All the available information, including distributional ranges and biology of each taxon, is provided. The keys to the genera and species of Oidaematophotini is given. Illustrations of the images and male and female genitalia are provided.

In the equilibrium theory of tides by Newton, tide on the Earth is a phenomenon driven by differential gravity contributed both by the Sun and the Moon. Due to the direct link of the generic tidal effect to the oceanic tides, college students in the earth science education department are exposed to this theory through oceanography lectures as well as astronomy lectures. Common oceanography textbooks adopt a non-inertial reference frame fixed to the Earth in which the fictitious, centrifugal force appears. This has a potential risk to provide misconceptions among students in various aspects including the followings: 1) this is how Newton originally derived the equilibrium theory of tides, and 2) the tide is a phenomenon appearing only in rotating systems. We show that in astronomy, a much simpler description, which employs the inertial frame, is generally used to explain tides and thus causes less confusion. We argue that the description used in astronomy is preferable both in the viewpoints of simplicity and ease of interpretation. Moreover, on a historical basis, an inertial frame was adopted by Newton in Principia to explain tides. Thus, the description used in astronomy is consistent with Newton's original approach. We also present various astrophysical tides which do not comply with the concept of centrifugal force in general. We therefore argue that the description used in oceanography should be compensated by that in astronomy, due to its complexity, historical inconsistency and limited applicability.

이 연구는 7차 고등학교 지구과학 II 교과서의 내용 중 화성암의 조직 개념에 대한 본문 진술을 분석하고 문제점을 지적하고 그 개선 방안을 모색하였다. 과학 교과서의 개념 진술이 정확하지 않아 학습자들에게 오개념을 유발하거나 재강화할 가능성이 있는 여러 진술문이 발견되었다. 화산암에 대하여 세립질, 유리질 또는 반상 조직을 기술하고 있으며, 심성암에 대하여 완정질, 입상, 조립질 및 등립질 조직 등 다양한 조직을 제시하고 있다. 이들은 화성암 조직 분류체계 기준의 혼란에 관련된 것들이었다. 화성암의 조직에 대한 정확한 개념을 전달하기 위한 화성암 분류 기준의 개선방안들을 제시하였다. 화성암을 구성광물의 입도, 상대적인 크기와 결정도에 따라 화산암에는 비현정질 또는 반상 조직을, 심성암에는 현정질 또는 완정질, 등립상 조직을 사용하여야 한다.

(Aulaeodes), Eoophyla flavifaseialis (Hampson, 1917) comb. n. (Aulaeodes), Eoophyla longiplagialis (Hampson, 1917) comb. n. (Aulaeodes), the last three species are from Irian Jaya; and Eoophyla stresemanni (Rothschild, 1915) (Aulaeodes) comb. n. from Ceram. The male and female genitalia are illustrated together with pictures of the adults. The diagnostic features of the species are given and the nearest relatives are indicated. All new species are Philippine endemics. The rate of endemism in the Acentropinae of the Philippines is about 85%. This remarkable high percentage, corroborating the notion that the Philippines are a hot spot of biodiversity in South East Asia, points to the particular geographic situation and geological history of the Philippine Islands.

Purpose ‒ The study is primarily aimed at framing "Position Descriptions" for some key positions in the executive cadre of the testing department of CESC Limited. Research design, data, and methodology ‒ The questionnaire, interview, and observation methods have been used for the purpose of data collection. The position descriptions are validated by superiors belonging to the respective departments. Results ‒ It has been found that there is overlapping of job duties and job responsibilities in the department. This overlapping is quite alarming for the organization and may even become a hurdle in the path of its progress. It can be seen as a classic case of de-layering. Conclusions ‒ The study concludes that good communication along with interpersonal and negotiation skills are absolutely essential to facilitate the performance of the day-to-day duties of a job, including handling the union, solving IR related issues, development of the subordinates, job setting, distribution and allocation, etc. Position descriptions will help in the alignment of the employee direction, and can be a useful tool to aid the communication between management and employees.

A purpose of this study was to provide the helpful information about operation of revised science curriculum by analyzing many contents about acid rain with various aspects, which was written in science textbook of 10 year according to the 7th national curriculum. The results show that there was the lack of educational systemicity among elementary school, middle school, and high school science curriculum and the lack of explanation for occurrence and standard level of acid rain, pH 5.6. And It could be categorized the effect of acid rain into four groups and experiment or experiment activities into three groups.
