  • Throughout history, there are three clues of dualistic structures for the development of Hong Kong's nativism. First, inward attribution and outward lookingare two paths to the formation of Hong Kong's nativism. In the dualistic framework of "self-others", nativism is formed. The formation path of "outward looking"can be seen everywhere in the construction history of Hong Kong's nativism. It is under the reflection of "two mirrors" with Britain and Chinese mainland that Hong Kong people acquire the concept of "Hong Kong's nativism". Second, there are two aspects of Hong Kong's nativism: economic and cultural aspect and political aspect. With the gradual development of Hong Kong's history, these two aspects come into being and are closely bound up, thus constituting Hong Kong's nativism today. The third clue is the most critical one. The subjectivity of colonization and decolonization are two different forms of Hong Kong people's subjectivity. These three clues run through the whole process of the construction of Hong Kong nativism, and are carried out in three stages of development: "Origin (1960s-1970s): Preliminary Construction of Hong Kong's Nativism", "Development of Hong Kong's Nativism (1980s-1997): Awakening of Political Aspect" and "Formation and Alienation of Hong Kong's Nativism (1997-present): Deformed "decolonization". Along the evolution of Hong Kong's nativism, with the disintegration of colonialism, Hong Kong people have gradually transited from the subjectivity of colonization to the subjectivity of decolonization, but the process of "decolonization" has not been completed up to now.When nativism loses its native complex from the perspective of "inherent in China", and further develops into the "separatism" of anti-constitutional system and anti-national continuity and unity, it will challenge the stability of the relationship between the central government and the Special Administrative Region under the "one country, two systems". At the same time, it will have a greater impact on the political structure and the rule of law system of Hong Kong, and trigger a series of public law problems that need to be solved urgently. In this regard, on the one hand, we should re-clarify the relationship between the central government and the region under the "one country, two systems" in light of the new situation of democratic political development in Hong Kong, and improve Hong Kong's governance mechanism on the basis of the constitution and the basic law; on the other hand, we should actively learn from the German defensive democracy system to systematically interpret, integrate and apply Hong Kong's existing legal resources so as to effectively curb the development of local separatist forces.

  • Purpose In this study, the monthly population distribution was calculated for statistical verification of 10 tests (CA19-9, CA15-3, testosterone, PTH, calcitonin, AFP, CEA, CA72-4, PSA, estradiol) with changed reagents, and the trend of change By comparing and analyzing the results, we want to verify the accuracy of the results and improve the reliability of the test. Materials and Methods From June 2021 to February 2023, for the 10 items in which the reagent was changed, the monthly percentage and standard deviation index before and after the reagent change were compared, respectively. At this time, the reference value was arbitrarily set for the comparison group in consideration of the reference value of the test item, and the groups were subdivided and compared, and the standard deviation index allowed range was -2.0 or more and 2.0 or less. Results For CA19-9, CA15-3, AFP, CEA, and calcitonin 5 test items, the change in monthly ratio in all test sections before and after the reagent change was kept constant. On the other hand, for CA72-4, PSA, testosterone, PTH, and estradiol items, the standard deviation index exceeded the acceptable standard after changing the reagent. CA72-4 test items showed an increasing trend in standard deviation index in the test section exceeding the reference value. In the case of the PSA test item, the maintenance ratio of 0.04 ng/mL was significantly decreased after changing the reagent. The testosterone test item had a standard deviation index of -2.5 in the test section exceeding 10.1 ng/mL after changing the reagent, and the standard deviation index of the PTH test item was out of the acceptable range in all test sections. It was confirmed that the estradiol test item showed an overall increase in the result value. Conclusion Through this study, the continuity and accuracy of the test results could be verified. It is considered that the stability of the test can be secured by analyzing the factors affecting the test result and solving the cause for the test item whose standard deviation index is out of the acceptable standard.

  • Restoration, prediction and noise analysis of geomagnetic data measured in the Korean Peninsula were performed. Restoration methods based on an optimized principal component analysis (PCA) and the geostatistical kriging approach were proposed, and its effectiveness was also interpreted. The PCA-based method seemed to be effective to restore the periodical signals and the geostatistical approach was stable to fill the gaps of measurements. To analyze the noise level for each observatory, the geomagnetic time-series was plotted by scattergram which reflects the spatial variation, using data observed during same period. The scattergram showed that the observation made at Cheongyang seemed to have better quality in spatial continuity and stability, and the restoration result was also better than that of Icheon site. For the restoration, both of the methods, geostatistical and optimizaed PCA, showed stable result when the missing of observation was within 20 points. However, in case of more missing observations than 20 points and prediction problem, the optimized PCA seemed to be closer to the real observation considering the frequency-domain characteristics. The prediction using the optimized PCA seems to be plausible for one day of period for interpretation.

  • Identify the effects of ISO quality management system on the durability of the enterprise by applying it to early startups and small - and medium-sized enterprises. In particular, the quality management system of a technology start-up small and medium sized companies is important in applying the management system to the financial, management and quality control services rather than to research and development. The quality management system is applied to the medical equipment manufacturers, mobile phone brokers, foreign Chinese companies, and components manufacturers for diesel engines.Try it. Check the case where the quality management system has been applied to the company concerned and the nonconformities have been improved. In addition, the success of the project was determined by applying the quality control system to maintain the stability and perpetuation of the company through the case of the failed selection. The company explains that recently, it must appoint internal auditors to carry out continuous improvement activities and that those who want the development and continuity of the company must reflect the quality management system.

  • The delivery of multimedia that efficiently adapts its bit-rate to changing network characteristics and conditions is one of the important challenging tasks in the design of today's real-time multimedia streaming systems such as IPTV, Mobile IPTV and so on. In these work, the primary focus is on network congestion, to improve network stability and inter-protocol fairness. However, these existing works have problems which do not support QoE (Quality of Experience), because they did not consider essential characteristics of contents playback such as the media continuity. In this paper, we propose a novel rate control scheme for improving the QoE of multimedia streaming service in the Internet congestion, called NCAR (Network and Client-Aware Rate control), which is based on network-aware congestion control and client-aware flow control scheme. Network-aware congestion control of the NCAR offers an improving reliability and fairness of multimedia streaming, and reduces the rate oscillation as well as keeping high link utilization. Client-aware flow control of NCAR offers a removing the media discontinuity and a suitable receiver buffer allocation, and provides a good combination of low playback delay. Simulation results demonstrate the effectiveness of our proposed schemes.

  • With the virtual asset market's rapid growth, government regulations on listing and trading procedures are expected. However, specific measures are currently lacking. To ensure stable inclusion in the institutional framework, precise regulations are needed for market development and investor protection. This study compares self-regulatory guidelines of the top domestic virtual asset exchanges with Korea Exchange's Preliminary Listing Examination Standards (2022) to enhance timeliness and relevance. It defines IEO, IPO, and ICO concepts and addresses conflicts of interest in IEO. Analyzing delisted virtual assets, it categorizes issues and classifies listing examination guidelines into formal and qualitative requirements. The study examines self-regulatory guidelines based on continuity, transparency, stability, corporate characteristics, and investor protection criteria, along with five special requirements for virtual assets. Improvement measures include regular disclosures of governance structure, circulation volume, and the establishment of independent audit institutions. This research further analyzes delisting cases, classifies issues, and proposes solutions. Considering stock market similarities, it offers measures based on the institutional framework.

  • Loss of continuity of the mandible destroys the balance and symmetry of mandibular function, leading to altered mandibular movements and deviation of the residual fragment towards the resected side. Apart from deviation, other dysfunctions include difficulty in swallowing, speech, mandibular movements, mastication, and respiration are accompanied. In general, surgical reconstruction is considered first then proceeds to the prosthetic restorations. However, patients with systemic disease such as BRONJ (Bisphosphonate related osteonecrosis of the Jaw), surgical reconstruction may be limited. Thus, the prosthetic restoration remains as the only resort. Numerous prosthetic methods are employed to minimize deviation and to improve masticatory efficiency, function and esthetics. If a removable partial denture is the selected treatment modality, maximum stability of the partial denture base may be accomplished with a functional impression procedure by means of eliminating lateral and horizontal forces caused by the functional movements of the lips, cheeks and tongue. Also, Twin occlusion is used to obtain a favorable occlusal relationship and check support for esthetics. The purpose of this case report is to demonstrate how neutral zone impression technique and twin occlusion scheme were applied to restore a hemi-mandiblectomy patient with BRONJ syndrome to achieve satisfactory results in functional and esthetic aspects.

  • This study examines the changing paradigm of family welfare policy and tries to find an appropriate model for the delivery system of family welfare service. First, the study reviews the contexts of family policy in new paradigm, and traces the changing process of family welfare-related administration from the ministry of human and health to the ministry of family and gender equality. Second, the study examines the principles of the delivery system for family welfare service to pursue the advancement of family policy. In conclusion, it proposes an alternative model for the successful settlement into community of family welfare delivery system, and a desirable position and role of family support center. The principles of the delivery system of family welfare service is fundamentally to make family policy come realistic, such as strengthening family stability through the harmonic reconciliation of work and family, preventing any forms of families from social safety net, and securing happy lives. Comprehensiveness, continuity, effectiveness, and accessibility of the system are also needed. In particular, family support center, recently very controversial, could be better as a representative council of networking various kinds of community organizations in the fields of family welfare enhancement, rather than organization of direct service provision, such as family counselling, education and therapy. Finally, an alternative model of delivery system for family welfare service is presented.

  • Arthroscopic anterior cruciate ligament(ACL) reconstruction using four-strand hamstring tendon with looping around transfixing screw in femoral tunnel requires osteointegration between the grafted tendon and bone for stability of the knee. Authors have experienced a histologic finding of osteointegration between the grafted autogenous hamstring tendon and bone in femoral tunnel after arthroscopic ACL reconstruction. A patient received arthroscopic ACL reconstruction with autogenous four strand hamstring tendon for the ACL injury. Traumatic re-rupture of mid-substance of ACL graft was developed at thirteenth week after operation. During the procedures of arthroscopic revision at fifteenth week after initial ACL reconstruction, biopsy was performed at the site of interface between grafted tendon and bone in femoral tunnel. Integration between the grafted tendon and bone was evident by demonstrating the continuity of collagen fiber between bond and tendon. This histologic finding and the low incidence of early graft failure suggest that free tendon autograft attached to bone by looping around a transfixing screw in femoral tunnel undergoes adequate osteointegration between 12 and 15 weeks after surgery and authors thought that insertion of bone chip into the femoral tunnel would accelerate osteointegration procedure.

  • Data composite methods have been typically applied to satellite-based vegetation index(VI) data to continuously acquire vegetation greenness over the land surface. Data composites are useful for construction of long-term archives of vegetation indices by minimizing missing data or contamination from noise. In addition, if multi-sensor vegetation indices that are acquired during the same composite periods are used interchangeably, data stability and continuity may be significantly enhanced. This study evaluated the influences of sensor geometry on MODIS vegetation indices and investigated data compatibility of two difference vegetation indices, the Normalized Difference Vegetation Index(NDVI) and the Enhanced Vegetation Index(EVI), for potential improvement of long-term data construction. Relationships between NDVI and EVI turned out statistically significant with variations among vegetation covers. Due to their curvilinear relationships, NDVI became saturated and leveled off as EVI reached high ranges. Correlation coefficients between Terra- and Aqua-based vegetation indices ranged from 0.747 to 0.963 for EVI, and from 0.641 to 0.880 for NDVI, showing better compatibility for EVI compared to NDVI. In-depth analyses of VI outliers that deviated from regression equations constructed from the two different sensors remain as a future study to improve their compatibility.
