Objectives: This systematic review aimed to put the case reports of lung cancer on Korean medicine (KM) together and adopt the results in clinical practice. Methods: Researches were searched using the PubMed, EMBASE, OASIS, KoreanTK, KISTI, RISS, KISS, and NDSL. The search term were 'lung cancer' and KM. There was no restriction in year. Results: 1. Among the 48 studies, 68 patients were reported in total. The types of lung cancer were non-small-cell lung cancer (n=41) and small-cell lung cancer (n=6). 2. The number of patients who received KM therapy alone was 40. On the other hand, 25 patients were treated with KM and chemotherapy simultaneously. All case reports used herbal medicine except 2 studies. Other types of treatment were acupuncture, moxibustion, pharmacopuncture, cupping, meditation, etc. 3. Several efficacy evaluation variables were used such as tumor size, changes of symptoms, duration of survival, the quality of life, and so on. The safety was evaluated by checking adverse effects using blood test. 4. Regarding the tumor response, partial response was reported in 12 cases, stable disease was in 22 cases, 50% of the total cases, which is a high level of tumor response. Furthermore, all 11 cases with the evaluation on the length of survival showed prolonged survival than the expectancy of corresponding stage, with the stable quality of life. Conclusion: We have found that the applicability of KM for treatment of lung cancer through this review. Evidence based medicine can be realized by checking cases and applying them in clinical practice.

Inventory inspection is an important task to eliminate the inconsistency between real assets and inventory management systems, and it is performed periodically at the site. In the case of a large-sized property, it is mainly managed in an outdoor workshop or a warehouse. However, due to the large area of the outdoor area, it is relatively difficult to identify the quantity and location of the property and is also vulnerable to theft. To solve this problem, we proposed a method and system for performing a warehouse inventory inspection using an unmanned aerial vehicle (UAV) and Bluetooth low energy (BLE) beacons. The proposed method has the following advantages. First of all, if we carry out inventory inspection by utilizing UAV, we can minimize user's effort compared to existing methods. The method of recognizing the asset by attaching the BLE beacon is more costly than using the existing RFID technology, but it is advantageous because the recognition distance is increased and the battery life of the tag is drastically increased. We also designed a BLE beacon reader for the system and implemented a prototype to show the feasibility of the proposed system. The prototype is based on Genuino 101, which is a kind of arduino, and adds HM-10 and Neo-6m modules to provide Bluetooth and GPS functions. The BLE beacon reader was tested in outdoor, and attached in drone. We also developed an inventory checking system based on the web to display results of inventory checking. The proposed approach enables the users to automate the operation of inventory checking on an outdoor warehouse.

In case of an embedded system having an LCD panel with touch-screen capability, various figures such as rectangles, pentagons, circles, and arrows are frequently used for the delivery of user-input commands. In such a case, it is necessary to have an algorithm that can recognize whether a touched location is within a figure on which a specific user-input command is assigned. Such algorithms, however, impose a considerable amount of overhead for embedded systems with restricted amount of computing resources. This paper first describes a method for initializing and driving a touch-screen LCD and a coordinate-calibration method that converts touch-screen coordinates into LCD panel coordinates. Then it introduces methods that can be used for recognizing touched areas of rectangles, many-sided figures like pentagons, and circles; they are a range checking method for rectangles, a crossing number checking method for many-sided figures, a distance measurement method for circles, and a color comparison method that can be applied to all figures. In order to evaluate the performance of these methods, we implement two-dimensional graphics functions for drawing figures like triangles, rectangles, circles, and images. Then, we draw such figures and measures times spent for the touched-area recognition of these figures. Measurements show that the range checking is the most suitable method for rectangles, the distance measurement for circles, and the color comparison for many-sided figures and images.

To investigate the effect of presurfacing, both 25mm rough and pre surfaced oak boards (Quercus grosseserrata BI.) were dried in the same dry kiln condition. Drying curves, drying strains and drying defects of rough and presurfaced boards were compared. The results obatained are as follows. 1. Average drying rate of rough and presurfaced boards from green to 10% M.C. was 0.276%/hr. and 0.284%/hr., respectively. 2. At the early stage of drying, in case of rough boards, maximum tensile strain of outer slices was $-24.2{\times}10^{-4}$mm/mm and maximum compressive strain of innermost slices was $13.0{\times}10^{-4}$mm/mm, and in case of pre surfaced boards, maximum tensile strain of outer slices was $-14.5{\times}10^{-4}$mm/mm and maximum compressive strain of innermost slices was $28.1{\times}10^{-4}$mm/mm. And in both cases, stress reversal occurred at about 40% M.C.. 3. Maximum surface checking appeared at about 40% M.C.. Of the 10 rough boards. 6 hoards contained surface checks, but presurfaced boards did not contained surface checks after drying. And the results of end checking were similar to those of surface checking. But, honeycomb was not found in both cases. 4. Board shrinkage. warp and casehardening of presurfaced boards were similar to those of rough boards. But, collapse of prsurfaced boards was less than that of rough boards.

A lot of computer users use external memory device. But, same time file efflux incidents are also increasing. There are two ways people use for efflux file. One is moving it after checking file which is running on computer and the other is checking file name only. Checking from running file case, we can identify vestige with running information of applied program but, the case of moving as external device without running file there is no evidence running applied program. So there are a lot of difficulty with forensic investigation. In this paper we suggest the way to help forensic investigation which is method of getting external memory device information of volume and time through its awareness method and connection information and moving to external device without running file after compare the external memory device volume information through link file analysis and getting information of link file formation & access time from link file.

There is the difference of criteria to apply guidelines among the project participants and to depend on the purpose of utilizing BIM models, although modeling criteria are basically provided through BIM guidelines. Therefore, it is quite important to check compliance with guidelines to raise quality of the BIM model. But Quality Checking (QC) items and method for BIM model modeled in accordance with guidelines is not provided. This study suggested QC items and Rule Specifications(RS) for automatic QC. First of all, QC items were derived by analyzing domestic BIM guidelines and a process for structuring natural language is conducted by utilizing flowchart and pseudocode. So, by combining them, RS was suggested. Finally, RS-based case study was conducted by implementing automatic QC process with solibri model checker$^{TM}$. This study will contribute to the improvement of design quality and completeness of BIM model including huge data of 3 dimension. Furthermore, it is necessary to develop BIM guidelines according to the use case and to provide detailed process and standard for QC of BIM model.

In the development of complex software system, it is important to use hierarchical use case model due to the complex scope of development procedure. The use case model is core factor of the OMG (Object Management Group)'s UML (Unified Modeling Language) diagrams. In this paper, we propose a novel method to check syntactic consistency automatically in use case models at the different level of abstraction. This method is a rule-based approach which utilizes actor tree, use case tree and use case description. The proposed method is simulated on ITS (Intelligent Transportation System) architecture for the verification.

Objectives: We report two cases that have an effective result with Korean traditional medical treatment to two patients who have uterine fibroids, using transabdominal ultrasonography for checking the size of uterine fibroids. Methods: A 44-year-old patient and a 43-year-old patient were treated with an herbal medicine, acupuncture and cupping therapy. We followed up the symptoms and the size of uterine fibroids. Results: The 44-year-old patient was asymptomatic, her size of the uterine fibroid was reduced for 6 months. Also, the 43-year-old patient experienced that the symptoms such as urinary frequency, ovulation pain, heavy bleeding were improved and the size of the uterine fibroid was reduced. Conclusions: This results suggest that Korean traditional medical treatment if effective for both asymptomatic and symptomatic uterine fibroids and ultrasonography is useful for checking the effect of Korean traditional medical treatment. Further case series and studies are warranted.

We propose a low cost attendance checking system using NFC (Near Field Communication) and show a case study of an actual operation of the system in a higher education institute. The system offers a direct attendance check service when a student touches NFC tag on a classroom desk with his/her own smartphone. Our service was first developed and operated in 2012, and then additional functions like massive real time processing were reinforced. In the fall semester, 58 courses use the service and 96% of the class attendance was checked with mobile devices. The only hardware requirement of the system was NFC tag on the classroom desk, which reduced hardware cost dramatically. However, it also minimized attendance checking time into 1 minute regardless of enrolled student number.
