Detection of Precise Crop Locations under Vinyl Mulch using Non-integral Moving Average Applied to Thermal Distribution

조용진,윤예지,이규승,이동훈 한국농업기계학회 2017 바이오시스템공학 Vol.42 No.2

Purpose: Damage to pulse crops by wild birds is a serious problem. The damage is to such an extent that the rate of damage during the period between seeding and cotyledon stages reaches 54.6% on an average. In this study, a crop-position detection method was developed wherein infrared (IR) sensors were used to determine the cotyledon position under a vinyl mulch. Methods: IR sensors that helped measure the temperature were used to locate the cotyledons below the vinyl mulch. A single IR sensor module was installed at three locations of the crops (peanut, red lettuce, and crown daisy) in the cotyledon stage. The representative thermal response of a 16 × 4 pixel area was detected using this sensor in the case where the distance from the target was 25 cm. A spatial image was applied to the two-dimensional temperature distribution using a non-integral moving-average method. The collected data were first processed by taking the moving average via interpolation to determine the frame where the variance was the lowest for a resolution unit of 1.02 cm. Results: The temperature distribution was plotted corresponding to a distance of 10 cm between the crops. A clear leaf pattern of the crop was visually confirmed. However, the temperature distribution after the normalization was unclear. The image conversion and frequency-conversion graphs were obtained based on the moving average by averaging the points corresponding to a frequency of 40 Hz for 8 pixels. The most optimized resolutions at locations 1, 2, and 3 were found on 3.4, 4.1, and 5.6 Pixels, respectively. Conclusions: In this study, to solve the problem of damage caused by birds to crops in the cotyledon stage after seeding, the vinyl mulch is punched after seeding. The crops in the cotyledon stage could be accurately located using the proposed method. By conducting the experiments using the single IR sensor and a sliding mechanical device with the help of a non-integral interpolation method, the crops in the cotyledon stage could be precisely located.

Estimation of Moisture Content in Comminuted Miscanthus based on the Intensity of Reflected Light

조용진,이동훈 한국농업기계학회 2015 바이오시스템공학 Vol.40 No.3

Purpose: The balance between miscanthus production and its cost effectiveness depends greatly on its moisture contentduring post processing. The objective of this research was to measure the moisture content using a non-destructive andnon-contact methodology for in situ applications. Methods: The moisture content of comminuted miscanthus was controlledusing a closed chamber, a humidifier, a precision weigher, and a real-time monitoring software developed in this research. ACMOS sensor equipped with 50× magnifier lens was used to capture magnified images of the conditioned materials withmoisture content level from 5 to 30%. The hypothesis is that when light is incident on the comminuted particles in aninclined manner, higher moisture content results in light being reflected with a higher intensity. Results: A linear regressionanalysis for an initiative hypothesis based on general histogram analysis yielded insufficient correlations with lowsignificance level (<0.31) for the determination coefficient. A significant relationship (94% confidence level) wasdetermined at level 108 in a reverse accumulative histogram proposed based on a revised hypothesis. A linear regressionmodel with the value at level 108 in the reverse accumulative histogram for a magnified image as the independent variableand the moisture content of comminuted miscanthus as the dependent variable was proposed as the estimation model. Thecalibrated linear regression model with a slope of 92.054 and an offset of 32.752 yielded 0.94 for the determinationcoefficient (RMSE = 0.2%). The validation test showed a significant relationship at the 74% confidence level with RMSE6.4% (n = 36). Conclusions: To compensate the inconsistent significance between calibration and validation, an estimationmodel robust against various systematic interferences is necessary. The economic efficiency of miscanthus, which is apromising energy resource, can be improved by the real-time measurement of its crucial material properties.

The purpose of this study is to investigate the Influence of Human Capital of Hotel Employees on Knowledge Management Activity and Innovation Behavior based on hypotheses based on research model through previous studies. Based on the theoretical background, two hypotheses were set up. The purpose of this study is to analyze the Influence of Human Capital of Hotel Employees on Knowledge Management Activity and Innovation Behavior. The survey was conducted from July 1, 2018 to July 30, 2018 using the convenience sampling method, which is a non-probabilistic sampling method. A total of 250 questionnaires were distributed, of which 207 were used for empirical analysis, except for the unsuccessful or inconsistent questionnaires (43 copies). As a result of using the statistical program of SPSS 21.0 and AMOSS 21, the hypotheses were verified and it was found that there was a causal relationship between human capital and knowledge management activities, knowledge management activities and innovation behaviors of Hotel Convention employees. Therefore, the hypotheses presented through the rationale of the previous research are adopted in this study. The academic implications of this study are as follows: Human capital (work ability, communication) of hotel employees showed that the knowledge management activities (knowledge creation, knowledge sharing).

Gradual Lengthening of the Ulna in Patients with Multiple Hereditary Exostoses with a Dislocated Radial Head

조용진,정성택 연세대학교의과대학 2014 Yonsei medical journal Vol.55 No.1

Purpose: Multiple hereditary exostoses of the forearm typically form in the distal ulna, causing disturbances in the growth of the ulna and functional disability. Multiple hereditary exostoses inhibit the growth of the ulna, leading to an acquisition of a varus deformity in the radius, which sometimes leads to dislocation of the radial head, the development of limitations in the pronation-supination of the forearm,and cosmetic problems. Materials and Methods: We retrospectively reviewed the cases of four patients who had deformities of the forearm with radial head dislocation associated with multiple hereditary exostoses, and evaluated the radiologic and clinical results of excision of the osteochondromas from the distal ulna and gradual ulnar lengthening with an Ilizarov external fixator. Results: Good clinical and radiological results were obtained after a mean follow-up of 25 months. At the most recent follow-up, radial bowing, ulnar shortening, carpal slip, and the pronation/supination arch of the forearm had improved. There was little change in terms of preoperative radial articular angle and the flexion/extension arch of the elbow by the most recent follow-up. Conclusion: Treatment of four forearms from four patients by excision of osteochondromas and gradual lengthening of the ulna with an Ilizarov external fixator spontaneously reduced dislocations of the radial heads without the need for any additional operative intervention. All patients were satisfied with the final results.

This study was performed to find out drying characteristics and develop drying model for the design of an efficient dryer or drying system of red peper. The basic model which describes drying phenomenon of red pepper was firstly established, and drying tests were conducted at 14-different drying conditions. In this test, the effects of drying air temperature and relative humidity on the rate of drying were undertaken. Finally, a new drying model based on these experimental results was developed to describe the drying characteristics of red pepper. The results from this study may be summarized as follows. 1. Drying constant of the basic model established from Lewis' experimental model and diffusion equation was theoretically deduced as a function of moisture content and inner-temperature of red pepper. 2. From the results of drying tests, drying air temperature was found to have the greatest effect on the rate of drying. However, the effect of temperature was small for the condition of high relative humidity, and for low temperature, the effect of relative humidity was found to be large even though the range of relative humidity was low. 3. Modified Henderson equation was found to be better than Chung equation as the EMC model for the estimation of the equilibrium moisture content of red Pepper. 4. Constant-rate drying period did not exist in the red pepper drying test. And falling-rate drying period was divided into three distinct phases. Drying rate was dependent on the moisture content, the inner-temperature of red pepper and the change of physical property due to drying. 5. Drying constant increased with decrease of free moisture content, but it decreased at the end of the drying period. Also, drying constant was dependent on the drying air temperature and relative humidity. 6. The new drying model developed in this study was found to be most suitable in describing the drying characteristics of red pepper. Therefore, it may be concluded that drying time could be accurately estimated by the new drying model.

This research was carried out for the effects of large-scale hot spring development on water quality. The Shin-Wul stream, which runs into the Dalchun river, was the object of this study. The water of Shin-wul stream was analyzed seasonally for one year from August, 1987 to August, 1988. The former data were also used. The collected data were input into the QUAL2E-H program, a Model which estimates water Quality. The result was as follows: Even if more than 90% of organics produced by the hot springs were eliminated, the quality of water was still deteriorated. This rendered the water unfit for drinking and agricultral use.
