This study considers the stages of curriculum development for the integrated curriculum of Pusan National University Graduate School & Hospital of Korean Medicine, and specifically the KAS2021 (announced in 2019), improvement measures for the curriculum of the College of Traditional Korean Medicine, and the case of the College of Medicine. The introduction of integrated curriculum in the College of Traditional Korean Medicine starts from the members (doers)' agreement. In the process of development, the organization that represents the members, the organization that sets up a goal and designs the curriculum, and the organization that executes them should fulfill their own roles. The stage of development and operation should have the support system for manpower, institution, administration, and finance. The curriculum (draft) should be concrete enough to be operated in reality. For the smooth operation of integrated education, it is necessary to secure more full-time teachers than before, and it is also necessary to have an organization fully in charge of monitoring and improving the operation. For the introduction and operation of integrated curriculum in Traditional Korean Medicine education, the members' agreement, institutional change, support system, and the cultivation of manpower for the operation/evaluation/development of curriculum should be considered.

This study starts from the architectural and urban interest to integrate the daily life and behavior of residents in the city of Seongnam and to sustain the community. A fixed abode is something that can not be separated from the place and should be approached from a comprehensive perspective reflecting the physical and social conditions of the region. Although residential neighborhoods have a residential walking range, which has a steep slope, it has been formed in the suburbs of the residential area where commercial facilities are activated organically. The humanities and social organizations of the residents are integrated with the physical space and act as constituent factors of major cities. This is an attempt to suggest improvement and activation of existing cities based on their daily lives, rather than destroying cities and creating new ones. Also, it is proposed to 'Neighborhood Street' as an indicator of a uniform urban renewal plan for existing urban regeneration projects. Based on the definition of the city of living in the city, the center of the city will be located in the center of the city, and it will be the center of the city's bustling streets.

Social innovation refers to activities that solve social problems by developing new ideas in cooperation with actors close to the field for the purpose of preserving the sustainability of society. In the field of social innovation, voices calling for a bottom-up method that starts with citizen participation are growing, and the need to improve public officials' awareness of social innovation and strengthen professionalism is being raised. In the era of Covid 19 and the 4th industrial revolution, digital literacy is being emphasized to us. In the field of social innovation, the need to strengthen social activities using digital media is growing. In this paper, an example of online social innovation project education based on the design thinking methodology was presented for public officials in Busan to improve their awareness of social innovation and secure expertise, and the effect of job competency reinforcement was statistically verified. As a result of statistical analysis, the average difference between the 'online communication' factor and the 'online empathy' factor was the largest, and it can be interpreted that digital literacy for social innovation has been strengthened.

Objectives: Sciatica is a musculoskeletal pain sensed in the leg along with the distribution of the sciatic nerve, which is sometimes accompanied by low back pain and is most commonly caused by a disc herniation. In the Unani system of Medicine, Irq-un-Nasa (Sciatica) is defined as the pain which starts from the hip joint and descends towards the foot. It is a type of Waja-ul-Mafasil which is developed due to the accumulation of Khilt-e-Dam or Khilt-e-Balgham ghaleez in the hip joint. The conventional system of Medicine offers several medications and surgeries to manage sciatica with limited clinical evidence of effectiveness. These cases aim to provide insight into the effects of Fasd (Venesection) in Irq-un-Nasa. Case Presentation: Fasd was performed in the saphena minor vein of two clinically diagnosed patients with sciatica after the initial assessment. Two sittings of Fasd, once a week in each patient, were performed, followed by telephonic assessments for two months. The intensity of sciatic pain reduced with subsequent sittings of Fasd, and there was no recurrence of any symptoms and signs again during complete follow-up. Conclusion: Based on the results of the present case report, it appears that such cases of Irq-un-Nasa can be managed with Fasd, and the quality of life of such patients can also be improved.

본 논문에서는 멀티코어 프로세서 및 매니코어 프로세서에서의 스캐터 통신 성능을 최대화 하기 위하여 프로세싱 노드의 통신채널 상태를 고려하는 기법을 32개 코어로 구성된 멀티코어 프로세서에 적용하였다. 기존의 스캐터 알고리즘은 프로세싱 노드들의 통신채널 상태를 확인할 수 없기 때문에 일반적으로 초기 셋팅 된 전송순서에 따라서 통신을 수행한다. 이 경우 프로세서 내부의 모든 프로세싱 노드에서 기존 수행 중인 통신이 종료된 후에야 스캐터 통신이 시작되는데, 이때 발생하는 전송 대기 시간을 줄임으로서 스캐터 통신 성능을 향상 시킬 수 있다. 본 기법에 의하여 스캐터 통신 성능이 향상되었고, BFM 시뮬레이션을 통하여 기존 알고리즘 대비 최대 78.93%의 성능 향상이 있음을 확인하였다.

We look at the rocket life stages of NaverZ's metaverse platform scaling and investigate the ignition and scale-up stage of its metaverse platform brand, Zepeto based on the Rocket Model (RM). The results are derived as follows: Firstly, NaverZ shows the event strategy by collaborating with K-pops, the piggybacking strategy by utilizing other SNSs, and the VIP strategy by investing in game and entertainment content genres in the 'attract' function. In the second 'match' function, based on the matching rule of Zepeto, the users can generate their own characters and "World" with Zepeto Studio. However, for strengthening the matching quality, NaverZ is investing in the artificial intelligence (AI) based companies consistently. In the 'connect' function, NaverZ's maximization of the positive interaction is possible by inducing feed activities in Zepeto & other SNSs and by uploading attractive content for viral effects in the ignition. For facilitating this, NaverZ expands the scale to other continents like Southeast Asia and Middle East with the localization strategy inclusive investment. Lastly, in the 'transact' function, based on three monetization experiments like Coin & ZEM, user generated content (UGC) fee, and advertising revenue in the ignition, NaverZ starts to invest in NFT platforms and abroad blockchain companies.

This paper proposes an improved stator flux estimator through ensuring conventional PLPF to act as a pure integrator for sensorless control of induction motors. Conventional PLPF uses the estimated synchronous speed as a cut-off frequency and has the gain and phase compensators. The gain and phase compensators are determined on the assumption that the estimated synchronous angular speed is coincident with the real speed. Therefore, if the synchronous angular speed is not same as the real speed, the gain and phase compensation will not be appropriate. To overcome the problem of conventional PLPF, this paper analyzes the relationship between the synchronous speed error and the phase lag error of the stator flux. Based on the analysis, this paper proposes the synchronous speed error compensation scheme. To achieve a start-up without speed sensor, the current model is used as the stator flux estimator at the standstill. When the motor starts up, the current model should be switched into the voltage model. So a stable transition between the voltage model and the current model is required. This paper proposes the simple transition method which determines the initial values of the voltage model and the current model at the transition moment. The validity of the proposed schemes is proved through the simulation results and the experimental results.

본 연구는 한국 여성의 골다공증 검진부위에 따른 검진결과와 유병률의 차이를 분석함으로써, 연령 증가에 따른 유병부위와 양상 변화를 파악하고자 하였다. 국민건강영양조사 3개년(2008-2010)의 대규모 자료를 활용하여, 전국을 대표하는 50-89세의 여성 4,449명을 연구대상으로 하였다. 연령집단별로 유병부위에 차이를 발견할 수 있었는데, 50대부터 70대까지는 요추 골다공증의 비중이 상대적으로 높은 반면, 80대에는 대퇴(경부 혹은 전체) 골다공증의 비중이 더 높았다. 단일부위 골다공증의 경우, 연령 증가에 따라 요추는 감소하지만 대퇴 경부는 증가했다. 복수부위 골다공증의 비중은 연령 증가와 함께 증가하며, 유병양상은 요추가 대퇴보다 선행하는 것이 일반적으로 판단된다. 따라서 50-70대 여성을 대상으로 대퇴만을 검진하는 경우, 골다공증 환자를 정상 판정하는 음성오류를 범할 가능성이 높다.

In this paper, we present an experimental investigation of the frequency characteristics and a visual inspection of an oxidizer pump with a modified rear-floating ring seal for a 7-tonf turbopump. An oxidizer pump typically operates at high rotational speeds and under cryogenic conditions. Despite its low hydraulic efficiency, the floating ring seal is frequently employed as a leakage control solution for turbomachinery because it effectively reduces abrasion by friction. When the oxidizer pump starts up, the floating ring moves excursively but locks up stably against the pump casing when the contact pressure increases. The compressive force on the floating ring depends on the hydrodynamic forces induced by the flow through the floating ring. This force is controlled by the nose position of the floating ring. Based on a validation test for a 7-tonf turbopump with two types of floating rings, we concluded that the floating ring with a small diameter nose can move easily with a low contact pressure in the cooling path. This leads to instability of the pressure fluctuation around the floating ring. In contrast, a floating ring with a large diameter nose has a high contact pressure and attaches strongly to the casing, which causes wear and frictional oxidation between the contact surfaces of the impeller and the floating ring.
