  • 박새는 도시생태계 내 환경변화를 측정할 수 있는 생물지표종이자 대표적인 식충성 조류로 건전성 유지와 같은 중요한 역할을 맡고 있다. 연구자들은 박새과 조류의 번식생태 파악을 위해 인공새집 조사방법을 활용하고 있으나, 공간적·시간적 한계로 거시적 관점의 연구를 진행하기에는 어려움이 있다. 본 연구는 전문가 중심으로 수행된 기존 인공새집 모니터링이 갖는 한계를 벗어나고자 시민참여 인공새집 모니터링 프로젝트를 설계하였다. '수원시 앞마당 조류 모니터링단'은 시민조사원들의 자발적인 참여를 통해 경기도 수원시 내 녹지공간에 인공새집을 설치하고 박새과 조류의 번식생태를 관찰하는 프로젝트이다. 2021년 2월 9일부터 2월 22일까지 온라인 설문조사를 통해 참가자를 모집하였고, 시민조사원은 2021년 2월 23일부터 8월 31일까지 인공새집 설치부터 관찰까지 직접 수행하였다. 비전문가인 시민조사원들의 진입장벽을 낮추고 일관된 데이터를 수집하기 위해 모니터링 과정 전반에 대한 온라인 교육을 수행하였고 모바일 애플리케이션을 이용하여 인공새집 관찰기록을 수집하였다. 시민참여 인공새집 모니터링 프로젝트에는 98명의 시민조사원이 참여하였고 배포된 206개의 인공새집 중 175(84.95%)개가 수원시 내 녹지공간에 설치되었다. 설치된 인공새집 중 위치 좌표 생성 오류가 발생한 2건을 제외한 173(83.98%)개를 대상으로 시민과학 프로젝트 결과를 확인했다. 시민조사원으로부터 수집한 인공새집 관찰기록은 총 987회이며, 최솟값은 1회, 최댓값은 26회, 평균은 5.71±4.37회로 나타났다. 월별 인공새집 관찰 횟수는 2월 70회(7.09%), 3월 444회(44.98%), 4월 284회(28.77%), 5월 133회(13.48%), 6월 46회(4.66%), 7월 6회(0.61%), 8월 4회(0.41%)로 조사되었다. 설치된 173개의 인공새집 중 57개(32.95%)에서 조류의 이용을 관찰할 수 있었고 박새 12개소(21.05%), 곤줄박이 7개소(12.28%), 미동정 조류 38개소(66.67%)로 확인되었다. 본 연구는 박새과 조류의 번식생태를 조사방법으로 활용되는 인공새집 모니터링에 시민의 참여 가능성을 처음으로 검토한 연구로 향후 시민과학을 접목한 생태모니터링 설계의 기초자료로 활용될 수 있을 것으로 판단된다.

  • Objective: This study aimed to investigate the effects of enrichment resources (a perch, dustbath, and nest) layout in furnished laying-hen cages (FC) on exterior quality of eggs. Methods: One hundred and sixty-eight (168) Hy-Line Brown laying hens at 16 weeks of age were randomly distributed to four treatments: small furnished cages (SFC), medium furnished cages type I (MFC-I), medium furnished cages type II (MFC-II), and medium furnished cages type III (MFC-III). Each treatment had 4 replicates or cages with 6 hens for SFC (24 birds for each SFC) and 12 hen/cage for MFC-I, -II, and -III (48 birds for each MFC-I, -II and -III). Following a 2-week acclimation, data collection started at 18 weeks of age and continued till 52 weeks of age. Dirtiness of egg surface or cracked shell as indicators of the exterior egg quality were recorded each week. Results: The results showed that the proportion of cracked or dirty eggs was significantly affected by the FC type (p<0.01) in that the highest proportion of cracked or dirty eggs was found in MFC-I and the lowest proportion of dirty eggs in SFC. The results of this showed that furnished cage types affected both dirty eggs and cracked eggs (p<0.01). The results also indicated that not nest but dustbath lead to more dirty eggs. Only MFC-I had higher dirty eggs at nest than other FC (p<0.01). The results of dirty eggs in MFC-I and MFC-II compared with SFC and MFC-III seemed suggest that a low position of dustbath led to more dirty eggs. Conclusion: SFC design affected exterior egg quality and the low position of dustbath in FC resulted in higher proportion of dirty eggs.

  • Objectives: The study aims to develop an understanding of the experience of migrant husbands with their South Korean in-laws, specifically from the perspective of migrant husbands from developing countries who reside in South Korea. Method: In total, 13 semi-structured interviews were carried out. Results: The themes drawn from the interview data were "attempting to be accepted as sons-in-law by the in-laws," "interacting closely with in-laws," and "building a nest of their own." When it comes to "struggling to be recognized as sons-in-law" by their Korean families, the migrant husbands in this study met with a high level of opposition from in-laws and sometimes their own family members, made considerable efforts to be accepted as sons-in-law, and then were finally accepted as sons-in-law (although not every migrant husband achieved this). Regarding "interacting closely with in-laws," migrant husbands tried to be recognized as real family members, became hyoja (filial sons) for the sake of their wives and children, and felt a burden about mismatched expectations regarding family roles and obligations. Regarding the final theme, "building a nest of their own," the men tried to be themselves, to attain an equal position to their in-laws, and to maintain a moderate distance between themselves and their in-laws. Conclusions: The study has significant implications for existing government programs designed for multicultural families and how they can be made more inclusive, as well as how new programs can help to improve the relationships between Korean in-laws and migrant husbands.

  • It is known that many insects and animals can return to their nest after exploration, with their own specific homing mechanisms. Their homing navigation methods have been applied to the robotic navigation. In this paper, we test the sector-based image matching method motivated by the honeybee's landmark navigation behaviour. Here, our robotic approach uses the reference compass to identify the current head direction and the relative angular position of landmarks for the navigation. The robot shows desirable homing behaviors if the robot is surrounded by landmarks. The result of robot experiment is in good agreement with that of simulation.

  • 2009년 5~7월까지 전북 진안군 주천면 주양리에 위치한 주자천에서 감돌고기의 일중 산란 타이밍 및 초기 산란위치에 대한 연구를 실시하였다. 감돌고기의 산란은 5월 7일부터 7월 11일까지 이루어졌으며 꺽지 산란장에만 탁란을 했다. 61개 꺽지 산란장 중 56개의 산란장에 탁란했으며, 꺽지 산란 후 1~2일 사이에 시작되었다. 하루 중 감돌고기의 탁란은 꺽지의 공격횟수가 낮게 나타난 6~7시 사이에 가장 높은 빈도로 관찰되었다. 감돌고기가 탁란한 알의 부화율은 지속적인 꺽지의 산란장 방어와 가장 밀접한 상관관계를 나타냈으며, 감돌고기는 자신의 알을 중심으로 난 보호를 하는 꺽지 난괴와 가까운 곳부터 산란을 함으로써 꺽지의 난 보호를 통한 이득을 얻는 것으로 생각된다.

  • Conventional maximum power point tracking (MPPT) methods are ineffective under partially shaded conditions because multiple local maximum can be exhibited on power-voltage characteristic curve. This study proposes an improved cuckoo search (ICS) MPPT method after investigating the cuckoo search (CS) algorithm applied in solving multiple MPPT. The algorithm eliminates the random step in the original CS algorithm, and the conception of low-power, high-power, normal and marked zones are introduced. The adaptive step adjustment is also realized according to the different stages of the nest position. This algorithm adopts the large step in low-power and marked zones to reduce search time, and a small step in high-power zone is used to improve search accuracy. Finally, simulation and experiment results indicate that the promoted ICS algorithm can immediately and accurately track the global maximum under partially shaded conditions, and the array output efficiency can be improved.

  • The Moving-nest Typhoon Model (MTM) was installed on the Korea Meteorological Administration (KMA)'s CRAY X1E in 2006 and started its test operation in August 2006 to provide track and intensity forecasts of tropical cyclones. In this study, feasibility of the MTM forecast is compared with the Global Data Assimilation and Prediction System (GDAPS) of the KMA and the operational typhoon forecast models in the Japan Meteorological Agency (JMA), from the sixth tropical cyclone to the twentieth in 2006. Forecast skills in terms of the storm position error of the two KMA models were comparable, but MTM showed a slightly better ability. While both GDAPS and MTM produced larger errors than JMA models in track forecast, the predicted intensity was much improved by MTM, making it comparable to the JMA's typhoon forecast model. It is believed that the Geophysical Fluid Dynamics Laboratory (GFDL) bogus initialization method in MTM improves the ability to forecast typhoon intensity.

  • We live in two giant pendulum in called 'science' and 'religion'. But science and religion are contained in disparate information with each other, Those two is not easy to achieve convergence. But if you accept the ontological scheme of Great Chain of Being(存在의 大連鎖) in the Perennial philosophy(永遠의 哲學), Debate between religion and science is meaningless 'Great Nest of Being(存在의 대둥지, Great Chain of Being)' is similar to the multiple concentric circles, there are different dimension that the each top level to subsume surrounding the lower level. For example, upper zone 'Mysticism(神秘主義)' includes but transcends(or transcends but includes.) the sub-region theology, psychology, biology and physics. The Perennial philosophy is the great spiritual teachers of the world, philosophers and thinkers have adopted a common worldview, a religious views. Philosophers of the perennial philosophy seem to match the cross-cultural almost unanimous about the general level of the 'Great Nest of Being' for the past 3,000 years. The perennial philosophy made the conclusion that God exists in the world. Several types of view of God existing religions in the world have 'Monotheism(一神論)', 'Pantheism(汎神論)' and 'Panentheism (汎在神論)'. Although traditionally the God of the philosophers is the classical Theism, theological trends of today it is moving in the direction of Panentheism. Panentheism see that god is immanent and transcendent. also Daesoon Thoughts is the position of the Panentheism. so this paper points out the fact that the view of God of the perennial philosophy is precisely consistent with the view of God of Daesoon Thoughts. Wilber says 'envelopment [transcend and include]'. The word translates as 'powol(包越)' in Korean. 'Powol(包越)' means that all the developmental evolution is to surround the sub-region developed into the higher realms. View of the God in the perennial philosophy is 'powol theism(包越的 有神論)'. but 'powol immanent God(包越的 內在神論)' rather than building regulations as 'powol theism(包越的 有神論)'. It would have to be a more accurate representation of it. Because in the existing 'theism(有神論)' the god and humans are thought to exist apart. However, Daesoon Thoughts are deemed to also recognize another universal laws. also Sangje(上帝, the Supreme God) is recognized as a cosmic existence that transcends the laws. This point, as the characteristics of the Daesoon Thoughts, In other religions can not be found. Therefore, More specifically represent(More accurately represent), Sangje of the Daesoon Thoughts can be described as 'powol theism' or 'transcendental and included deism(包越的 理神論)'. Importantly, The idea of God can be captured directly by the discipline. In this sense, In terms of the other religions have no discipline law, the practice [discipline] of the Daesoon Thoughts required in the present age. It has the absoluteness.

  • The Community Health Service considers the family as a service unit and places the emphasis of its service on the health problems and the nursing needs of the family rather than the individual. From the conceptual point of view that tile community health service is both health maintenance and health promotion of the family, the community health nurse should have a knowledge of the growth and development of the family and be responsible for the comprehensive support of normal family development. The community health nurse often is in a position to make a real contribution to normal family development. In order to investigate the relationship between the areas of nursing need and family development, the following objectives were established 1. To discover the general characteristics of the study population by the stage of family development. 2. To discover specific nursing needs in relation to the family developmental stage, and to determine the intensity of the nursing needs and the ability of the family to cope with these needs. 3. To discover overall family health nursing problems in relation to the family developmental stage and determine the intensity of the nursing need and the problem solving ability of family. Definitions : The family developmental stages as classified by Dually were used stage 1. Married couples(without children) stage 2. Childbearing Families (oldest child birth to 30 months of age) stage 3. Families with preschool children (oldest child 2½-to 6 years) stage 4. Families with schoolchildren (oldest child 6 to 13 years). stage 5. Families with teenagers (oldest child 13 to 20 years) stage 6. Families as launching centers (first child gone to last child′s leaving home). stage 7. Middle- aged parents (empty nest to retirement) stage 8. Aging family member (retirement to death of both spouses) The areas of nursing need were defined as those used in the study, "A Comprehensive Study about Health and Nursing Need and a Social Diagram of the Community", by tile Nursing research Institute and Center for population. and Family Planning, July 1974. The study population defiled and selected were 260 nuclear families ill two myron of Kang Hwa Island. Percent, mean value and F- test were utilized in tile statistical analysis of the study result. Findings : 1. General characteristics of the study population by tile family developmental stage ; 1)The study population was distributed by the family developmental stage as follows : stage 1 : 3 families stage 2 : 13 families stage 3 : 24 families stage 4 : 41 families stage 5 : 50 families stage 6 : 106 families stage 7 : 13 families stage 8 : 10 families 2) Most families had 4 or 5 members except for those in stage, 1, 7, and 8. 3) The parents′ present age was older in the higher developmental stage and their age at marriage was also younger in the higher developmental stages. 4) The educational level of parents was primarily less than elementary school irrespective of the developmental stage. 5) More than half of parents′ occupations were listed as laborers irrespective of the developmental stage, 6) More than half of the parents were atheists irrespective of the developmental stage. 7) The higher the developmental stage(from stage 2 to stage 6 ), the wider the distribution of children′s ages. 8) More than half of the families were of middle or lower socio-economic level. 2. Problems in specific areas of nursing need by family developmental stage, the intensity of nursing need and the problem solving ability of the family : 1) As a whole, many problems, irrespective of the developmental stage, occurred in tile areas of Housing and Sanitation, Eating Patterns, Housekeeping, Preventive Measures and Dental care. Problems occurring ill particular stages included the following ; stage 1 : Prevention of Accident stage 2 : Preventive Vaccination, Family Planning. stage 3 : Preventive Vaccination, Maternal Health, Family Planning, Health of Infant and Preschooler. stage 4, 5 : Preventive Vaccination, Family Planning, Health of School Children. stage 6 : Preventive Vaccination, Health of School Children. 2) The intensity of the nursing need in the area of Acute and Chronic Diseases was generally of moderate degree or above irrespective of the developmental stages except for stage 1. Other areas of need listed as moderate or above were found in the following stages: stage 1 : Maternal Health stage 3 . Horsing and Sanitation, Prevention of Accident. stage 4 . Housing and Sanitation. stage 5 : Housing and Sanitation, Diagnostic and Medical Care. stage 6 : Diagnostic and Medical care stage 7 : Diagnostic and Medical Care, Housekeeping. stage 8 : Housing and Sanitation, Prevention of Accident, Diagnostic and Medical Care, Dental Care, Eating Patterns, Housekeeping. 3) Areas of need with moderate problem solving ability or less were as follows : stage 1 : Diagnostic and Medical Care, Maternal Health. stage 2 : Prevention of Accident, Acute and Chronic Disease, Dental Care. stage 3 : Housing and Sanitation, Acute and Chronic Disease, Diagnostic and Medical Care, Preventive Measure, Dental Care, Maternal Health, Health of Infant and preschooler, Eating Patterns. stage 4 : Housing and Sanitation, Prevention of Accident, Diagnostic and Medical Care, Preventive Measure, Dental Care, Maternal Health, Health of New Born, Health of Infant and Preschooler, Health of school Children, Eating Patterns, Housekeeping. stage 5 . Housing and Sanitation, Prevention of Accident, Acute and Chronic Disease, Diagnostic and Medical Care, Preventive Measure, Dental Care, Preventive Vaccination, Maternal Health, Eating Patterns. stage 7, 8 : Housing and Sanitation, Prevention of Accident, Acute and Chronic Disease, Diagnostic and Medical Care, Preventive Measures, Dental Care, Preventive Vaccination, Eating Patterns , Housekeeping. Problem occurrence, the degree of nursing need and the degree of problem solving ability 1 nursing need areas for the family as a whole were as follows : 1) The higher the stages(except stage 1 ), the lower the rate of problem occurrence. 2) The higher the stage becomes, the lower the intensity of the nursing need becomes. 3) The higher the stages (except stages 7 and 8), the higher. the problem solving ability. Conclusions ; 1) When the nursing care plan for the family is drawn up, depending upon the stage of family development, higher priority should be give to nursing need areas ① at which problems were shown to occur ② where the nursing need is shown to be above moderate degree and ③ where the problem solving ability was shown to be of moderate degree. 2) The priority of the nursing service should be Placed ① not on those families in the high developmental stage but on those families in the low developmental stage ② and on those areas of need shown in stages 7 and 8 where the degree nursing need was high and the ability to cope low.
