  • Radiographs were made of the feet of one hundred and twenty four normal children who were ranged in age from 1 to 13 years. On lateral radiographs that were made with the feet in standing, the talo-first metatarsal, calcaneal pitch and calcaneo-fifth metatarsal angles and arch ratio were measured. Most of the children in this study revealed flattened feet in earlier ages and the mean values were changed with age up to normal range later in the early school ages. These data might provide one of the standard for assessment of the flatfoot in children. However, the diagnosis and treatment of the flatfoot should be based on clinical assessment and radiographic values should not determine clinical management even if the values are beyond the normal range.

  • Since the first description by Cotton, there have been sporadic reports about the inferior subluxation of the shoulder. Nevertheless there is still a lack of consensus regarding the mechanism of occurrence, evolution and treatment. We have experienced six cases of inferior sublusation(five cases after trauma and one case after surgery) which resolved over time. Analysis of the clinical informations including serial radiographs, data from clinical examination and electromyography(EMG) revealed the following results. All the five post-traumatic inferior subluxations were noted in women with an average age of 59 years after direct trauma resulting in fracture of the proxiaml hrnerus(4) or clavicle(1), of which nerve injury was proven by EMG in three. One case occurred after Bankart repair by stretch injury to the axillary nerve. The presenting symptom was unusually severe pain on passive motion. Absence of anterior or posterior displacement wasl confirmed by radiographs. All the cases seemed to have delayed onset of subluxation except one. The subluxed hu.meral head was concentrically reduced at an average 11 weeks(range 3-23 weeks) from the supposed time of occurrence and the acromiohumeral interval measUred on the standing anteroposterior radiographs decreased to 9.4 mm ftom 23 mm. Improvement of pain paralled the reduction. In conclusion, the most common cause of transient inferior subluxation was nerve injury in ou~ series and the prognosis was excellent, however protraction of recovery or leaving permanent subluxation would be possible if .the injured nerve is unrecoverable.

  • Mobile computing environment makes it possible for computing activities to be maintained during movement even if a user changes its network point of attachment. Mobile IP is a standard protocol designed to be used in such mobile computing environment. However, Mobile IP has a drawback to incur a lot of handoff delays and waste network resources, since CoA(Care of Address) registration packets need to go through a HA(Home Agent) first whenever a mobile node moves. To solve this long-standing problem, this paper proposes a new scheme that, for infra-domain movement, efficiently performs local handoff without notifying the HA Specifically, based on the notion of load balance, the proposed scheme allows every FA(Foreign Agent) in a domain to become the root FA(also known as domain FA) dynamically, thus distributing the registration task into many other foreign agents. The dynamic root assignment through load balancing ultimately leads to fast network response due to less frequent transmission of registration packets.

  • In the second half of the twentieth century, fashion shows were a long-standing promotional medium and changed form and styles as times changed. In the past, if a model were on the stage simply to showcase a brand's work, the stage would have been transformed into a more active space, displaying various performances or seasonal themes combined with art. Then in the 2000s, there was an increasing number of instances when the global fashion industry of used figurative objet in organizing a fashion show's stage. In particular, because fashion shows require audience response and satisfaction, producing displays using objet is an effective marketing method. In the early 2000s, many brands were already introducing runway displays using objet, and these cases are expected to increase further in the future. This collection of 23 ready-to-wear models, which constituted the runway display, was by utilizing the objet more than five times from the 485 brands listed in Vogue's runway category. Based on our previous research, we classified the objet expressive characteristics as reproducibility, simplicity, non-artificiality, and fantasy. Among the 207 collections that we analyzed, the collection that utilized objet in its runway display had 170 circuits. Using objet in the runway display leverages visual language which allows one to communicate the season's concept, brand identity, and desired message more easily. Futhermore, it was spatially expressed to create feeling of satisfaction.

  • Objective: This study aimed to compare muscle structure, balance, and gait parameters between healthy adults and persons with stroke and to analyze the correlation among these variables. Design: Cross-sectional study. Methods: Twenty persons with stroke (11 male, 9 female) and twenty healthy participants (9 male, 11 female) were included. Ultrasound images of the triceps surae and the tibialis anterior were acquired in sitting resting, sitting co-contraction, and standing resting positions and also during the functional reach test (FRT) and single leg anterior reaching test (SLART). Muscle thickness and fascicle length were measured. Spatiotemporal parameters of gait were measured using a pressure walkway. Gait speed, cadence, step length, stride length, stance time, and swing time were measured. Results: Changes in percent fascicle length were significantly greater in the gastrocnemius and soleus (SOL) muscles of healthy adults in the sitting co-contraction position (p<0.05). The percent fascicle length of the SOL in FRT and SLART were significantly greater in healthy adults (p<0.05). The mid-stance phase of stroke patients was shorter than healthy adults (p<0.05). A negative correlation was observed between percent fascicle length of the SOL in the sitting co-contraction position and the proportion of the mid-stance phase (p<0.05). Conclusions: The function of the triceps surae is affected in persons with stroke when compared with healthy adults. This can lead to difficulty in performing tasks that involve forward transfer of weight. If the triceps surae is not sufficiently secured, the possibility of compensation in the stance phase increases during gait.

  • In this note we examined some terms, parallel lines and angles in elementary school mathematics and middle school mathematics respectively. Since some terms are represented early in elementary school mathematics and not repeated after, some students are not easy to apply the terms to their lesson. Also, since the relation between parallel lines and angles are treated intuitively in 7-th grade, applying the relation for a proof in 8-th grade would be meaningless. For the variety of mathematics education, it is desirable that the relation between parallel lines and angles are treated as postulate. Also, for out standing students, it is desirable that we use deductive reasoning to prove the relation between parallel lines and angles as a theorem. In particular, the treatments of vertical angles and the relation between parallel lines and angles in 7-th grade text books must be reconsidered. Proof is very important in mathematics, and the deductive reasoning is necessary for proof. It would be efficient if some properties such as congruence of vertical angles and the relation between parallel lines and angles are dealt in 8-th grade for proof.

  • To build a suitable National Health Care System for the coming 21s1 century, Nursing must also be renewed. The future Korea will be united and the majority of its population will raidly consist of the aged. Economically standing on the same level with developed countries the growth of scientific technologies will foster communications, firing astounding changes in the medical field. While the overall life style pattern of Koereans not to mention the structure of diseases undergo change, the possibility that the reckless induction of high-tech health care may only cause medical fees to eascafate. It can전so be expected that the health care system will evolve towards the consumers. Nursing in the 21s1 century will be of two scenarios according to WHO, which presents the role of the nurse. The first scenario is that "a gen-eric health care work force" namely a "care giver" will replace all other health professions. If Nursing does not become the compatent profession fitting to this purpose it will eventually dei out. The second scenario is that nurses who are educated in a well grounded and extensive general background and have command of a specialized area will undertake services varying from health pro-motion to treatment and rehabilitation both direct and indirectly, while supervising other personnel. The nurse here would become the "care giver". To become the necessary health care profession in the 21s1 century, nurses should be provided with more educational opportunities, variating in its con-tents, course, and system, enabling them to grow. Clair Faign points out that the minimal educational entry for the nursing profession is a 4 year undergraduate education in this aspect, now in the time to set the future of Nursing into the course of the first scenario. A new educational system stipulating a baccalaureate nursing degree is in urgent need, and aside from govermental actions nurse themseives should formaily officiallze this process, striving for quality assurance. While considering 6 years nursing education programs, multifarious degree courses for existing 3 years educated nurse should be provided Junior nursing schools must devise measures to grow into baccalaucate institutions, also. Among the existing courses, the Self Study Degree Program should be converted into RN, BSN courese provided by universities, and clinical training for the University on the Air must be supplimented, The possibility of establishing nursing courses into commercial high school programs only jeopardizes the development of the nursing profession.

  • During the last two and a half decades, philosophical interest in the aesthetics of nature and environment has been gained momentum. One of the most coherent theories in this arena of debate has been developed over a series of articles by Allen Carlson. The purpose of this paper is to examine Carlson's theory critically and suggest an alternative aspect that remains untouched by his model. Briefly stated, Carlson's view of the appreciation of nature is that it is a matter of under standing nature under suitable scientific categories. His argument, based on the objectivist epistemology, is basically a disjunctive syllogism : a) The concept of appreciation, derived from traditional disinterestedness and Stolnitz's aesthetic attitude, provides an insight into the explanation of aesthetic appreciation of nature, and is objectivistic in the light of its object-oriented character. b) Nature must be appreciated as nature itself, and the natural environmental model is the appropriate loci of our nature appreciation. c) The paradigmatic form of our nature appreciation is order appreciation. d) There can be a correct and objective aesthetic judgment of nature, and the sources of guiding categories pertinent to it is natural science and natural history. In regarding nature as an environment and as natural, his natural environmental model is meaningful. Nevertheless, his stance results in some serious problems : a) The natural environmental model excludes certain very common appreciative responses to nature-responses of a less intellective, more visceral sort. Therefore, the arousal model with appropriate emotions might be one of our characteristic forms of nature appreciation. b) Even if we consider the scientific knowledge as an objective source of our nature appreciation, this gives rise to the question of whether the natural science can be objective or not. Is there an objectivist aesthetic appreciation of nature\ Does aesthetic appreciation of nature need to be science-based\

  • In computer-mediated idea generation where contributions can be anonymous, the ability to accurately monitor performances is limited, inducing social loafing. Prior research has suggested that social loafing is likely an important factor in reducing task performance. Researchers have theorized that loafing could be minimized if clear performance feedback is provided. Our prior study evidences a substantial performance gain by the provision of real time performance information about who is contributing and who is not. However, our prior study incorporated the quantity feedback only to create a larger pool of ideas based on the long-standing assumption (i.e., quantity breeds quality), not considering the quality feedback. As a result, taking advantage of anonymity in the form of pseudonymity, individuals in almost all groups exhibited a tendency of self-presentation by capitalizing on ideas of which quality was low and even frivolous (i.e., junk comments) toward the later stages of the session. Thus, we have learned that the quantity performance feedback alone does not have enough restrictiveness to consistently control the performance behavior throughout the session. Since a process chart allows participants to monitor process variation by comparing new performance data to past performance data, we incorporated real-time visual process performance feedback to reveal performance histories by connecting the sequence of idea quality scores in a time-series format. Using this environment, a laboratory experiment was conducted with five-member groups that examined the influence of both identifiability (i.e., anonymity versus pseudonymity) and process performance feedback (i.e., yes or no) in a $2{\times}2$ factorial design. The result showed that groups in the process performance feedback treatment outperformed groups in the no feedback treatment. Additionally, process performance feedback and identifiability interacted such that groups in the process performance feedback/pseudonymity treatment had the highest performance. The implications of these findings for future research, as well as the implications for the design of group idea generation procedures are discussed.
