브의 요청을 받아 채널을 할당해주는 TDMA방식의 매체 접근 방법을 사용하는데, 이때 마스터가 각 할당요청에 대해 스케줄링을 하는 방법이 네크워크 전체의 성능에 크게 영향을 끼치게 된다. 따라서 채널을 효율적으로 사용하고 멀티미디어 트래픽의 QoS를 효과적으로 보장하기 위해서는 효율적인 채널 할당 스케줄링 알고리즘이 필요하다. 본 논문에서는 슈퍼프레임의 길이와 관계없이 일정 간격으로 채널 타임을 할당할 수 있는 스케줄링 및 CAC(Connection Admission Control) 알고리즘을 제안하고 시뮬레이션을 통해 채널 사용과 QoS 측면에서 효과적임을 보였다. 또한 제안한 알고리즘은 기본적인 스케줄링 기법인 WRR(Weighted Round-Robin)에 비해 데이터 특성에 맞게 채널 타임을 할당하므로 채널타임 절약과 더불어 전력소비도 절약할 수 있다. KOINONIA is high-rate Wireless Personal Area Network (WPAN) technology, and is developed for multimedia traffic transmission in personal area. A KOINONIA piconet is a collection of one or more associated slaves under a single master. Efficient scheduling of a master for the traffic of slaves is essential to use channel effectively and to guarantee QoS of multimedia traffic. We propose a new scheduling algorithm to allocate channel time at desired intervals regardless of superframe length, and a Connection Admission Control(CAC) algorithm to regulate the number of traffics in a piconet. Our proposed algorithms have been shown to save channel time and to meet QoS requirements compared to the conventional weighted round-robin algorithm.

Purpose: To investigate complication rates and results of cataract surgery in a monocular patient compared to normal binocular cataract patients. Methods: We retrospectively analyzed 84 eyes of 84 patients that had undergone phacoemulsification, intraocular lens implantation and were followed up for 6 months or more. The fellow eye condition was classified into two different groups: Group A (experimental group) and Group B (control group). The best corrected visual acuity (BCVA) before and after surgery, operation time, nucleus sclerosis, and complication rate between the two groups were compared. Results: Both groups showed a significant level of visual improvement after 6 months (p < 0.01, 0.01). There was no significant difference in sex, age, preoperative lens opacity, pre- and postoperative visual acuity, spherical equivalent, astigmatism, and rate of complications (posterior capsule rupture [n = 1], uveitis [n = 1] vs. posterior capsule rupture [n = 3], intraocular lens capture [n = 1]. Conclusions: The present study showed no difference in surgical results between Groups A and B. The results demonstrated that cataract surgery in a monocular patient resulted in favorable visual improvement.

박종호,박표원,Park, Jong-Ho,Park, Pyo-Won 대한흉부심장혈관외과학회 1991 Journal of Chest Surgery (J Chest Surg) Vol.24 No.6

Recently, cardiac injury due to blunt thoracic trauma appears to be increasing in frequency. The rising incidence of this mishap may relate to the absolute increase in automobile accidents as well as to more universal recognition that cardiac damage may have been sustained. We have experienced a rare case of ventricular septal defect caused by non-penetrating thoracic trauma. Of further interest is the history of chest trauma, clearly resulting in rupture of the chordae tendineae of the tricuspid valve successfully treated by operation-re-placement with two, 6 - 0, double-armed, expanded polytetrafluoroethylene sutures-2 months later. The unique combination of ventricular septal defect and rupture of the chordae tendineae of the tricuspid valve secondary to non-penetrating thoracic trauma is presented below to emphasize another variety of cardiac injury.

Purpose: To report a case of suprasellar arachnoid cyst with compressive optic neuropathy. Case summary: A 50-year-old man presented with decreased visual acuity in the right eye of 6 months duration. Best corrected visual acuity was 0.2 in the right eye, 1.0 in the left eye, and the intraocular pressure was 13 mm Hg in the right eye, and 18 mm Hg in the left eye. Fundus examination showed pale optic disc in the right eye and retinal nerve fiber layer defects in both eyes. Visual field examination revealed a central visual field of 10° in the right eye and an inferior visual field defect in the left eye. The brain magnetic resonance image (MRI) showed a suprasellar arachnoid cyst that compressing the optic nerve and chiasm. Conclusions: The author experienced arachnoid cyst accompanied by optic disc atrophy and visual field defect in a patient diagnosed and treated for glaucoma. In cases of non-specific clinical features that differ from typical glaucomatous presentations, the utilization of brain MRI appears to be helpful in diagnosis and treatment.
