In this paper, we propose the development of an integrated intelligent parking control system using a 360° camera that has overcome the shortcomings of the existing parking control system. The system proposed in this paper consists of six items as follows. First, license plate recognition software when entering the vehicle, second, real-time parking space identification software using 360° image, third, real-time precision parking guidance software based on deep learning vehicle motion recognition, fourth, multi-license-plate recognition software using 360° image, fifth, real-time parking position identification software using 360° image, sixth, database server etc. Performance evaluation results were high in both recognition rate and time spent, and efficiency was confirmed.

N/A designed to evaluate the pattern of histocompatibility antigens(HLA) and its association with poor prognostic factors in patients with IgAN. Methods : Study population comprised the 69 patients with IgAN which was diagnosed by clinical and pathological findings, and control groups were 202 healthy Korean people. We evaluated the HLA class I serologic typing by standard microlymphocytotoxic technique and the HLA class II genotypes by the two-step polymerase chain reaction. Results : 1. HLA-A was not associated with IgAN. 2. The phenotype frequency of HLA-B55 was 6.1% in patient group and 1.7% in normal control group. HLA- B55 was associated with IRAN(relative risk 3.47, P<0.05). 3. HLA-DQB1*04 was also associated with IgAN (relative risk 3.57, P<0.05). 4. There was no significant difference in the distribution of HLA in IgAN patients according to histologic grading, blood pressure, renal function and proteinuria. Conclusions : Frequencies of HLA-B55, HLA-DQB1*04 are higher in Korean patients with IgAN compared to general population. But we could not observe the significant relationships between HLA type and poor prognostic factors. Further study using larger population with IgAN may be necessary to identify the association of HLA locus with poor prognostic factors and progress decline in renal function in patients with IgAN.

제휴할인카드 프로그램이 빠르게 확산되고 있는 외식업계의 일반적인 추세와 달리 베이커리업계는 고객보상제도 위주의 고객프로그램을 운영하고 있다. 경쟁이 치열해지고 시장이 성숙기에 접어들면서 베이커리 업계는 제휴카드와 같은 새로운 프로그램의 확대여부를 결정해야 하는 시점이다. 본 연구에서는 다양한 프로그램이 시행되고 있는 패밀리레스토랑의 사례분석을 통하여 향후 베이커리 업계가 나아갈 방향에 대한 시사점을 발견하고, 이러한 방향이 소비자와 기업의 관점에서 모두 합리적인 결정인지에 대한 이론적 고찰을 하였다. 또한 제휴카드별 효율성에 관련한 실증데이터분석을 통하여 제휴카드 선정과 평가기준 개발의 필요성을 밝혔다. Customer reward (loyalty) program has been implemented in food service industry for decades. However it is also observed that discount cards allianced with consumer banks, credit cards and mobile telecommunication companies are rapidly spreading. The alliance card discount program seems to be invented by the convergence of the conventional price discount promotions and the concept of marketing alliance with different industries. In spite of these trends, bakery industry has less utilized alliance discount cards than family restaurants. However the increasing competition drives bakery brands to consider the expansion of alliance card for future marketing strategy against competition. To identify the alternatives for future growth, was reviewed the case of family restaurants. And new variables and criteria for program evaluation were developed through the review of studies of related subjects and industry opinion because so far not enough studies conducted for the comparison between point reward card and alliance discount cards. Suggested four alternatives from the study were the expansion of alliance discount card, the increase of point reward ratio, the integration of point programs of other brands or industries, and the introduction of all time discount to loyalty program members. Those ideas were evaluated by the new measures mentioned above. Additionally how to improve executional excellence in alliance discount card operation was discussed in terms of profitability and sales impact. In this study, by the cost efficiency analysis of each program, it is found what the consideration variables should be in the selection of alliance partners and in the cost-share negotiation with them. The understanding of motivation factors and consideration variables is supposed to be a substantial assistance to develop future marketing strategy in food service industry.

Objective: The purpose of this study was conducted to investigate indoor air quality in submarine. Method: For the indoor air quality testing in submarine, we investigated nine submarines. Measurement for 1st period was from Jun, 2012 to Jul, 2012 and 2nd period was from Apr, 2013 to May, 2013 and 3rd period was from Jun, 2013 to Jul, 2013 and 4th period was Oct, 2013. Six type 209 submarines and three type 214 submarines were involved. Results: The mean indoor air carbon dioxide(CO2), carbon monoxide(CO), and nitrogen dioxide(NO2) levels of 1st period in submarine were 1932.25 ppm, 21.57 ppm, 0.053 ppm for each other. The result was found to be exceed that recommended in the air quality standards by Ministry of Environment Republic of Korea(KMOE). The mean indoor air CO2, NO2 levels of 2nd and 3rd period were found to be exceed that recommended standards by KMOE. There was CO2 which indoor air quality level exceeds that standards by KMOE for 4th period. Conclusion: It seems that current administration for indoor air quality in submarine is not poor. Persistent concern will be needed.

As the beauty service industry becomes segmented and specialized into the hair, makeup, skin care, and nail art fields, it is poised to become a main area in the service industry; however, despite its consistent increase in size, there is a need for reasonable marketing strategies with the ensuring of talented persons and a reduction of service fees. Consequently, this study aimed to conduct comparative research into the current use of beauty services aimed at the spouses and children of customers who use beauty services. First, as a result of carrying out a cross analysis of a comparison in the current use of research subjects, their spouses, and children regarding the most used treatment and the most desired to use treatment among the three groups, it was discovered that they were in the order of a perm and coloring. For spouses, the order was coloring and cut, while for children it was cut. Concerning the average treatment cost per treatment of the three groups, the research subjects were found to spend 40,000 won or over, their spouse over 10,000 won to less than 20,000 won, and their children less than 10,000 won. In case of the average cost per treatment of a general perm, the research subjects were discovered to spend over 60,000 won to less than 80,000 won, their spouses over 20,000 won to less than 40,000 won, and their children less than 20,000 won. Regarding the payer for the treatment cost of the three groups, the payer for the research subjects was discovered to be their parents and the research subjects, for the spouses it was themselves, and for their children it was themselves. From this, it was shown that the use pattern of beauty services among the research subjects, their spouses, and their children was different. In reviewing the above results, in the beauty service industry, it is necessary to identify the characteristics of family customers accurately; thus, a suitable service may be offered to their satisfaction. In addition, if beauty service managers utilize technical service and management marketing suited to family customers, this will be a foundation for an increase in sales from long-term customers.

본 논문에서는 제로포싱 빔형성 (ZFBF)을 이용한 Multiuser MIMO-OFDM 시스템에서 각 사용자의 주어진 요구정보량을 만족시키면서 총송신전력을 최소화하기 위한 부반송파 할당방법을 제안한다. 최적 방법의 복잡도는 부반송파의 수에 지수적으로 비례하여 증가하기 때문에 복잡도를 줄이기 위한 부최적 방법을 제안한다. 부최적 방법에서는 사용자 그룹의 채널간 직교도가 클수록 유효채널이득이 증가하는 특성을 이용하여 채널간 직교도가 큰 사용자 그룹을 할당함으로써 송신전력을 최소화한다. 모의실험 결과에서 제안한 부최적 방법이 복잡도를 현저히 감소시키면서 총 송신전력의 측면에서는 최적화된 방법과 유사한 성능을 가진다는 것을 보인다. In this paper, a low complexity subcarrier allocation scheme is proposed for multiuser MIMO-OFDM systems with zero-forcing beamformer (ZFBF) so that the total transmit power can be minimized satisfying given target data rate. Since the optimal method requires very high computational complexity, we propose a low complextiy suboptimal method. Using the fact that the effective channel gain is proportional to the orthogonallity of channels of multiplexed users, a user set with the highest orthogonality of channel among users is assigned to each subcarrier in order to minimize required transmit power. The numerical results show that the proposed suboptimal method can reduce computational complexity with little performance loss.
