Quantitative and qualitative characteristics of greenery in suburban residential districts of Metro Manila
This case study was conducted to better understand the present situation of urban greenery in Marikina City, in the suburbs of metropolitan Manila, a typical large Asian city. A vegetation survey was conducted in residential districts of Marikina City, and the quantitative and qualitative characteristics of trees were analyzed. Lot size had some influence on the quantity of greenery in residential lots. In smaller lots, however, quantity did not increase in proportion to lot size. It appears, then, that the land-use controls for individual lots did not function effectively. Quantitative differences of greenery were related to qualitative differences, depending on the year or period of development of the residential area. In the newly developed residential lots, the greenery is comprised mostly of ornamental trees. Under the present circumstances, there is no assurance of sustaining the desired quantity of greenery in smaller residential lots. From these results, we proposed that regulations on lot size/coverage and promotion of tree planting involving local residents are needed to sustain urban greenery in residential districts
Significance of postoperative cross cerebellar hypoperfusion in patients with cerebral hyperperfusion following carotid endarterectomy: SPECT study
Dimensionality dependence of optical nonlinearity and relaxation dynamics in cuprates
Femtosecond pump-probe measurements find pronounced dimensionality dependence
of the optical nonlinearity in cuprates. Although the coherent two-photon
absorption (TPA) and linear absorption bands nearly overlap in both quasi-one
and two-dimensional (1D and 2D) cuprates, the TPA coefficient is one order of
magnitude smaller in 2D than in 1D. Furthermore, picosecond recovery of optical
transparency is observed in 1D cuprates, while the recovery in 2D involves
relaxation channels with a time scales of tens of picoseconds. The experimental
results are interpreted within the two-band extended Hubbard model.Comment: 10 pages, 4 figure

Magneto-optics induced by the spin chirality in itinerant ferromagnet NdMoO
It is demonstrated both theoretically and experimentally that the spin
chirality associated with a noncoplanar spin configuration produces a
magneto-optical effect. Numerical study of the two-band Hubbard model on a
triangle cluster shows that the optical Hall conductivity
is proportional to the spin chirality. The detailed comparative experiments on
pyrochlore-type molybdates MoO with Nd (Ising-like moments)
and Gd (Heisenberg-like ones) clearly distinguishes the two mechanisms,
i.e., spin chirality and spin-orbit interactions. It is concluded that for
=Nd, is dominated by the spin chirality for the dc
() and the incoherent intraband optical transitions between
Mo atoms.Comment: 4 pages, 5 figures. submitted to Phys. Rev.
Assessment of the Impressions of Robot Bodily Expressions Using Electroencephalogram Measurement of Brain Activity
Kummiluokkatoiminnan arviointi
Tämän opinnäytetyön tarkoituksena oli kuvata ja arvioida kummiluokkatoimintaa ja sen vaikutuksia sairaanhoitajaopiskelijan/terveydenhoitajaopiskelijan opintoihin sekä työelämään pääsemiseen ja sopeutumiseen.
Tämä opinnäytetyö toteutettiin empiirisenä tutkimuksena. Kummiluokkatoimintaa arvioitiin kyselyn avulla. Kysely tehtiin sähköisenä Webropol-kyselynä. Kysely lähetettiin sähköpostitse 55 hoitoalan opiskelijalle, jotka olivat olleet mukana kummiluokkatoiminnassa. Kyselyyn vastasi yhdeksän opiskelijaa, vastausprosentti oli 16,36 %. Kysely sisälsi sekä avoimia kysymyksiä että monivalintakysymyksiä. Vastausten analysointiin käytettiin sisällönanalyysiä sekä tilastointia.
Kyselyn tulokseksi saatiin, että opiskelijat eivät pääosin olleet tyytyväisiä kummiluokkatoimintaan sellaisena kuin se oli toteutunut. Kummiluokkatapaamisia oli ollut liian vähän, eikä niillä ollut vaikutusta työn saantiin. Kuitenkin se toiminta, mitä opiskelijoille oli tarjottu, oli mieleistä. Muutaman opiskelijan mielestä toiminta oli lisännyt halua työskennellä Varsinais-Suomen sairaanhoitopiirissä ja yhden mielestä se oli tehnyt työnhausta helpompaa. Myös vierailukäynnit ja esitykset olivat olleet kiinnostavia, niitä olisi vain pitänyt olla enemmän.
Tämän opinnäytetyön tuomaa tietoa voidaan käyttää kummiluokkatoiminnan kehittämiseen, jotta hoitoalan opiskelijat saadaan yhä enemmän sitoutumaan ja kiinnostumaan tulevasta ammatistaan. Saadut tulokset antavat myös lisää syitä kummiluokkatoiminnan jatkamiselle. Jatkotutkimuksina voisi selvittää, miten kummiluokkatoiminta vaikuttaa Turun Yliopistolliseen sairaalaan ja VSSHP:in, eli hyötyykö toiminnasta opiskelijoiden lisäksi myös organisaatio.The purpose of this study was to describe and evaluate the godparent activities and its effects on nursing studies, as well as to work to reach and adjust.
This thesis has been implemented by empirical research. Godparent activity was assessed using an inquiry. The inquiry was conducted by Webropol survey. The inquiry was sent by e-mail of 55 nursing students, who had been involved in godparent activities. Nine students responded to the inquiry, the response rate was 16.36%. The inquiry contained both open questions and multiple choice questions. Content analysis and statistics were used for the analysis of the responses.
The inquiry led to the result that students are not generally been satisfied with the godparent activities as it had been. Godparent meetings were only few, nor did they have the effect of employment. However, it is low, what activities were offered to students was worthwhile. A few view, the activities had added desire to work in Hospital District of Southwest Finland, and one thought it was done work search easier. Also, visits and information lectures were interesting; they would only have been more.
This thesis can be used to develop the godparent activities, to get nursing students to increasingly commit to and interested in their future profession. The information obtained will also provide more reasons to continuation of godparent activities.
Possible further studies could figure out how godparent activities affect the Turku University Hospital and in Hospital District of Southwest Finland, to benefit for the students, but also the organization
Anomalous Hall Effect and Magnetic Monopoles in Momentum-Space
Efforts to find the magnetic monopole in real space have been made in cosmic
rays and in accelerators, but up to now there is no firm evidence for its
existence due to the very heavy mass GeV. However, we show that
the magnetic monopole can appear in the crystal-momentum space of solids in the
accessible low energy region (eV) in the context of the anomalous
Hall effect. We report experimental results together with first-principles
calculations on the ferromagnetic crystal SrRuO that provide evidence for
the magnetic monopole in the crystal-momentum space.Comment: 4 figures, the supporting-online-materails are include
