본 연구에서는 게임 내 NPC 내러티브를 효율적으로 생성하는 시스템을 대형 언어 모델(LLM) 기술을 활용하여 제안했다. 자연스럽고 일관된 NPC 서사 생성을 위해 세 가지 (기본 프롬프트, 정보 프롬프트, 변수 프롬프트)로 구성된 프롬프트 설계 방법론을 개발하였다. 이는 기존의 수작업 중심 NPC 설계 방식에 비해 개발 효율성과 NPC 다양성을 크게 향상시킨다. 게임 업계 종사자 48명을 대상으로 실시한 평가에서 자연스러움은 평균 4.35점, 완성도는 평균 4.06점으로 높게 나타났으며, 평가자의 62.5%가 실제 게임 개발에 도입할 의향이 있다고 응답했다. 두 평가 항목 사이에는 강한 양의 상관관계(r=0.813, p=0.05)가 확인되었다. 연구 결과는 LLM 기반 NPC 생성 기술이 게임의 몰입감을 향상시키고 플레이어 참여도를 증진시킬 수 있음을 시사한다. 향후 연구 방향으로는 NPC의 대화 생성 시스템 및 외형 생성과의 연계 연구가 필요할 것으로 제안된다. This study proposes a system for efficiently generating in-game NPC narratives using large language model (LLM) technology. To create natural and consistent NPC narratives, we developed a prompt design methodology consisting of three components: basic prompts, information prompts, and variable prompts. This approach significantly improves development efficiency and NPC diversity compared to traditional manual NPC design methods. In an evaluation conducted with 48 game industry professionals, naturalness scored an average of 4.35 and completeness scored an average of 4.06, both indicating high satisfaction. Additionally, 62.5% of evaluators expressed an intention to adopt the system in actual game development. A strong positive correlation (r=0.813, p=0.05) was observed between the two evaluation metrics. The research results suggest that LLM-based NPC generation technology can enhance immersion in games and increase player engagement. Future research directions include studying the integration of NPC dialogue generation systems with appearance generation.

Purpose: Calcaneal lengthening osteotomy is one option for the treatment of symptomatic flexible flatfoot in adults. The aim of the study was to evaluate the short term clinical and radiologic results and analyze its complications. Materials and Methods: Twelve feet who had undergone calcaneal lengthening osteotomy without flexor digitorum longus transfer between December 2009 and July 2011 were included. The mean age was 40.6 years (23~75 years). The mean followup was 17.3 months (13~25 months). Clinical outcome were assessed using American Orthopadics Foot ans Ankle Society (AOFAS) score and visual analogue scale (VAS) for pain. Four radiologic parameters were measured from weightbearing radiographs to evaluate the difference between preoperatively and postoperatively measures. To analyze the complications, calcaneocuboid joint subluxation and degenerative change were measured postoperatively. Results: The mean AOFAS score improved from 55.3 points preoperatively to 82.2 points at lastest follow-up (p=0.000). The mean VAS improved from 6.3 points preoperatively to 3.2 points postoperatively (p=0.002).All radiologic parameters, the mean talonavicular coverage angle on AP view, the mean talo-1st metatarsal angle on AP and lateral view and the mean calcaneal pitch angle, significantly improved after calcaneal lengthening osteotomy. Nine feets (75%) were shown the degenerative change in the calcaneocuboid joint at latest follow-up radiographs. Conclusion: Calcaneal lengthening osteotomy for the symptomatic flexible flatfoot in adults produced significant improvement in clinical and radiologic parameters, but calcaneocuboid joint osteoarthritis occurred postoperatively remained a major problem.

Purpose: To evaluate the radiographic characteristics of the tarsometatarsal osteoarthritis with hallux valgus deformity and report the clinical results of the operative treatment. Materials and Methods: This is a retrospective study of 20 patients, 22 feet who had been operated for non-traumatic tarsometatarsal osteoarthritis with hallux valgus (TMT group) and control group of hallux valgus patients without tarsometatarsal osteoarthritis (26 patients, 28 feet) from April 2004 to July 2011. Radiographic characteristics were compared between the groups, using hallux valgus angle, $1^{st}-2^{nd}$ intermetatarsal angle, metatarsal length ratio, metatarsus adductus angle, talonavicular coverage angle, talus-$1^{st}$ metatarsal angle, calcaneal pitch angle and medial cuneiform height. Pre- and postoperative difference of $1^{st}-2^{nd}$ metatarsal declination angle and distance between the $1^{st}-2^{nd}$ metatarsal head were evaluated. The clinical results were evaluated by American Orthopaedics Foot and Ankle Society (AOFAS) midfoot scale and visual analogue scale (VAS). Results: Metatarsal length ratio was significantly larger in TMT group (p<0.001). Metatarsus adductus angle, talonavicular coverage angle, talus-$1^{st}$ metatarsal angle on lateral radiograph, calcaneal pitch angle and medial cuneiform height were different from control group (p<0.001, p<0.001, p=0.001, p=0.010, p=0.006). Postoperative declination of the $2^{nd}$ metatarsal and distance between the $1^{st}-2^{nd}$ metatarsal head were increased (p=0.009, p=0.001). The AOFAS and VAS score were improved (p<0.001, p<0.001). Conclusion: Non-traumatic osteoarthritis of the tarsometatarsal joints seems to be associated with long 2nd metatarsal length, metatarsus adductus and flatfoot deformity. Spur excision may be successful to relieve symptoms when the arthritis was diagnosed in early stage.

그래픽 처리 장치 성능에 대한 메모리 구조의 영향 평가

GPU들은 다수의 병렬 연산 처리장치를 가지고 있기 때문에 높은 병렬성을 보여준다. 뛰어난 연산 자원을 활용하기 위해 서 최신 GPU들을 범용 응용프로그램에 활용하는 GPGPU 기술이 개발되었다. 하지만 GPU가 높은 연산 처리 능력을 가지 고 있음에도 불구하고, 메모리 자원의 제한으로 인해 최대 성능을 보여주지 못한다. 그러므로 GPU의 장점을 충분히 활용 하기 위해서는 뛰어난 성능의 메모리 구조가 필요하다. 본 논문에서는 뛰어난 성능의 메모리 구조를 개발하기 위한 연구의 당위성을 보이기 위해서, 이상적인 메모리 구조를 가진 GPU가 일반적인 메모리 구조를 가진 GPU에 비해 월등히 나은 성 능을 보이는 것을 정량적으로 측정하여 보여주고자 한다. 실험 결과에 따르면, 이상적인 메모리 구조를 가진 GPU는 일반 적인 메모리 구조를 가진 GPU에 비해 높은 성능을 보인다. 뿐만 아니라, 실험 결과는 응용프로그램에 따라 성능 향상 폭 이 상이한 것도 보여주고 있다. Recent Graphics Processing Units(GPUs) have many computational resources to provide high parallelism. Moreover, GPUs can execute general purpose applications to exploit high computational power. However, a GPU does not accomplish peak performance due to limited memory system even though a GPU has high throughput. Therefore, memory architecture providing high performance should be supported. In this paper, we show that the performance of the GPU with ideal memory system is much higher than the performance of the GPU with conventional memory system which indicates the effects of limited memory resources in order to prove that studying memory system on the GPU is very important. According to our simulation results, the GPU with ideal memory system shows better performance than the GPU with conventional memory system. Moreover, experimental results also show the performance depending on benchmarks. Therefore, characteristics of applications should be considered for the research focusing on the performance of memory system on the GPU.

The Effectiveness of Plantar Aponeurosis Release for the Limitation in First Metatarsophalangeal Joint Extension after Hallux Valgus Surgery

최홍준,김대욱,강영훈,박종호,손찬모,Choi, Hong-Joon,Kim, Dae-Wook,Kang, Yeong-Hun,Park, Jong-Ho,Son, Chan-Mo Korean FootAnkle Society 2017 대한족부족관절학회지 Vol.21 No.2

Purpose: Stiffness in the first metatarsophalangeal joint after surgery for hallux valgus has been reported. The goal of this study was to test the efficacy of releasing plantar aponeurosis for improving the range of extension in the first metatarsophalangeal joint that was limited after hallux valgus surgery. Materials and Methods: Thirteen patients (1 man, 12 women [17 feet]; median age, 54.4 years; range, 44~69 years) with limited first metatarsophalangeal joint extension after hallux valgus surgery, who underwent an additional procedure of plantar aponeurosis release between March 2015 and August 2015, were included. Subsequently, the passive range of extension in the first metatarsophalangeal joint was evaluated via knee extension and flexion positions. Hallux valgus angle, inter-metatarsal angle, distal metatarsal articular angle, and talo-first metatarsal angle were measured on weightbearing dorsoplantar and lateral radiographs of the foot preoperatively. Results: The mean range of extension for the first metatarsophalangeal joint improved significantly, from $2.5^{\circ}$ to $40.9^{\circ}$ in the knee extension position (p<0.00). The mean extension range for the first metatarsophalangeal joint also improved, from $18.2^{\circ}$ to $43.2^{\circ}$ in the knee flexion position (p<0.00). In all patients, congruence of the first metatarsophalangeal joint was recovered. Conclusion: Plantar aponeurosis release is an effective additional procedure for improving the extension range of the first metatarsophalangeal joint after hallux valgus surgery.
