In many cases, human's visual recognition depends on contextual information. We need to use effective feature information for performing vigorous place recognition to illumination, noise, etc. In the existing cases that use edge and color, etc., visual recognition doesn't cope effectively with real environment. To solve this problem, using natural marker, we improve the efficiency of place recognition.

Tuberculosis is a chronic disease caused by Mycobacterium tuberculosis, which usually affects the lung but may cause lesions in any organ or tissue of the human body. Mediastinal lymph node involvement is common feature of intrathoracic tuberculosis in children. Sometimes the lymph node may be enlarged and it causes compressive symptoms. Recently we experienced two cases of tuberculous abscess at middle mediastinum. The abscess seemed to be originated from the mediastinal lymphadenitis, and caused the symptoms. Operation was performed by median sternotomy and by posterolateral thoracotomy incision respectively for the purpose of relieving symptoms and diagnosing the mediastinal mass. The symptoms were relieved completely and postoperative course was uneventful.

Background: Cold knife conization is a surgical procedure that allows both diagnosis and treatment of cervical lesions at the same time. It is mainly performed for indications of high-grade cervical intraepithelial neoplasia (CIN). In this study, we aimed to investigate the clinical outcome of cases without CIN in cold knife conization specimen, following a high-grade lesion (CIN2/3) in cervical biopsy. Materials and Methods: We performed a retrospective cohort study at a tertiary referral hospital between January $1^{st}$ 2008 and August $1^{st}$ 2012. Cases that underwent cold knife conization for CIN2/3 within the study period were included. Cone-negative (Group 1) and cone-positive (Group 2) cases were analyzed for various clinical parameters, and were compared in the 1-year post-conization period for histological recurrence and human papillomavirus (HPV) DNA status. Results: A total of 173 women underwent cold knife conization for CIN2/3 within the study period. Twenty-two cases (12.7%) were included in Group 1 and 151 cases (87.3%) in Group 2. There were no significant differences between the two groups in terms of age, gravidity, parity, menopausal status and HPV-DNA status (pre-conization and 1 year post-conization) (p>0.05). Recurrence rates were also similar between the groups (9.1% vs 9.9%, p>0.05). Conclusions: Clinical outcomes were similar in terms of histological recurrence and HPV persistence after 1 year of follow-up between cone-negative and cone-positive cases. Clinical follow-up of cone-negative cases should therefore be performed similar to cone-positive cases.

In this paper, a kidnapping detection scheme in which human pose estimation is used to classify accurately between kidnapping cases and normal ones is proposed. To estimate human poses from input video, human's 10 joint information is extracted by OpenPose library. In addition to the features which are used in the previous study to represent the size change rates and the regularities of human activities, the human pose estimation features which are computed from the location of detected human's joints are used as the features to distinguish kidnapping situations from the normal accompanying ones. A frame-based kidnapping detection scheme is generated according to the selection of J48 decision tree model from the comparison of several representative classification models. When a video has more frames of kidnapping situation than the threshold ratio after two people meet in the video, the proposed scheme detects and notifies the occurrence of kidnapping event. To check the feasibility of the proposed scheme, the detection accuracy of our newly proposed scheme is compared with that of the previous scheme. According to the experiment results, the proposed scheme could detect kidnapping situations more 4.73% correctly than the previous scheme.

It has been reported that long-term exercise on a treadmill (running machine) may cause injury to the joints in a human's lower extremities. Previous works related to analysis of human walking motion are, however, mostly based on clinical statistics and experimental methodology. This paper proposes an analytical methodology. Specifically, this work deals with a comparison of normal walking on the ground and walking on a treadmill in regard to the external and internal impulses exerted on the joints of a human's lower extremities. First, a modeling procedure of impulses, impulse geometry, and impulse measure for the human lower extremity model will be briefly introduced and a new impulse measure for analysis of internal impulse is developed. Based on these analytical tools, we analyze the external and internal impulses through a planar 7-linked human lower extremity model. It is shown through simulation that the human walking on a treadmill exhibits greater internal impulses on the knee and ankle joints of the supporting leg when compared to that on the ground. In order to corroborate the effectiveness of the proposed methodology, a force platform was developed to measure the external impulses exerted on the ground for the cases of the normal walking and walking on the treadmill. It is shown that the experimental results correspond well to the simulation results.

As human factors are the most important cause of construction accidents, it is important to reduce human error in construction work to reduce accidents. However, the error forcing context in organizational situations acts as a factor behind human error. Therefore, fatal construction accidents were analyzed using the m-SHEL model, which can identify the factors behind human errors. Through such analysis, it was found that there are differences in the detailed factors behind human errors according to the type of fatal accidents in construction, This study is meaningful in that it confirmed through accident cases that it is important to understand and respond to organizational situations in order to reduce human error in construction work.

Helicopter pilots are required to perform many visual workloads in topographical avoidance, flight path modification and navigation, because helicopters operate at very low altitudes. The helicopter-specific instability also require the pilot to have precise perception and control. This has caused frequent human error in helicopter accidents. In Korea, two to three cases have occurred annually on average over the past 10 years, and this trend has not decreased. The purpose of this study was to identify human error risks in advance to prevent helicopter accidents and to help develop measures for missions and mission phases with high risk of human error. Through the study, the tasks and mission phases where accidents occur frequently were classified and the risk of human error was calculated for each mission phases. To this end, the task of frequent accidents during helicopter missions was first identified, detailed steps were classified, and the number of accidents was analyzed. Next, the AHP survey program was developed to measure the pilot's risk of human error and the survey was conducted on the pilots. Finally, the risk of human error by helicopter mission and by mission phases calculated and compared with the actual number of accidents.

Herpes simplex virus type 1 and 2(HSV-1, HSV-2) are the ubiquitous human pathogens responsible for a variety of afflictions. HSV-2 is one of the viruses that were suspected of promoting carcinogenesis in the uterine cervix. Certainly, there is a need for the more sensitive and accurate laboratory techniques for HSV detection. We examined total 80 cases of smears including 17 Tzanck smears of skin and 63 cases of Papanicolaou smears from total 77 patients with clinical impression of herpetic infections, from September, 1985 through August, 1989. Immunohistochemical typings for HSV-1 and HSV-2 were performed together with routine cytologic findings and compared. The results are as follows : 1) Patients were 9 males and 33 females, and age distribution was between 5 and 71 years. 2) Subjective symptoms such as ulceration, vesicle, vaginal discharge, pruritus, and pain were complained in 36 patients and 38 cases were genital herpes. Recurrence was noted in 11 cases. 3) Positive results were obtained in 42 among 80 cases. 4) Both routine cytology and immunohistochemical staining were positive in 13 cases and in 24 cases only immunohistochemical staining were positive. 5 cases were positive only in routine cytologic smears. 5) The cases that immunocytochemical stain had been performed were 37 cases, which were all positive in type 2. Among the above 37 cases, type 1 also were positive in 5 cases. The results show that the immunoperoxidase technique is one of the rapid and reliable method to confirm the herpetic infection when suspected and that it is particularly useful when the Papanicolaou smear findings are equivocal.
